• I cut-to-move DCIM folder to ext SD when an auto android OS update popped up b4 I could choose target - Cannot recover 200+ photos

  - by ZeroG

  I was downloading my Exhibit II's DCIM camera folder (with month's of photos inside) to its external SD card, in order to transfer them into my laptop. In my overconfidence, I hurriedly chose cut-to-move (rather than copy-to-move) when KABOOM! —an automatic Android OS update popped up before I could choose the target!!! I figured everything was in cache & calmly tried to go through with the update. But that was not a typically seamless event. It showed downloading icon but hmm… since I rooted the phone it brought the command line up & recovery sequence. But neither Android nor I had yet downloaded any alternate custom ROM Files to internal SD to update from! So were they trying to make me unroot my phone by giving me some bogus update on the fly or just give me a hard time in trying to hand me down an unrooted ROM that I'd have to figure out how to root again? Yes, I know there was that blurb about overwriting a file of the same name but I was trying to shake the darn stubborn update being forced on my phone during this precarious moment. I thought I had frozen or turned off all those auto-updates previously. Anyway, phones are small & fingers are big (sigh)... I tried to reboot into safe mode but the resultant photo file was partially overwritten (200 files had names but Zero bytes in them). I thought maybe it was still hung in cache or deposited somewhere else but I have searched everywhere with file managers. Since I did not have Titanium backing up camera, photo folder or gallery, I cannot recover 200+ photos. Dumb. You can understand my dilemma as I am involved in the arts & although just a camera phone, most of these photos were historic & aesthetic or at least as to subject matter. Photo-ops don't reoccur. I have tried a couple of recovery apps from the market like Search Duplicates & Recover to no avail. I was only able to salvage stuff I'd sent out in messages. I've got several decades in computers & this is such a miserable beginner's piece of bad luck I can't believe it happened to me. They were precious photos! Yes, I turned on Titanium since & yes I even tried USB to laptop recoveries. Being on a MacBookPro I'm trying androidfiletransfer.dmg, but I'd have to upgrade to Peach Sunrise to get above Android 3.0 for that App to recognize the phone via USB & the programmer says installation zeros your data, so that pretty much toasts any secret hidden places where these photos may have been deposited. Don't want to do that & am still trying to find them. They certainly didn't make it to my external SD Card. If any of you techies out there know anything, please help & thanks. Despite decades of being in computing, unfamiliar & ever-changing hard or software can humble even the most seasoned veterans.

• reiserfsck on lvm

  It seems like my filesystem got corrupted somehow during the last reboot of my server. I can't fsck some logical volumes anymore. The setup: root@rescue ~ # cat /mnt/rescue/etc/fstab proc /proc proc defaults 0 0 /dev/md0 /boot ext3 defaults 0 2 /dev/md1 / ext3 defaults,errors=remount-ro 0 1 /dev/systemlvm/home /home reiserfs defaults 0 0 /dev/systemlvm/usr /usr reiserfs defaults 0 0 /dev/systemlvm/var /var reiserfs defaults 0 0 /dev/systemlvm/tmp /tmp reiserfs noexec,nosuid 0 2 /dev/sda5 none swap defaults,pri=1 0 0 /dev/sdb5 none swap defaults,pri=1 0 0 [UPDATE] First question: what "part" should I check for bad blocks?

• Linux bcm43224 wifi adapter slows down a couple minutes after boot

  - by Blubber

  I just installed Ubuntu on my mid 2012 MacBook Air. Everything worked out of the box, but the wifi is showing some weird behavior. When I first login it's really fast, loading google.com is near instant, and browsing in general feels at least as smooth as it did on Mac OS. However, after a couple minutes the connection slows down dramatically, sometimes it takes over 5s to load google.com, a simple reboot fixes the problem for another couple minutes. Specs: Wifi: 02:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01) Driver: open-source brcmsmac driver Kernel: Linux wega 3.8.0-21-generic #32-Ubuntu SMP Tue May 14 22:16:46 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Distro: Ubuntu 13.04 (uptodate) I tried a number of things, none of which actually helped Use proprietary sta driver from broadcom Installed firmware into /lib/firmware/brcms (which, as far as I can tell from logs, does not get loaded at all) Switch router to only use 2.4 OR 5 GHz Set router to only use a OR g OR n Set router to use AES encryption only Turned off power management on the adapter Set regulatory region to the correct value (NL) on both router and laptop Disable ipv6 Nothing seems to help, the slowdown always occurs. I did notice that the latency (ping google.com) stays roughly the same (around 9ms).

• Upgraded Ubuntu, all drives in one zpool marked unavailable

  - by Matt Sieker

  I just upgraded Ubuntu 14.04, and I had two ZFS pools on the server. There was some minor issue with me fighting with the ZFS driver and the kernel version, but that's worked out now. One pool came online, and mounted fine. The other didn't. The main difference between the tool is one was just a pool of disks (video/music storage), and the other was a raidz set (documents, etc) I've already attempted exporting and re-importing the pool, to no avail, attempting to import gets me this: root@kyou:/home/matt# zpool import -fFX -d /dev/disk/by-id/ pool: storage id: 15855792916570596778 state: UNAVAIL status: One or more devices contains corrupted data. action: The pool cannot be imported due to damaged devices or data. see: http://zfsonlinux.org/msg/ZFS-8000-5E config: storage UNAVAIL insufficient replicas raidz1-0 UNAVAIL insufficient replicas ata-SAMSUNG_HD103SJ_S246J90B134910 UNAVAIL ata-WDC_WD10EARS-00Y5B1_WD-WMAV51422523 UNAVAIL ata-WDC_WD10EARS-00Y5B1_WD-WMAV51535969 UNAVAIL The symlinks for those in /dev/disk/by-id also exist: root@kyou:/home/matt# ls -l /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J90B134910* /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51* lrwxrwxrwx 1 root root 9 May 27 19:31 /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J90B134910 -> ../../sdb lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J90B134910-part1 -> ../../sdb1 lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J90B134910-part9 -> ../../sdb9 lrwxrwxrwx 1 root root 9 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51422523 -> ../../sdd lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51422523-part1 -> ../../sdd1 lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51422523-part9 -> ../../sdd9 lrwxrwxrwx 1 root root 9 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51535969 -> ../../sde lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51535969-part1 -> ../../sde1 lrwxrwxrwx 1 root root 10 May 27 19:15 /dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51535969-part9 -> ../../sde9 Inspecting the various /dev/sd* devices listed, they appear to be the correct ones (The 3 1TB drives that were in a raidz array). I've run zdb -l on each drive, dumping it to a file, and running a diff. The only difference on the 3 are the guid fields (Which I assume is expected). All 3 labels on each one are basically identical, and are as follows: version: 5000 name: 'storage' state: 0 txg: 4 pool_guid: 15855792916570596778 hostname: 'kyou' top_guid: 1683909657511667860 guid: 8815283814047599968 vdev_children: 1 vdev_tree: type: 'raidz' id: 0 guid: 1683909657511667860 nparity: 1 metaslab_array: 33 metaslab_shift: 34 ashift: 9 asize: 3000569954304 is_log: 0 create_txg: 4 children[0]: type: 'disk' id: 0 guid: 8815283814047599968 path: '/dev/disk/by-id/ata-SAMSUNG_HD103SJ_S246J90B134910-part1' whole_disk: 1 create_txg: 4 children[1]: type: 'disk' id: 1 guid: 18036424618735999728 path: '/dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51422523-part1' whole_disk: 1 create_txg: 4 children[2]: type: 'disk' id: 2 guid: 10307555127976192266 path: '/dev/disk/by-id/ata-WDC_WD10EARS-00Y5B1_WD-WMAV51535969-part1' whole_disk: 1 create_txg: 4 features_for_read: Stupidly, I do not have a recent backup of this pool. However, the pool was fine before reboot, and Linux sees the disks fine (I have smartctl running now to double check) So, in summary: I upgraded Ubuntu, and lost access to one of my two zpools. The difference between the pools is the one that came up was JBOD, the other was zraid. All drives in the unmountable zpool are marked UNAVAIL, with no notes for corrupted data The pools were both created with disks referenced from /dev/disk/by-id/. Symlinks from /dev/disk/by-id to the various /dev/sd devices seems to be correct zdb can read the labels from the drives. Pool has already been attempted to be exported/imported, and isn't able to import again. Is there some sort of black magic I can invoke via zpool/zfs to bring these disks back into a reasonable array? Can I run zpool create zraid ... without losing my data? Is my data gone anyhow?

• How to restore Linode to Vagrant VM?

  - by Iain Elder

  I'm trying to set up a Linux development environment so I can safely make changes to my website without breaking the live site. Linode hosts my live site. A simple solution would be to host my development server on Linode as well, but I want to avoid doubling my hosting costs. The cheapest way I see is to use Vagrant on my Windows workstation to host my development environment. After I attempt to restore the backup to Vagrant and reboot the VM, I can no longer ssh into the Vagrant host. It's probably because by restoring the backup I overwrite some special Vagrant configuration, but I'm not sure how to avoid that. How do I make this approach work? If my approach is fundamentally wrong, can you suggest an alternative? Creating the backup On the Linode I used these commands to create a compressed copy of the entire filesystem, while ignoring things that shouldn't be included in the backup: $ sudo rsync -ahvz --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/backup/*} /* /backup/2 $ sudo tar -czf /backup/2.gz /backup/2 The backup file is called 2.gz because this is thesecond backup. The first backup is called 1.gz. I use WinSCP to copy the backup file to my Windows workstation. Setting up the Vagrant host I need a Vagrant box that matches my Linode operating system (Ubuntu 12.04.3 LTS, kernel 3.9.3). I selected the closet match from vagrantbox.es: Ubuntu Server Precise 12.04.3 amd64 Kernel is ready for Docker (Docker not included) On my workstation I ran these commands to add the box and initialize and boot an instance: $ vagrant box add ubuntu-precise http://nitron-vagrant.s3-website-us-east-1.amazonaws.com/vagrant_ubuntu_12.04.3_amd64_virtualbox.box $ mkdir linode-test $ cd linode-test $ vagrant init ubuntu-precise $ vagrant up Now Vagrant is running a machine with SSH on port 2222. The operating system version is the same. The kernel version is 3.8.0. Sounds close enough. Restoring the backup With WinSCP I copied the backup file 2.gz to /home/vagrant/2.gz on the Vagrant box. With PuTTY I connected via ssh to my new Vagrant box: On the box move the backup to the filesystem root. $ sudo mv 2.gz / Extract the archive to the filesystem root: $ sudo tar -xvpz -f 2.gz -C / --strip-components=2 (I discovered I need to use strip components because all files in the archive have the prefix backup/2/. I'll fix this for the next backup.) After the tar command completes, I log out of the box. Testing the backup When I try to log in again, it doesn't let me log in as vagrant with a password any more. It does let me log in as iain, my user on the live Linode, with a password. That surprised me because I disabled password authentication on my live Linode. I figured that I have to restart the ssh service for the change to take effect. Instead of restarting just ssh, I chose to restart the whole system. Now I can't even get to the login screen. PuTTY says "connection refused" when I try to connect. What went wrong?

• Install Intel USB 3.0 eXtensible Host Controller Driver for Windows Server 2008 R2 x64

  - by ffrugone

  According to Intel and Dell, by board is technically a 'desktop' board and they therefore do not support Intel USB 3.0 eXtensible Host Controller drivers for Windows Server 2008 (R2 x64). I'm trying to find a workaround. I found an entry on someone who tried to tackle this, but I can't make his fix work for me. Below, I have copied both his entry, and my reply. I'm a loyal stackoverflow user, and hopefully the people here at serverfault can help me: anyforumuser Re: GA-Z77X-UD5H USB3 Drivers not installing? « Reply #6 on: July 05, 2012, 04:12:59 am » Thanks to JoeMiner , his process for the network drivers gave me the clues to figure out to get the USB3 drivers working. I have got the intel USB3 drivers working at full speed in win server 2008r2 you have to edit the following file : 1. mup.xml in change the "Windows7" to "W2K8" 2. in setup.if2 under [groups] line starting with "HSCSDRIVER " change the "IsOS( ... )" entry to "IsOS(WIN2008_R2,WIN2008_R2_MAXSP)" inf files for all copy the content of the [Intel.NTAMD64.6.1] group to the [Intel.NTAMD64.6.2] group driver folders. here i am not entirely sure which is correct so there are some double up's. in the drivers folder copy the "Win7" folder to "win2008" , "win2008_r2" and "x64" ie your drivers folder should now contain the "win2008" , "win2008_r2" and "x64" folders and they contain contents of the win7 folder (the inf files should of already been fixed) Run install , It should install properly and work now. You will have to reboot If it doesn't work remove the intel usb3 controllers from device manager and get it to "scan for hardware changes" Good luck !!! benevida Re: GA-Z77X-UD5H Intel Network Drivers not installing? « Reply #7 on: August 13, 2012, 02:21:14 pm » Thank you anyforumuser! A process for getting this driver installed was exactly what I needed. However, I've hit a snag. I believe I've followed every step exactly as written, but I'm getting an error during installation. I get the message "One or more files that are required for installation are either missing or corrupted. Setup will exit." Behind the error, the 'Setup Progress' shows the current step as "Copying File: C:\Program Files (x86)\Intel\Intel(R) USB 3.0 eXtensible Host Controller Driver\Drivers\iusb3xhc.man". I've checked the installation files, and iusb3xhc.man seems to be a viable file in all of the Windows 2008 sub-directories of the Drivers folder. Therefore I don't see how the file could be missing and I doubt that it is corrupted, (although it does NOT exist in the \Drivers\HCSwitch folder). I opened 'Setup.if2', and there are two aspects to the step of copying iusb3xhc.man that caught my eye. First, the steps immediately preceding are set to 'error=ignore'. If they hadn't completed successfully, this is the first step where we'd hear about it. Second, this is the first step where the relative path '%source%\drivers\%_os%\%_ia%\' is used. If I haven't named the Windows 2008 sub-directories correctly, I could see where things are fouling up. In any event, if someone could take a look and make suggestions I'd appreciate it. Thank you.

  My apache installation is running php as fastcgi, and the virtual hosts are pointing to /home/*/public_html. and the fastcgi are home/*/cgi-bin/php.fcgi the public_html setup with selinux was: /usr/sbin/setsebool -P httpd_enable_homedirs 1 chcon -R -t httpd_sys_content_t /home/someuser/public_html The owner and group are the user, for example the user "someuser": ls -all /home/someuser/cgi-bin/ drwxr-xr-x 2 someuser someuser 4096 Sep 7 13:14 . drwx--x--x 6 someuser someuser 4096 Sep 6 18:17 .. -rwxr-xr-x 1 someuser someuser 308 Sep 7 13:14 php.fcgi ls -all /home/someuser/public_html/ | greep info.php -rw-r--r-- 1 someuser someuser 24 Sep 3 16:24 info.php When is visits the site I get "Forbidden ..." and the log said: [Fri Sep 07 12:02:51 2012] [error] [client x.x.x.x] (13)Permission denied: access to /cgi-bin/php.fcgi/info.php denied My selinux conf is: SELINUX=enforcing SELINUXTYPE=targeted SETLOCALDEFS=0 So I kill Selinux (SELINUX=disabled), reboot the system and everything works !!!!! The problem is Selinux, I don't want disable Selinux. I trying this with no success: setsebool -P httpd_enable_cgi 1 chcon -t httpd_sys_script_exec_t /home/someuser/cgi-bin/php.fcgi chcon -R -t httpd_sys_content_t /home/someuser/cgi-bin Or maybe is better change Selinux SELINUX=enforcing to SELINUX=permissive And disable selinux for httpd ?

• can't login to new install of SQL 2008 x64 via SSMS

  - by tpcolson

  I have performed a fresh install of SQL 2008 x64 on a fresh install of Server 2008 R2 x64 in an AD environment. Upon install completion, I cannot login to the SQL Instance via SSMS, with the following error: Login failed for user domain\user. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: ]. Background: the server is correctly joined to the AD Domain, the install was performed with defaults, windows authentication only (per organizational rules), the SQL install completes with no errors, domain\user was added as SQL Amin during setup account provisioning, I am logged into to console as domain\user when this error occurs, windows firewall is OFF, UAC is ON (an will never be turned off in accordance with organizational policy). To troubleshoot this error I have tried: Run SSMS as administrator: fail; Start SQL in single user mode, run SSMS: fail Start SQL in single user mode, run SSMS as administrator: Success Start SQL in single user mode, run SSMS as administrator, remove domain\user from sysadmin group, re-add, run SSMS: fail; Any combination and permutation of log off and log on, reboot, and chant gregorian prayers: fail; Reimage server with 2008 x64, slipstream SP2 into SQL 2008 install, all above troubleshooting steps are repeatable exactly, so I've narrowed this down to not being a SP issue; (this is NOT 2008 SQL R2) Any suggestion on how to grant management access to this fresh install of SQL 2008 via SSMS? Our organizational policy is no console access to servers, management will be done via management tools intalled on client workstations. domain\user is a group of 8 users whom will have SSMS installed on workstations. However, we can't even access SQL via SSMS from the console! We cannot deploy this in an environment where these 8 users will have to sneak into the server closet on the weekends and have console access to SQL and run SSMS as administrator. EDIT: domain\group is a replacement for the actual object; the queries indicate that domain\group does indeed have the right privelges....!?! 1> EXEC xp_logininfo 'domain\group' go account name type privilege mapped login name permission path 'domain\group' group admin 'domain\group' NULL xp_logininfo seems to show 'domain\group' in the sql admin group; 1> SELECT A.name AS 'Role', B.name AS 'Login' 3> FROM sys.server_role_members C 5> INNER JOIN sys.server_principals A ON A.principal_id = C.role_principal_id 7> INNER JOIN sys.server_principals B ON B.principal_id = C.member_principal _id 9> go Role Login sysadmin sa sysadmin NT AUTHORITY\SYSTEM sysadmin NT SERVICE\MSSQLSERVER sysadmin NT SERVICE\SQLSERVERAGENT sysadmin domain\group 1> SELECT PRINCIPAL_ID AS [Principal ID], 2> NAME AS [User], 3> TYPE_DESC AS [Type Description], 4> IS_DISABLED AS [Status] 5> FROM sys.server_principals 6> GO Principal ID User Type Description Status ------------ ------------------------------------------------------------------- ------------------------------------------------------------- ------------------ ------------------------------------------ ------ 1 sa SQL_LOGIN 1 2 public SERVER_ROLE 0 3 sysadmin SERVER_ROLE 0 4 securityadmin SERVER_ROLE 0 5 serveradmin SERVER_ROLE 0 6 setupadmin SERVER_ROLE 0 7 processadmin SERVER_ROLE 0 8 diskadmin SERVER_ROLE 0 9 dbcreator SERVER_ROLE 0 10 bulkadmin SERVER_ROLE 0 101 ##MS_SQLResourceSigningCertificate## CERTIFICATE_MAPPED _LOGIN 0 102 ##MS_SQLReplicationSigningCertificate## CERTIFICATE_MAPPED _LOGIN 0 103 ##MS_SQLAuthenticatorCertificate## CERTIFICATE_MAPPED _LOGIN 0 105 ##MS_PolicySigningCertificate## CERTIFICATE_MAPPED _LOGIN 0 257 ##MS_PolicyTsqlExecutionLogin## SQL_LOGIN 1 259 NT AUTHORITY\SYSTEM WINDOWS_LOGIN 0 260 NT SERVICE\MSSQLSERVER WINDOWS_GROUP 0 262 NT SERVICE\SQLSERVERAGENT WINDOWS_GROUP 0 263 ##MS_PolicyEventProcessingLogin## SQL_LOGIN 1 264 ##MS_AgentSigningCertificate## CERTIFICATE_MAPPED _LOGIN 0 265 domain\group WINDOWS_GROUP 0 (21 rows affected)

• Windows 7 sometimes boots in VGA mode

  - by TuxRug

  I have an Asus G50VT-x5 laptop with nVidia GeForce9800M-GS graphics. Normally, Windows boots normally, but about 20% of the time (rough estimate), it will boot with the fallback VGA driver, maxing out at 800x600 with no Aero. I've checked the system logs and there is nothing indicating an error loading the nVidia driver. It even specifies in the logs that the Nvidia Display Driver service started successfully, even though it has booted in safe graphics mode. This has been happening for a while, but it's happening a little more often now than it was before. Since the first time my system exhibited this behavior, I have updated my graphics driver a handful of times. I used System Information for Windows to check for problems there, but the only thing that stood out was the following: Core Temperature 4486449 °C (8075639 °F) Shaders Temperature 1171513530 °C (2108724330 °F) I know this reading is incorrect, because my laptop is nowhere near the surface of the sun and my desk has not burst into flames. When it's opererating normally, I get a sane reading like [Core Temperature 58 °C (136 °F)] with no Shaders Temperature listed. All I have to do to resolve the issue is reboot. I have seen no stability issues with the graphics or anything else. A long time ago, I had an issue with this computer where my framerate would suddenly drop during a 3D game from 40fps to <1fps, but after looking at the temperature readout immediately after quitting a game, I removed the bottom panel and blew the dust out of the vent and heatsink. Since then I have no drops in framerate under any situation. I have uploaded a zip containing the SIW reports for when the problem is occurring and when the computer is operating normally. I don't have a paid account so it can only be downloaded 10 times, so please only download the reports if you think you can use them. If you try to download the reports and they are no longer available, please comment and I will re-upload them. If you want to look at the files, they are on Rapidshare. EDIT It happened again, and I looked a little deeper into the System logs. When this happens, there are a lot of errors about other device drivers unable to start. All of these errors are for PnP drivers. Also, my USB keyboard and mouse take a few moments before they actually start working, although this happens sometimes the first normal boot as well. I am quite sure this is related, so I am adding the pnp tag. Also, CHKDSK will not run on boot. Even if a check is scheduled or a volume is manually set as dirty, CHKDSK will be skipped entirely, not even leaving an entry in the System logs. I tried running CHKNTFS /D, which did not work. I then manually changed my HKLM\System\CurrentControlSet\Control\Session Manager BootExecute value to the default listed on Microsoft's website. That did not work either. I ended up booting to repair mode and running CHKDSK there, which found a number of minor inconsistencies on my system drive, but none on my data drive. I have no idea if this is related. Some more information for those who don't download my SIW report file: Antivirus and Firewall are ESET Smart Security I have three different virutalization programs installed: VMware Player, Windows Virtual PC, and VirtualBox. The network adapters for these show up in the log of failed device starts. EDIT 2 I tried running sfc /scannow, which reported that it found corrupted files that could not be fixed. The CBS log is extremely cryptic. I tried booting to my install disk, launching repair mode, and doing an offline sfc from there, which produced the same result.

• Windows XP Video Configuration Issues

  - by Matt

  Recently I had my motherboard burn out on me. Needing the machine for work, I purchased a different motherboard and installed that. Generally a reinstall of windows is good at that point but I am not in a position to do that so I just decided I would live with it for now. When I can log-in, everything works fine, what doesn't is getting to the log-in prompt to begin with. Basically when I first installed the new mobo, every time I rebooted the machine, I would not get the windows login prompt. One of the monitors would receive a signal but the screen would be black. Moving the mouse would not show the cursor and hitting the up arrow key and typing my password and hitting enter (which will normally log you in without mouse) wouldn't change anything. I would then change the monitor configuration around (2 lcd's and a crt) and reboot and at least one of the monitors would work and display the login prompt. I could then go into display properties and turn on the other monitors. However if I rebooted again, I would get the black screen on one monitor again. I would then have to change the configuration again to one not used before and I could re-do the manual setup at that point. I think windows saves the configurations so I had to keep giving it new ones. Needless to say I've been trying to not turn off my machine. Early this week I actually got the prompt to come up without playing musical monitors. Thinking everything was getting better, I found no harm in rebooting to install the latest windows updates. Boy was I wrong. Now no matter what I do I can't get a windows log-in prompt to display. I've tried almost every conceivable combination. The new mobo has onboard video so I set that in the bios (yea bios screen always displays fine, its not until windows boots that there is a problem) to be the primary video. Still no luck. I have two other graphics cards in the machine which I'm using. Tried all kinds of configurations between those and on-board but still get this black screen of death. I read somewhere that deleting the video drivers would reset the configurations. I logged into safe mode (which works on one monitor), and uninstalled the display drivers. Still no luck and when I booted back into safe mode, it wanted to install new hardware and the display adapters weren't there as expected. Anyone have any ideas? A fresh install would be a pain and I might be getting my old board back from RMA soon so not sure I want to go through with that just yet. Only thing I can think of is to continue to try other combinations like physically removing the graphics cards. They are both EVGA 8600 cards and the windows boot screen does display fwiw.

• Intermittent lockups, unable to diagnose in over a year

  - by Magsol

  Here's a real doosie; I may just give my firstborn child to whomever helps me solve this problem. In July 2008, I assembled what would be my desktop computer for graduate school. Here are the specs of the machine I built: Thermaltake 750W PSU Corsair Dominator 2x2GB 240-pin SDRAM Thermaltake Tower Asus P5K Deluxe Motherboard Intel Core 2 Quad Q9300 2.5GHz CPU 2 x GeForce 8600 GT WD Caviar Blue 640GB hard drive CD burner DVD burner Soon thereafter, I ordered a new motherboard (because I was an idiot; that first motherboard supported CrossFire, not SLI), an Asus P5N-D. I was originally running Windows XP SP3. Pretty much right into the start of the fall semester, my desktop would simply lock up after awhile. If my system was largely idling, it would be after 1-3 days. If was gaming, it often happened an hour or two into my gaming session, indicating a link to activity level. Here's where it started getting interesting. I started looking at the system temps. The CPU was warmer than it should have been (~60s C), so I purchased some more efficient cooling compound a way better cooler for it. Now it hardly goes over 40 C. Intel was even kind enough to swap it out for free, just to rule it out. Lockups continued. The graphics cards were also running pretty warm: about 60 C idling. Removing one of them seemed to improve stability a little bit...as in, it wouldn't lock up quite as frequently, but still always eventually locked up. But it didn't matter which card I used or removed, the lockups continued. I reverted back to the original motherboard, the P5K Deluxe. Lockups continued. I purchased an entirely new motherboard, eVGA's nForce 750i. Lockups continued. Ran memtest86+ over and over and over, with no errors. Even RMA'd the memory. Lockups continued. Replaced the PSU with a Corsair 750W PSU. Lockups continued. Tried disconnecting all IDE drives (HDDs are SATA). Lockups continued. Replaced both graphics cards with a single Radeon HD 4980. Average temps are now always around 50 C when idling, 60 C only when gaming. Lockups continued. Throughout the whole ordeal, the system has been upgraded from Windows XP SP3 to Vista 32-bit, to Vista 64-bit, and is now at Windows 7 64-bit. Lockups have occurred at every step along the way (each OS was in place for at least a few months before the next upgrade). Edit: By "upgrade" I mean clean install each time. In addition to those reformats, I have performed many, many other reformats of the system and a reinstall of whatever OS had been previously installed in an attempt to rectify this problem, to no avail./Edit When the system locks up, there's no blue screen, no reboot, no error message of any kind. It simply freezes in place until I hit the reset button. Very, very rarely, once Windows boots back up, the system informs me that Windows has recovered from an error, but it can never find the source aside from some piece of hardware. I've swapped out every component in this computer, and there are more fans in it than I care to count...though for the sake of completeness: top 80mm case fan (out) rear 80mm case fan (out) rear 120mm case fan (out) front 120mm case fan (in) side 250mm case fan (in) giant CPU fan on-board motherboard fan (the eVGA board) triple-fan memory setup (came with the memory) PSU internal fan another 120mm fan I stuck on the underside of the video card to keep hot air from collecting at the bottom of the case I'm truly out of ideas. ANY help at all would be oh-so-very GREATLY appreciated. Thank you!

• md/raid:md2: cannot start dirty degraded array, kernel panic

  - by nl-x

  After having made use of a remote power switch, my server did not come back online. When I went to the datacenter and reboot the computer on the spot I see the server booting (I see the centos progress bar with running almost all the way to the end) and eventually giving the following messages: md/raid:md2: cannot start dirty degraded array. md/raid:md2: failed to run raid set. md: pers->run() failed ... md/raid:md2: cannot start dirty degraded array. md/raid:md2: failed to run raid set. md: pers->run() failed ... Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init not tainted 2.6.32-279.1.1.el6.i686 #1 Call Trace: [<c083bfbc>] ? panic+0x68/0x11c [<c045a501>] ? do_exit+0x741/0x750 [<c045a54c>] ? do_group_exit+0x3c/0xa0 [<c045a5c1>] ? sys_exit_group+0x11/0x20 [<c083eba4>] ? syscall_call+0x7/0xb [<c083007b>] ? cmos_wake_setup+0x62/0x112 The server runs CentOS and has software raid, and I don't have backups of the raid settings. The only backup I have is of /home and the database dumps. (Glad to at least have those though.) Since the server is an old Dell PowerEdge 1750 with no CD-ROM drive, I have no way of booting the machine from a boot disk. I also remember in the past that the server also wouldn't boot from a bootable USB disk. So the only way I know how to boot the server is to go to the datacenter, pick up the server and take it to the office. Screw open the server. Attach a cdrom drive to an IDE slot on the motherboard. And then boot it. I am hoping you guys could help me avoid this. I have looked a bit through the boot options and I found the following boot options. When CentOS is about to boot and interrupt the boot-countdown: CentOS (2.6.32-279.1.1.el63.i686) CentOS Linux (2.6.32-71.29.1.el6.i686) centos (2.6.32-71.el6.i686) I think the first configuration is the default one, because choosing that gets me to the above mentioned kernel panic. The other ones end with something like "Sleeping forever". I can press 'e' to edit boot commands, press 'a' to modify kernel arguments and press 'c' for grub command line. The command line gives a grub prompt. But I have no idea how to get the system to boot without (trying to) access the dirty partitions. What I want to do is off course: - boot the machine - check hard drive for errors - mark the drive as clean

• How to delete files and folders that cannot be deleted?

  - by glenneroo

  I have a backup copy of a previous Windows' Documents and Settings folder which only contains my original user and within 2 more directories: Favorites and Local Settings. When I try to delete Local Settings I get this error: When I try to delete Favorites, I get this error: I ran this in a cmd shell: attrib *.* -r -a -s -h /s ...but it did not help, nor did it return any errors/warnings. I used Unlocker v1.8.5 and LockHunter repeatedly at multiple levels to see if any files are in use, but both always say: No Files Locked. Update #1: I was able to rename the directory, which now gives me this warning before (trying to) delete: If I press Yes (or Yes to All) then I get this error: Update #2: I let chkdsk /f run which required a reboot since it's on my primary system partition. During Stage 2 scanning, I received about 40 of these: Deleting an index entry from index $0 of file 25. ...followed by: Deleting index entry cookies in index $I30 of file 37576. ...but I still get the first error dialog above when trying to delete. I ran chkdsk again, this time: chkdsk /f /r. Produced no messages. Same result when deleting. Update #3: Digging deeper, the 99 is the name of one of many directories located deep in here: C:\Documents and Settings.OLD\User\Local Settings\Application Data\Microsoft\Messenger\[email protected]\SharingMetadata\[email protected]\DFSR\Staging\CS{D4E4AE55-B5E2-F03B-5189-6C4DA6E41788}\ Inside each of those directories were files with names such as: 2300-{C93D01AC-0739-4FD9-88C7-13D2F21A208E}-v2300-{C93D01AC-0739-4FD9-88C7-13D2F21A208E}-v2300-Downloaded.frx I noticed that, unlike all the directories, I couldn't rename any of these files. I also noticed that the file + dir names were extremely long: Original directory = 194 characters Filenames = 100+ characters Together the length exceeds the 255-char limit which is bad and would explain the error message I posted in Update #1. Partial Solution: Rename all directories until the total path length is less than 100. Afterwards I was able to rename the .frx files, not to mention delete everything inside the Local Settings directory. This is only a partial solution because these (empty) directories are still not deleteable, C:\1\2\Favorites\Wien\What To Do.. C:\1\2\Favorites\Photography\FIRE Same error as above: Here is what Explorer properties shows for both folders: Update #4 (another partial solution): Using harrymc's answer combined with thoroughly reading through this amazing MS-KB article which contains nearly everyone's idea and then some, inconspicuously titled: You cannot delete a file or a folder on an NTFS file system volume. I was able to delete the 2nd folder C:\1\2\Favorites\Photography\FIRE - the problem being that there was an invisible trailing space at the end. I got lucky when I did an auto-complete whilst playing around with the del "\\?\<path>" command which he suggested. NOTE: A normal del did NOT work, nor did deleting from explorer. Now all that is left is the first directory C:\1\2\Favorites\Wien\What To Do.. (yes I tried endlessly with multiple combinations of the above solution ;) Keep 'em coming! =)

• How to diagnose and solve an erratic "HDCP Support Required"?

  - by Jom Orgstrom

  I am playing a digital tv broadcast on Windows Media Center for Windows 7. I built this system so it works with HDCP, and in fact I have been able to watch tv and bluray before with this same computer. However, I suddenly started getting an "HDCP Support Required" error from WMC. The entire message is as follows: HDCP Support Required High-bandwidth Digital Content Protection (HDCP) may not be supported by the current video card. Use an HDCP-compliant display, video card, and video driver. Or, connect using an analog connection such as component or VGA. Relevant specs are: CPU: Ivy Bridge Core i7-3770 Motherboard: Asus P8H77-I Memory: 16GB DDR3-1600 Graphics: Radeon HD 7850 (Driver by AMD, version 8.982.0.0 built on 2012/07/27) Display: Acer P243w connected by HDMI Sound: Roland Quad-Capture (It complains even when I use the bundled VIA HD Audio) TV Tuner: I-O Data GV-MC7/HZ3 OS: Windows 7 Professional SP1, Windows Update enabled. All patched and up to date. As you can see, there is nothing weird or old about my setup. I am also not doing anything strange, not doing any overclocking, weird system changes and so on. One thing that does happen from time to time, is that the display goes black for a few seconds (sometimes when watching media contents, sometimes when just using photoshop or Visual Studio). This happened with my previous setup as well, so I'd be inclined to think it is a display or cable issue (apart from the BD drive, these are the only things I kept from my previous setup to this one). But being a digital transfer, as far as I know, these things either work or not. Never erratically or with decreased quality. The thing is that sometimes I can watch the TV, sometimes not. This happens with recorded programs as well, so it's not a per-program thing. Sometimes rebooting helps, sometimes it doesn't. Sometimes unplugging and plugging back the HDMI connector helps, sometimes it doesn't. Sometimes doing so doesn't even turn the screen back on, so I have to reboot. Unfortunately, WMC's error message is quite unhelpful. I'd like to know exactly where the problem is, so I can solve it. I don't want to buy a brand new display just to then find out it was a registry setting that was misconfigured. I've tried looking at the system event viewer, but these errors don't show up at all in there. Other people who have this problem seem to have a setup that is not HDCP compliant, so I turn to you guys here. Anybody knows how to diagnose this problem? Edit: So I got the Cyberlink Blu-ray disc advisor. I ran it and told me everything was okay, except for the Video Connection Type, which showed as "Digital (without HDCP)". I then proceeded to unplug the power cable from the monitor, plugged it in again, ran the tool again, and now it's "Digital (with HDCP)". Needless to say, I can watch my TV and recorded programs on WMP again. I'm guessing that at some point, something may be slightly wrong with the HDCP setup, and Windows decides to reset the entire content protection path (which leads to the screen blanking out). Usually the reset succeeds, but sometimes it doesn't, so Windows defaults to turning HDCP off. There's no way to turn it back on, except by doing a hard reset of the display. I really want to know what the exact error was, so I can fix it. Is it the cable? is it the display? is it the video card? the driver? Also, is there any other way to try and turn HDCP on again without having to hard reset the display? Oh, questions, questions...

• Windows Service SearchIndexer.exe Crashes on Indexing

  - by Josh Jay

  Relevant Specs: Windows 7 Professional 64-bit SP1 Outlook 2010 Version 14.0.7116.5000 (32-bit) Original Symptom: In outlook, I attempted to search for an email but nothing ever returned and the indicator kept going like it was searching. Attempted Resolutions: I investigated the search options and with some research noticed the Windows Service "Windows Search" (SearchIndexer.exe) was not running. I attempted to start it but I receive this error message: "Windows could not start the Windows Search service on Local Computer. Error 1067: The process terminated unexpectedly."

• File server share access intermittent/slow/machine unstable: win2k8r2

  - by Jack B.

  I have a file server running Win2k8R2 on an older HP DL380G4. It has nothing set up on it other than file sharing. All drivers/firmware/updates installed. The file server is used as a dump for a bunch of test machines - so essentially a lot of small files are being written to it. It was working fine until it started showing the following symptoms: Shares became either very slow/intermittent or could not access them at all. Logging in the the server, you could use it like normal but windows would start freezing and eventually you had to hard reboot it because nothing was responsive. After rebooting, it would work fine for 20min-2hours and then degrade into this broken state again. Some info after investigation: HP Raid Config utility shows the Raid array as functioning properly (RAID5 btw). Event log shows a bunch of DoS attacks from the test machines, saying it has disconnected the connection a. AFAIK (not part of my job) the test machines haven't changed the way they log information to this server or the amount of them hasn't increased. b. Nothing is infected, this server was scanned fully, and the test machines are re-imaged almost daily. Nothing in performance monitor shows as anything being pegged at maximum (CPU/HD/Network/RAM) I installed MS Network Monitor and it is showing a lot of traffic The server was using one gigabit Ethernet connection, I connected the second one as well with the same results. Forgot to add - one of the commonly written to dirs on the share has over 16k subdirs in it, with a crapton of small files within those dirs. Some of the OS instability was slow access to the drive which has this directory - perfmon doesn't show much activity on the HD though so I'm not sure if this crowded dir is the cause. Here is one important fact: I ran into this issue 2-3 months ago, couldn't figure it out, but I had a spare identical machine so I swapped them out (thought it was related to the machine), and now I have the same issue. Also, the computer will be stable if I turn off file sharing. So is the server just getting DoS'd by the test machines? I've never dealt with such an issue. Is instability in the server's OS common when getting DoS'd? Is there anything I can do to confirm this before telling the owners of the test machines to optimize their traffic? (I'm not sure what they'll be able to do). Is there something within Win2k8R2 that can balance the traffic across the two NICs? Any help would be appreciated. Update: Another thought - the drive with the share is RAID5 across 6 SCSI320 300GB HDs. They are near full capacity about 100GB from 1TB left. Could the amount of tiny files could be causing some weirdness with the parity in this array? I think I've read something about this in the past but I'm no expert on RAID.

• Hour-long shutdown duration "shutting down hyper-v virtual machine management service"

  - by icelava

  I have a Windows 2008 R2 server that is a Hyper-V host (Dell PowerEdge T300). Today for the first time I encountered an odd situation; i lost connection with one of the guest machines but logging on physically it seems the guest OS is still running but no longer contactable via the network. I tried to shut down the guest machine (Windows XP) but it would not shut down, getting stuck in a "Not responding" dialog box that cannot be dismissed. I used the Hyper-V management console to reset the machine and it could not get out of resetting state. I tried to save another Windows 2003 guest machine, and it would be progress with its Saving state (0%). The other running Windows 2003 guest was stuck in the logon dialog. My first suspicion is perhaps one of the Windows update patches this week (10 Nov 2011) may something to do with it, which was still pending a system restart. Well, since I could not do anything with Hyper-V i proceeded with the Windows Update restart, and now it is stuck half an hour at "Shutting down hyper-v virtual machine management service" Prior to restarting I did not observe any hard disk errors reported in the system event log; doubt it is a disk-related condition. Shall I force a hard reboot? UPDATE Ok so i left it hanging over an hour while attending to other matters, and thankfully the host cleanly restarted. I can operate the guest machines fine now. Phew. Hyper-V must have been crawling for some reason. The VMs have been observed to become slow in the past when the host has been up for a long duration (two weeks to a month), but never this slow. Would love to know what types of performance monitoring items i can observe to give a hint why this can happen. UPDATE 2012-02-13 In the months ever since, Hyper-V has stalled into this state another two times. It appears so randomly and without any error event logs to hint what is causing it enter this "drunkard" state. Just an Hyper-V management service timeout. Log Name: System Source: Service Control Manager Date: 13/2/2012 9:16:48 AM Event ID: 7043 Task Category: None Level: Error Keywords: Classic User: N/A Computer: elune Description: The Hyper-V Virtual Machine Management service did not shut down properly after receiving a preshutdown control.

• Where's my memory?! Nginx + PHP-FPM front end webserver slows to a crawl...

  - by incredimike

  I'm not sure if I have a problem with a memory leak (as my hosting company suggests), or if we both need to read http://linuxatemyram.com. Maybe you clever people can help us out? This is a front-end webserver VM running essentially only nginx & php-fpm on RHEL 5.5. This server is powering Magento, a PHP eCommerce thinggy. The server is running in a shared environment, but we're changing that soon. Anyway.. after a reboot the server runs just fine, but within a day it will grind itself into nothingness. Pages will take literally 2 minutes to load, CPU spikes like crazy, etc.. The console is even sluggish when I SSH in. It's like my whole server is being brought to its knees. I've also been monitoring the DB server via top and tcpdumping incoming traffic. The DB stays idle for a good portion of that "slow" load time. When i start seeing queries coming from the front-end server, the page loads soon afterward. Here are some stats after me logging in during a slow-down, after restarting php-fpm: [mike@front01 ~]$ free -m total used free shared buffers cached Mem: 5963 5217 745 0 192 314 -/+ buffers/cache: 4711 1252 Swap: 4047 4 4042 [mike@front01 ~]$ top top - 11:38:55 up 2 days, 1:01, 3 users, load average: 0.06, 0.17, 0.21 Tasks: 131 total, 1 running, 130 sleeping, 0 stopped, 0 zombie Cpu0 : 0.0%us, 0.3%sy, 0.0%ni, 99.3%id, 0.3%wa, 0.0%hi, 0.0%si, 0.0%st Cpu1 : 0.3%us, 0.0%sy, 0.0%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu2 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu3 : 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 6106800k total, 5361288k used, 745512k free, 199960k buffers Swap: 4144728k total, 4976k used, 4139752k free, 328480k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 31806 apache 15 0 601m 120m 37m S 0.0 2.0 0:22.23 php-fpm 31805 apache 15 0 549m 66m 31m S 0.0 1.1 0:14.54 php-fpm 31809 apache 16 0 547m 65m 32m S 0.0 1.1 0:12.84 php-fpm 32285 apache 15 0 546m 63m 33m S 0.0 1.1 0:09.22 php-fpm 32373 apache 15 0 546m 62m 32m S 0.0 1.1 0:09.66 php-fpm 31808 apache 16 0 543m 60m 35m S 0.0 1.0 0:18.93 php-fpm 31807 apache 16 0 533m 49m 30m S 0.0 0.8 0:08.93 php-fpm 32092 apache 15 0 535m 48m 27m S 0.0 0.8 0:06.67 php-fpm 4392 root 18 0 194m 10m 7184 S 0.0 0.2 0:06.96 cvd 4064 root 15 0 154m 8304 4220 S 0.0 0.1 3:55.57 snmpd 4394 root 15 0 119m 5660 2944 S 0.0 0.1 0:02.84 EvMgrC 31804 root 15 0 519m 5180 932 S 0.0 0.1 0:00.46 php-fpm 4138 ntp 15 0 23396 5032 3904 S 0.0 0.1 0:02.38 ntpd 643 nginx 15 0 95276 4408 1524 S 0.0 0.1 0:01.15 nginx 5131 root 16 0 90128 3340 2600 S 0.0 0.1 0:01.41 sshd 28467 root 15 0 90128 3340 2600 S 0.0 0.1 0:00.35 sshd 32602 root 16 0 90128 3332 2600 S 0.0 0.1 0:00.36 sshd 1614 root 16 0 90128 3308 2588 S 0.0 0.1 0:00.02 sshd 2817 root 5 -10 7216 3140 1724 S 0.0 0.1 0:03.80 iscsid 4161 root 15 0 66948 2340 800 S 0.0 0.0 0:10.35 sendmail 1617 nicole 17 0 53876 2000 1516 S 0.0 0.0 0:00.02 sftp-server ...

• RAID controller dropping the wrong drive

  - by bramp

  I've been having an issue with 3ware 9500S-8 RAID 10, and I have contracted their tech support, but I wanted to hear the serverfault community's recommendations. Firstly, all my data is backuped and secure, so I don't mind blowing my RAID away if I have to. But let me describe the problem I've been seeing. A month ago, disk 6 dropped out of the RAID. It is mirrored with disk 7, so I wasn't that bothered. I went to the data centre and replaced it. When I got back to the office, I noticed that disk 6 will still not in the RAID, and in fact the controller was show the name of the old drive still. A week later I went back and replace the drive again, thinking I might have swapped in a bad drive. Still the same problem. I decided to reboot the machine, to see if that would "force" the controller into seeing the new drive. It did, and a rebuild started to happen (from disk 7). Eventually both drives were showing as good. A week later, the MySQL database has flagged the database is corrupt, and is unable to repair it. I don't know what has gone wrong, but I suspected this 6-7 pair. At this point I noticed that the RAID had constantly been verifying itself, over and over. Regardless of this I began to rebuild the database, which took about 19 hours. It's a big database. Near the end of the repair, the RAID controller told me it had dropped disk 7, and that some data was most likely corrupted. I contacted LSI tech support, and they very promptly started to help me. I mentioned that drive 7 had been dropped. They suspect that drive 7 was always at fault, and drive 6 had always been good. I want to know how often a RAID controller would drop the wrong drive (in this case dropping drive 6 a month ago, instead of 7). I foolishly didn't run smartctl on the drives before I started swapping them out. I just assumed the RAID controller knew what it was talking about. I think my plan of action is to replace drive 7, rebuild the array from scratch, double check smartctl on ALL the disks, and then start restoring my data again. I would appreciate anyone's input on what the correct procedure for swapping drives is, and how often failures like this happen. If anyone would like more information then I'd be happy to provide it. thanks in advance. Oh some more information. I'm running CentOS 5.3, with two RAID arrays, a simple RAID 1 for the OS, and RAID 10 for the database. Both arrays are on different controllers. The RAID 10 is made of 10 identical ST3640323AS drives, until I swapped in a SAMSUNG HD103SJ last month.

• How to diagnose computer lockups and freezes?

  - by Scott Mitchell

  I built a desktop computer a couple years back with the following specs: CPU: Intel Core 2 Quad Q9300 Yorkfield 2.5GHz 6 MB L2 Cache LGA 775 95W Quad-Core Processor BX80580Q9300 Motherboard: EVGA 122-CK-NF68-T1 LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard Video Card: Two EVGA 256-P2-N758-TR GeForce 8600GT SCC 256 MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card PSU: SeaSonic S12 Energy Plus SS-550HT 550W ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply Memory: Two G.SKILL 4 GB (2 x 2 GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ Since its inception, the machine has periodically locked up, the regularity having varied over the years from once a day to once a month. Typically, lockups happen once every few days. By "lockup" I mean my computer just freezes. The screen locks up, I can't move the mouse. Hitting keys on my keyboard that normally turn LEDs on or off on the keyboard (such as Caps Lock) no longer turn the LEDs on or off. If there was music playing at the time of the lockup, noise keeps coming out of the speakers, but it's just the current frequency/note that plays indefinitely. There is no BSOD. When such a lockup occurs I have to do a hard reboot by either turning off the computer or hitting the reset button. I have the most recent version of the NVIDIA hardware drivers, and update them semi-regularly, but that hasn't seemed to help. I am currently using Windows 7 x64, but was previously using Windows Server 2003 x64 and having the same lockup issues. My guess is that it's somehow video driver or motherboard related, but I don't know how to go about diagnosing this problem to narrow down which of the two is the culprit. Additional information re: cooling Regarding cooling... I've not installed any after-market cooling systems aside from two regular fans I scavenged from an older computer. The fan atop the CPU is the one that shipped with it. One of the two scavenged fans I added it located at the bottom tower of the corner, in an attempt to create some airflow from front to back. The second fan is pointed directly at the two video cards. SpeedFan installation and readings Per studiohack's suggestion, I installed SpeedFan, which provided the following temperature readings: GPU: 63C GPU: 65C System: 76C CPU: 64C AUX: 36C Core 0: 78C Core 1: 76C Core 2: 79C Core 3: 79C Update #3: Another Lockup :-( Well, I had another lockup last night. :-( SpeedFan reported the CPU temp at 38 C when it happened, and there was no spike in temperature leading up to the freeze. One thing I notice is that the freeze seems more likely to happen if I am watching a video. In fact, of the last 5 freezes over the past month, 4 of them have been while watching a video on Flickr. Not necessarily the same video, but a video nevertheless. I don't know if this is just coincidence or if it means anything. (As an aside, each night before bedtime my 2 year old daughter sits on my lap and watches some home videos on Flickr and, in the last month, has learned the phrase, "Uh oh, computer broke.") Update #4: MemTest86 and 3DMark06 Test Results: Per suggestions in the comments, I ran the MemTest86 overnight and it cycled through the 8 GB of memory 5 times without error. I also ran the 3DMark06 test without a problem (see my scores at http://3dmark.com/3dm06/15163549). So... what now? :-) Any further suggestions on what to check? Is there some way to get a stack trace or something when the computer locks like that? Resolution I have never did figure out the particular problems, but based on the suggestions here and elsewhere, I'm presuming it was a motherboard issue. In any event, I recently upgraded my system, buying a new motherbeard, PSU, CPU, and RAM, and that new rig has been working splendidly the past several weeks. I am using the same graphic cards as in the old setup, so I think it's safe to reason that they weren't the cause of the problem.

• Installing XP through USB-flash disc

  - by Crazy Buddy

  I don't know whether this could be asked here... So, Pardon me for this. Probably, this is based on My laptop and a contradiction to this question asked already here... I tried to format my "government-provided" laptop (No CD-drive). I thought those IT guys are proving that they're too smart..! I have the Windows XP CD right now. I didn't like to stick with some home-made OS from our Government. So, I used another laptop to format the govt. thing and tried to install XP (As I didn't have enough bills to invest on Windows 7 or 8). Case 1: First, I allowed WinSetupFromUSB 1.0 beta 8 to deal with the flash disk. I wondered for the first time that XP text-screen appeared. Using the first part, I formatted my laptop. It started to copy files, entered into the next part, and completed the installation. I started my PC for the first time. XP splash screen appeared. Suddenly, a blue screen flashed and disappeared (I can't even read what it says). Rebooted and arrived at the screen, "Start Windows Normally". It happens and happens still - like an infinite loop :-) Case 2: Next, I used Rufus 1.2.0 to transfer files to my Flash and it screwed everything out. Even if I used Flash to boot, it arrives to the same screen "Start Windows normally". It doesn't show any response of Flash being inserted. Then I recognized that, It's simply copies everything to the flash disk. Case 3: Then, I started with Novicorp WinToFlash (giving utmost priority to this site). I booted with the disk. I entered into the first part - "Text mode". Some lines started running like that "Press F6 if you..." like that. The last thing I saw was, "Setup is starting Windows..." Suddenly a blue screen appeared like this captured one. I've a suspicion that the same screen appears again & again in first case. Man, I'm dead. Case 4: For the sake of my last hope, I used WinSetupFromUSB 0.1.1. I was shocked on arriving at a screen which says something "GRUB4DOS" like that and some commands like {command line, reboot, halt, \find menu.lst} and when I go inside those "find" options, I see "Error:15 - File not found". Googling provided some commands to mount SETUPLDR.BIN file in the "grub" thing which also proved unsuccessful... Some sites say that Factory reset uses only some function keys. A guy said that it's F11 for lenovo. Screw him. It's all a waste-of-time. But, I think SE would help me out. Is our government IT guys doin' this to me? Are they Soooo smart to spark some blue screen in front of me to freak me out? Any suggestions or new (useful) USB transferring things would be appreciated. It's very urgent. So, It'd be better if you guys pay some attention in debugging and help me out..? Thanks for your time guys :-)

• Windows 8.1 Update 1 Disk Usage 100%

  - by Gookjin Jeong

  Background Information / Computer Specs I have a 14-inch Samsung Series 5 Ultra. Core i5 CPU, 750GB HDD, 8GB RAM, Intel HD Graphics 4000. I've had the computer for about 1.5 years with no major problems. Problem The issue appeared at the beginning of April this year, when I updated the OS to Windows 8.1 Update 1 (not from 8 to 8.1). After being on continually (except for at night, when I put it on sleep mode) for about 48 hours, the disk usage as seen by Task Manager hits 100%. When this happens, everything from opening/closing applications to typing and even bringing up the start screen by pressing the Windows key becomes extremely slow. The only way to make the disk usage decrease is to restart the computer. Then the problem repeats. I've used my current laptop (as well as my previous laptops) this way -- putting it on sleep mode at night and restarting it only when Windows needs to install updates -- for a long time. So I know the 100% disk usage is not due to the way I use the computer. The thing that causes the spike varies. Sometimes it's System, sometimes it's one of the various applications I installed (e.g. Chrome, Evernote, Spotify, Wunderlist, iTunes, etc.), and sometimes it's Antimalware Service Executable, etc. Tried Solutions I think I tried almost every solution out there for this problem: Running the check disk command (chkdsk /b /f /v /scan c:) from Admin Command Prompt Running Windows Memory Diagnostic Disabling Superfetch and Windows Search from services.msc Running "Fix problems with Windows Update" from Control Panel -- Troubleshooting Updating and rolling back the graphics driver (Intel HD 4000) Disabling "Use hardware acceleration when available" from Chrome settings Disabling Intel Rapid Storage Technology Running the SFC /SCANNOW command as recommended here Running a quick scan & a full scan from Windows Defender (no threats found) Taking the hard drive out and putting it back Refreshing the computer, from the Update and recovery -- Recovery option in Windows settings NONE of the above worked for me. I was about to give up but then noticed that one of the main culprits of the disk usage spike, as shown in the "Disk Activity" section of the Resource Monitor, was C:\System (pagefile.sys). I googled around and found that one of the recommended solutions was to disable pagefile. I then went to **Control Panel -- System and Security -- System -- Advanced system settings -- Advanced tab -- Performance settings -- Advanced tab -- "Change" under Virtual memory and discovered that the number for "Currently allocated" at the bottom was 1280MB, although the number for "Recommended" was 4533MB. I immediately changed it to 4533MB and checked my family members' computers to see what the numbers were like. All of theirs had a currently allocated space that was only slightly smaller than the recommended space. See screenshot below: This might fix the problem. I'll have to wait a couple more days.But if it doesn't, what in the world should I do next? I'm guessing the hard drive isn't failing because This computer is less than 2 years old; and Speccy says that the status of the HDD is good. Update 5/27/2014 The "4533MB" solution did not work. I had to reboot the computer about 30 minutes ago because the disk usage again hit 100%. When I opened Resource Monitor the C:\System (pagefile.sys) again was shown to be the culprit. I have now disabled pagefile entirely via the same window shown above in the screenshot. The number for "currently allocated" is now 0MB. Will update again in a couple days, or if the problem occurs again, whichever comes sooner.

• File server share access intermittent/slow/machine unstable: win2k8r2

  - by Jack B.

  I have a file server running Win2k8R2 on an older HP DL380G4. It has nothing set up on it other than file sharing. All drivers/firmware/updates installed. The file server is used as a dump for a bunch of test machines - so essentially a lot of small files are being written to it. It was working fine until it started showing the following symptoms: Shares became either very slow/intermittent or could not access them at all. Logging in the the server, you could use it like normal but windows would start freezing and eventually you had to hard reboot it because nothing was responsive. After rebooting, it would work fine for 20min-2hours and then degrade into this broken state again. Some info after investigation: HP Raid Config utility shows the Raid array as functioning properly (RAID5 btw). Event log shows a bunch of DoS attacks from the test machines, saying it has disconnected the connection a. AFAIK (not part of my job) the test machines haven't changed the way they log information to this server or the amount of them hasn't increased. b. Nothing is infected, this server was scanned fully, and the test machines are re-imaged almost daily. Nothing in performance monitor shows as anything being pegged at maximum (CPU/HD/Network/RAM) I installed MS Network Monitor and it is showing a lot of traffic The server was using one gigabit Ethernet connection, I connected the second one as well with the same results. Forgot to add - one of the commonly written to dirs on the share has over 16k subdirs in it, with a crapton of small files within those dirs. Some of the OS instability was slow access to the drive which has this directory - perfmon doesn't show much activity on the HD though so I'm not sure if this crowded dir is the cause. Here is one important fact: I ran into this issue 2-3 months ago, couldn't figure it out, but I had a spare identical machine so I swapped them out (thought it was related to the machine), and now I have the same issue. Also, the computer will be stable if I turn off file sharing. So is the server just getting DoS'd by the test machines? I've never dealt with such an issue. Is instability in the server's OS common when getting DoS'd? Is there anything I can do to confirm this before telling the owners of the test machines to optimize their traffic? (I'm not sure what they'll be able to do). Is there something within Win2k8R2 that can balance the traffic across the two NICs? Any help would be appreciated. Update: Another thought - the drive with the share is RAID5 across 6 SCSI320 300GB HDs. They are near full capacity about 100GB from 1TB left. Could the amount of tiny files could be causing some weirdness with the parity in this array? I think I've read something about this in the past but I'm no expert on RAID.
