• Proper approach to debug PC startup problems (POST)

  - by saurabhj

  My CPU was heating up to around 65 deg C and last time this had happened (about a year ago), I got thermal paste put between the CPU and heat sink and this managed to get it down to about 45 - 50 degrees. This time, I got some thermal paste and put it myself. However, my PC is not showing the POST display and not starting up. This is what happens LEDs light up HDDs spin Mouse is getting power All fans including the processor fan starts No display on monitor No diagnostic beep sounds (no sounds at all) What I have tried Removing everything including RAM, HDD, PCI cards, AGP card Boot up machine No changes from first state. What steps can I take to figure out where the problem lies? Note (might be important) When I removed the heat sink, the processor came out with it (it was stuck to it inspite of the processor latch on) Had to pry it separate with a screw-driver. Configuration Pentium 4, 2.8 Ghz with HT (very old, I know) Original Intel Mobo with onboard sound and graphics (GB series) 2x512 Mb DDR-RAM 2 SATA disks (320 Gigs / 250 gigs) DVD Writer Creative Sound Card Network card Any help would be appreciated. Thanks!

• HP DL380 G3 2U For Basic Web Server in 2012

  - by ryandlf

  I have an opportunity to pick up a used HP DL380 G3 2U for $100. I'm looking for a basic entry level web server that I can host a small - medium size website on and more or less learn the ins and outs of running my own web server before I bite the bullet and spend a couple grand on a server. The specs are: Dual (2) Intel Xeon 2.4GHz 400MHz 512KB Cache 4GB PC2100 ECC Registered Memory 6 x 72GB 10K U320 SCSI Hard Drives Smart Array 5i RAID Controller Redundant Power Supplies DVD/Floppy, Dual Intel GB NIC's, USB Or would I be better off spending a couple hundred bucks on something like: this new HP Seems like the only major difference is SATA and a bit of storage, but I will likely be implementing a separate storage system of some sort anyways. I guess it also wouldn't hurt to mention that I plan on running a linux server distro, so would the hardware be likely to support linux with a system that is 4 generations old? I don't mind spending a couple hundred extra dollars if its a better solution, but as mentioned previously I am simple looking for a server to learn on and probably use for a year or so while I put together a small - medium size website.

• Active Directory server down, recovering without reinstalling

  - by whatever

  My Windows 2003 server suddenly ceased to function as a DC (this server is the only DC of the domain). All AD related services are down. The only way I can login to the AD is physically to the machine. Everytime I access an AD-related service (e.g. "AD users and computers") I get the below error: Naming information cannot be located because: The specified directory service attribute or value does not exist. Contact your system administrator to verify that your domain is properly configured and is currently online. I found the below system event which matches the time when the issue started, this re-occurs everytime I reboot the server. NTDS General | Global Catalog | Active Directory was unable to establish a connection with the global catalog. Additional Data Error value: 1355 The specified domain either does not exist or could not be contacted. Internal ID: 3200d33 I started the troubleshooting with DNS. Netdiag throws the below error although I think this is simply a consequence of not being able to access the Global Catalog. The procedure entry point DnsGetPrimaryDomainName_UTF8 could not be located in the dynamic link library DNSAPI.dll. Anyway DNS seems OK because I can ping the DC FQDN from the DC itself. I found the below solution which is supposed to help by doing some cleanup of the metadata: http://support.microsoft.com/kb/216498 If I follow procedure 1 here is what I get at step 9: no current site Domain - DC=<mydomain>,DC=<com> no current server no current naming context I can continue the procedure until step 14. I haven't tested step 15 as my understanding is that I will have to reinstall the whole AD again. Is there any way I can recover my AD from there without having to reinstall the whole thing? Update: Yes, the server was powered off/on because reboot would take forever (not because I thought power cycling the unit would fix it more than a reboot).

• After RAID failure SBS 2008 issues logging in and Exchange store does not mount

  - by Josh R

  today has been one of those days. Yesterday a hard drive in our Dell Poweredge 2900 server failed and the RAID array didn't degrade gracefully, so I called Dell (Server still under warranty) and got an engineer to work though the RAID issues with me. He was a nice guy but didn't do too much. We tried to put the RAID in a state where it was bootable and even though we only lost one disk there are still issues with the server. Once we got the server to boot there was an error message saying that the logonui.exe was corrupted and we needed to run chkdsk. I clicked through the error messages and the login screen never came up. So I power cycled the server and it chkdsk automatically but the login screen didn't appear. I tried safe mode, no difference there either. So the issues I am currently having are: 1) The server boots up, the loading windows screen comes up then it dumps me into a black screen where I can only see my mouse cursor. Ctrl+Esc doesn't work Ctrl+Alt+Del doesn't work 2) Some of the services come up: DHCP, DNS, DFS, and Print come up 3) The exchange information store and transport service don't start - I tried using mmc to connect to services.msc on the computer and start them but they throw an error message of "Can't start because group or dependency failed" Has anyone had a problem like this? Can anyone offer some guidance? Thanks a bunch!

• Stop Windows 7 from accessing or writing to hard drive unless "told" to by me? (More info inside...)

  - by Jeff

  A confusing question, perhaps, but bear with me. I have two internal HDDs set up in a RAID0 array which I use as mass storage. I access the drive very infrequently (once a day at most) and so I have set up Windows 7's power options to turn off idle disks after only 1 minute. This is fine, and the disks are turned off most of the time. However, I notice that Windows sometimes spins up the drives when I really, really don't want or need it to. This causes a 30 second delay as both drives spin up and lock up my system. Some examples of when this happens: 1) When I'm installing something using Windows Installer or Installshield; it seems to me as if they're using the drive with most available free space as the installer cache location... so my big RAID drive has to spin up! Most annoying. 2) Apparently, when I open a Java-based program which resides on my system drive and has nothing to do with my RAID drive! 3) At boot-up and shut-down time. At shutdown the drive spin up only for the computer to immediately shut down! Incredibly frustrating! I've already tried changing the letter of the drive, and at some points have removed the drive letter entirely, which solves the first two issues above. So my question (FINALLY!) is this: is there any way I can mark this drive as being for "storage only", so Windows basically does not see it at all until I actually invoke it somehow? Or is there any way I could set it up so that only specific programs have write access to it? For example, download managers, TeraCopy, etc. etc.? Basically I want it to be a "ghost drive" until I'm ready to use it and to stop Windows from spinning it up all the damn time! Thank you. :)

• Sudden "No Signal" in HDMI-DVI connection

  - by nazikus

  Yesterday I have connected external display Asus VW192C to my laptop Dell XPS 14-L421X via HDMI-to-DVI-D cable. And it worked perfectly fine from start. The day after, Asus screen went blank showing "No signal". Every time I connection/disconnection cable or power off/on the display it says "No signal". And I didn't change any system configurations meanwhile. To troubleshoot the problem, I have tried to connect laptop to TV (hdmi-to-hdmi) - it was fine. I've tried to connect a different laptop to the display via the same cable - worked fine as well. So its obviously something on system level, either Windows or graphics drivers. Also it seems that Windows still see the external display (I can move mouse pointer away from the main screen in Extended mode), but there's just no signal. Any ideas? What else to try? PS. My laptop has 2 graphics cards - GeForce 630M and Intel HD 4000 using NVidia Optimus technology. I have updated to latest Intel and NVidia drivers, still didn't help. PPS. Although I shouldn't have updated (from Intel support): "our Intel generic graphics drivers from the Intel website do not support using both Intel Graphics 4000 and NVidia GeForece GT630M". Nevertheless, it should not affect connectivity to additional display.

• Linksys SFE2000 Interface

  - by boburob

  I have a real problem with a layer 3 Linksys switch. First, every time it looses power, it seems to reset back to an older config. Not only this, but when this happens it looses interface settings on one subnet. This would not be a problem but I am completely unable to get to the interface on the working side. It allows me to log on and then just displays a blank screen. I have tried this on: IE6 IE7 IE8 IE9 Firefox 3.5 Opera Chrome All with the same results, except for Opera, which loads half the interface but nothing I can really use. I really need to get onto this switch so I can sort out routing and VLAN tagged ports, so if anyone has any ideas on either of these issues please let me know ASAP! Thanks! Also, due to its location and my lack of laptops with serial connections I cannot putty into it. UPDATE: Looked into this a bit more and it looks like this model of switch does not save the current config to boot unless you make sure to save it yourself, which explains the first issue, however the broken interface is more worrying!

• Ethernet cable unplugged after updating from windows 8.0 to 8.1

  - by Pehmolelu

  Yeah, so I went and updated my windows 8 pro to 8.1. Now everything else seems to work but the network. The Ethernet just says that Network cable is unplugged, even though it is plugged and I have tried different cord as well and I have tested that the router works. I have tried uninstalling the network drivers (Realtec PCIe GBE) and reinstall them with no success. After installing drivers the Device Management gives error for it "Device could not be started. Code 10" Before 8.1 update I had rt630x64.inf, after update it was netrt630x64.inf, and after installing the latest driver rt630x64.inf. With rt630x64.inf there isn't any error, but it's still not just working. New downloaded version: 8.020.0815.2013 (From Realtek website) The driver before: 8.1.510.2013 (After updating the windows to 8.1) I'm using Desktop PC, no VM. I dont have VirtualBox or Vmware installed. I have checked from BIOS that the card is enabled. I have booted in safe mode with network enabled. Says unplugged there as well. I have put the power off for few minutes and put back on, no effect. If anyone has any kind of suggestions, please tell.

• after building in more ram, bios/debian does nothing [closed]

  - by derty

  My private server has 2x1gb Ram working with a 64bit Debian and an Q6600 Intel. This runs 2 virtual mashines on it each one recives 512mb RAM. Which you can immagine is a bit tight for the hole system. Now i got 2x2gb ram from a friend. I'm not sure if thery are clocking at the same speed, but i'm sure my power adaptor is not on his limit and can handle that. So there are 2 ram sockets left at the mainboard. I shuted down the system and build in the 4 gigs and looked what happen. After pressing the start button, everything gets noisy as known BUT the screen shows nothing, not even the bios stuff it usally does. Why isn't the system booting? I can immagine that it does not direkt link between booting debian and the bios not showing a thing. Or is it Grub? I mounted the system disk, and i can see it, switch folders write stuff with "vim" it does not seems like there is a problem.

• How to fix Windows 7 device removal notification loop

  - by Barry Kelly

  Bit of an odd one this. One of our PCs is getting caught in a loop some time after being turned on, usually after a USB storage device has been attached - sometimes an iPod, sometimes a GPS. Specifically, Windows Explorer starts showing a drive icon and letter (E:, as of right now) for the System partition (the small hidden one at the start of the boot drive). Then, the icon disappears. Then it reappears again. And disappears. It does this very quickly, at what looks like maybe 50 times a second. CPU usage in this loop is also very high; averages about 66%. This machine has an i7 920 CPU, which is quad core with hyperthreading; so this usage rate works out to about 5 100% busy threads, along with whatever normal idle load is (particularly Task Manager itself). Inspecting with Process Explorer shows that the device removal notification infrastructure has gone berserk. The threads in system service processes (i.e. apart from Windows Explorer) which are using all the CPU power relate to device notification. The Disk Management MMC snap-in also fails to run when the loop starts. The only way to break the loop, it seems, is to reboot the machine. Anyone seen anything similar to this, and know of a way to fix it? Machine details: Windows 7 x64, fully patched i7 920, 12GB RAM Intel SSD 80GB (X25-M, I believe; not G2) 2TB 5.2K disk for bulk storage AMD HD 5870 Further hardware details await. I'm going to go through and update all drivers I can find.

• Hibernate & Sleep broken after IE 9 RTM installation in Windows 7 x64.

  - by AKa

  I have a question about hibernation. I installed Internet Explorer 9 RTM x64 on my Windows 7 x64 SP1 desktop machine. After this, computer don't entry the hibernation or (hybrid) sleep state properly. After I hibernate the computer the monitor become blank screen and the keyboard and mouse are inactive. But the machine is still running and there isn't any possibility to switch them off as only with power button. But this is recognized on next start as ineligible because of log entry with message “The previous system shutdown at xx:xx:xx on ?xx.?xx.?x was unexpected“ and menu with safe mode option. I’m clearly not sure if it has something to do with Internet Explorer installation, but I’m definitely guaranteed that before of this I never had some problems with hibernation or (hybrid) sleep. In Windows logs isn’t something suspect. I switched the hibernation off and on, installed new drivers for mainboard, graphic and network card, checked the hard disk, nothing was helpful. This is really sad, beacuse I don't like to switch the computer completely off because it takes longer to boot. Any suggestions?

• OpenVZ container is running but does not show in vzlist nor can I find the private/conf files for the container

  - by Kakeakeai

  I was creating a new OpenVZ container on one of our VPS Nodes while the power went out for that machine. After bringing the machine back online I could no longer access the container CTID=101. I could not destroy it using "vzctl destroy 101", I can not enter or control it, and "vzlist -a" does NOT display any containers at all (this was a fresh node and the first container was being created). I decided to create a new container at this point assuming that the old container just was not saved for some reason. However when I go to add the ip/host to the new container I get a warning that the IP is already in use. After doing a ping to the IP I realized there was a machine on that IP. I SSH into the machine and discover it is the OLD container that some how is orphaned. I can not find it on the filesystem, I can not find it using VZ commands, and It is set to start on Node boot so it is impossible to shutdown (even ssh in and typing the "shutdown now" command just reboots the container not shut it down). Is this a flaw in OpenVZ or am I missing something? I have all the outputs and logs if needed. Thank you all so much in advance.

• Run 3 monitors on two different video cards?

  - by hullot

  Can I run 3 monitors on two different video cards? I have an ATI and Nvidia brand card. The ATI has 2 HDMI connections. They both work. Both cards are also picked up in Windows, one being the ATI and the other one as the Nvidia, but it says VGA Controller, although the card only takes 2 DVi. So, one DVI cable goes into that Nvidia card. 3 Monitors, but only 2 the HDMI ones from the ATI pick up, not the third one which is connected to the Nvidia via DVI. How can I run three monitors then? I suppose I can't install both drivers, so I'm unsure what to do. Is this possible? I just want the Nvidia card to power the third screen, no gaming on it, nothing. Also the ATI is picked up as primary card as well, so no hurdle there. EDIT: Hm, just installed the Nvidia drivers and it picked up the third screen no problem. Hope there aren't any major conflicts. Will post this as an answer as correct when I'm able. Can't as a new user.

• zfs pool error, how to determine which drive failed in the past

  - by Kendrick

  I had been copying data from my pool so that I could rebuild it with a different version so that I could go away from solaris 11 and to one that is portable between freebsd/openindia etc. it was copying at 20mb a sec the other day which is about all my desktop drive can handle writing from the network. suddently lastnight it went down to 1.4mb i ran zpool status today and got this. pool: store state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: http://www.sun.com/msg/ZFS-8000-9P scan: none requested config: NAME STATE READ WRITE CKSUM store ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c8t3d0p0 ONLINE 0 0 2 c8t4d0p0 ONLINE 0 0 10 c8t2d0p0 ONLINE 0 0 0 it is currently a 3 x1tb drive array. what tools would best be used to determine what the error was and which drive is failing. per the admin doc The second section of the configuration output displays error statistics. These errors are divided into three categories: READ – I/O errors occurred while issuing a read request. WRITE – I/O errors occurred while issuing a write request. CKSUM – Checksum errors. The device returned corrupted data as the result of a read request. it was saying low counts could be any thing from a power flux to a disk event but gave no suggestions as to what tools to check and determine with.

• What are my options in replacing the noisy fan in my Linksys Cisco SRW2008P managed GigE switch?

  - by Fred Sobotka

  My first managed GigE switch, the Linksys SRW2008, was a dream, until it started randomly chattering on various ports. That started while I was on the road all the time, which made it take forever to diagnose, but that's a different problem. When I finally determined that the switch was bad, it was still covered by warranty by Linksys/Cisco, so I opened an RMA ticket and returned it. Unfortunately, Linksys/Cisco "upgraded" my replacement switch to a SRW2008P, which has Power over Ethernet features I never planned on using. That by itself wasn't so bad, but it's my guess that the inclusion of PoE functions in this model required a tiny, super-loud internal fan to keep everything cool. This wasn't something I wanted or asked for, but, now that I am stuck with it, I am investigating options for replacing that little internal fan with something far quieter. For example, if I attach a larger fan to the outsite of the chassis, I think it could push enough air to replace the stock fan that is currently there. Any advice on carrying this out? I have no interest in melting my switch due to insufficient ventilation.

• Installing a new Motherboard in a HP xw6200 case

  - by thing2k

  I have a HP xw6200 Workstation, that is rather long in the tooth, and with 2 physical CPUs, it is quite inefficient. So, the plan was to upgrade the internals. Nothing special: AMD Athlon II X4 640 ASUS M4A78KT-M LE (mATX) 2x 2GB DDR3 1333MHz RAM. 3p under my £150 budget The issues: The pin connector for the front panel isn't a good fit, but I can trim it to size. The PSU has a 8-Pin Power connector, unsurprisingly, the new board has a 4 pin socket. The pins do line up, but I would have to cut it in half to fit. Finally, due to the weight of heat-sinks, they are screwed directly into the case. It turns out that these screws also lock the motherboard in place. As to remove it, you remove the heat-sinks, slide the motherboard across and lift it out. I tested the new board for fit, and while it slots in fine, it's not secure. There is nowhere to screw the board down, it is just held in place with plastic standoffs. The only idea I had, was to wedging something between the side of the motherboard and part of the case. Any suggestions?

• Remote Desktop leaves host unresponsive

  - by Jeff Dalley

  I have my desktop PC at home set up to accept remote connections, and I often connect to it from work on my laptop via mstsc.exe. However, every time I remote to it, I find when I go home that despite the monitor being on - it's not receiving an image and it looks as though the computer is hibernating/asleep. I basically have to restart it whenever I get home and I know there's an answer for why its doing this. More details: When exiting the remote session, I have tried both logging off the account, and closing the RDP window without logging off; both give the same result. When I get home to the desktop I of course try moving the mouse, ctrl+alt+del to see if its responsive to restart, multiple key-press to see if I can get any audio out of it; It seems pretty obvious its sleeping/hibernating in some way: Nothing happens in any of these cases and a physical restart is necessary. Both desktop and laptop are running Windows 7 Ultimate. I'm thinking it really is sleeping/hibernating it, and I'm not sure why because left alone my desktop's power options are set to never turn off the HDD or change its state - I leave it on 24/7. This could be a stupid error on my part but I just can't see it! Thanks.

• Dual Monitor + Virtual Desktop software (plus for cube)

  - by xenithorb

  I've recently purchased another monitor, my first one being a TV and being much larger. I now sit at a desk and use my shiny new 24" LED more often, but I like to extend the desktop into the TV. The problem presented with this is to save power and the longevity of my 47" VIZIO, I try to keep it off when possible. What I'm seeking sounds very simple - If any of you have ever used Compiz or Deskspace (Yod'm) - You'll know what im referring to when I talk about a "cube." The most important functionality I'm looking for is the ability to scroll desktop contents between both displays and virtual desktops. Deskspace does and excellent job of presenting an attractive cube, but it creates a separate cube and virtual desktop space for the second extended monitor (now the TV) - Again, what I'm looking to do is scroll between virtual desktops, by passing through both monitors. The net effect of this functionality would allow me to scroll the contents of the extended monitor to the first monitor should a window get caught there without having to turn on the TV. So imagine the horizontal portion of a cube as being actual real monitors - is there anything that allows one to rotate desktops between displays?

• Upgrade or replace?

  - by Felix

  My current PC is about four years old, although I have made upgrades to it throughout its existence. The current specs are: (old) Intel Pentium D 2.80Ghz (32K L1 / 2M L2), Gigabyte 945GCMX-S2 motherboard (old) 2.5GB DDR2 (slot0: 512MB @ 533Mhz; slot1: 2GB @ 667Mhz) (new) HIS Radeon HD 4670 - I think this is limited by the motherboard not supporting PCIe 2.0 (?) (old) WD Caviar 160GB - pretty slow (new) WD Caviar Black 640GB (if any more specs are relevant, let me know and I'll add them) Now, on to my question. I've been having performance issues lately, both in video games and in intensive applications. A couple of examples: Android application development (running Eclipse and the Android emulator) is painfully slow (on Linux). I only realized this when, at my new job as an Android dev, both tools are MUCH quicker. (I'm not sure what CPU I have there) The guys at my new job got me NFS Hot Pursuit, in which I barely get like 5-10FPS, even with graphics options turned all the way down My guess is that the bottleneck in my system is my CPU, so I'm thinking of upgrading to a Quad Core i5 + new motherboard + 4GB DDR3 (or more, 'cause I know you'll all jump and say 8GB minimum). Now: Is that a good idea? Is my CPU really a bottleneck, or is the whole system too old and I should replace it? I run Windows 7 on the old, 160GB HDD (which is on IDE, by the way). Could this slow down games as well? Should I get a new drive for Windows if I want to play new games? I know nothing about power supplies. Could that be a problem / will it be a problem if I upgrade to an i5? How come DiRT2 works on full graphics settings (pretty amazing graphics by the way) and NFS Hot Pursuit pulls only 5-10FPS?

• Imported Hyper-V VM hangs

  - by BParker

  I have a pair of Hyper-V servers (Server 2008 R2 + Hyper-V role). I have duplicated one VM (exported from the first Hyper-V server to the Second) which seems to keep hanging. The VM is running XP SP3, and has the Virtual Additions installed. The first version runs fine, cpu normally around 0%-2% when idle and responds happily. The second version runs very poorly, and keeps running at an idle of around 8% cpu. I have checked the VM with Process Explorer, and the Idle process is (as expected) taking nearly all the cpu time, but what it's not using doesn't seem to show up in any other process. For example at one point idle dipped to 73%, but i could only account for anoth 4.5% in other processes. After some time (around 1-2 days) the VM seems to become so unresponsive, the only way to resurect it is to power-off the VM and reboot (shutdown via the Hyper- V console of via the VM seems to be impossible). Does anyone have any suggestions on how to trace the source of the problem? Thanks

• UEFI boot options gone

  - by user1797930

  I ran into some issues booting Windows after trying to make a complete backup of the disc. After searching for information about some of the error codes, I found advise to change some BIOS settings, but instead I thought I would just "restore defaults" to make sure all settings were set as originally intended. After doing so, all UEFI boot options except for "Windows Boot Manager" are gone. That means, including the CD/DVD drive, so I cannot even boot from a recovery DVD anymore - and as explained, Windows is not able to boot either. Do you have any advice? When I added a secondary drive originally, it was automatically added to the boot options menu. Even when removing and re-adding the drive physically, the option does not appear again. I have tried unplugging power, and hold down start button for 10 seconds, and boot afterwards - no change. It's a laptop so removing CMOS battery is not an option. I have read information that it is an issue with data removed from NVRAM, but I am unable to find a way to recover it. "Add new boot options" requires a path - but the CD/DVD was originally available without any CD's in the drive - so there is no path available to add the drive. I did try to open EFI shell, but it seems not to be embedded in the UEFI/BIOS. It just says "not found". I'm really lost here - any advice is appreciated.

• Ubuntu server 10.04 disconnects after short periods of inactivity on my site

  - by user57019

  I'm new to Ubuntu (installed it for the first time just a couple of days ago on my server). I've Ubuntu Server 10.04 and am just using the terminal, no GUI like Gnome. So far it's working pretty great except for one big thing. Whenever I go to sleep and there's no activity on my server (it's not a big site so active users drop to 0 during the night), the server kind of disconnects. The only thing that can bring the site back online is to restart the whole server. I've tried disabling powersaving by using setterm but that changes nothing. Even if I wake up the server by pressing any key or so the site wont go back online! I've tried just restarting both Apache and MySQL (I'm using LAMP-server btw) but not even that works. But as soon as I turn the power off and on at the server, everythings work like normal for a couple of minutes of inactivity (~5-15 minutes I'd guess) and then it's down again unless someone logs in to the site and is active. I was previously using XAMPP on my laptop with Windows XP and that worked 24/7 so I don't think it's anything with my router or ISP. This is driving me crazy! My site is down all the time I'm in school as I have no possibility to restart the server if it becomes offline. Does anyone have a clue to what could be wrong?

• How to fix Windows 7 when System Recovery Options hangs?

  - by seansand

  The battery power ran out on my HP G60 laptop and it shut down. Even after recharging, Windows 7 will now not start up. After any attempted startup, it bluescreens and takes me to the "Startup Repair (recommended)" / "Start Windows Normally" console screen. "Startup Repair (recommended)" appears to be the right choice, but when I choose it, I get taken to a screen which appears to be System Recovery Options (it's the same wallpaper as the screenshots here: http://www.sevenforums.com/tutorials/668-system-recovery-options.html). However, I just get a cursor with nothing else; no "System Recovery Options" window ever pops up. (A black console screen does pop up for a split-second but too fast to be able to read the text.) The empty screen with cursor hangs indefinitely. System Recovery Options normally runs off of a partition on the laptop hard drive. When I got the laptop, I also created a System Repair Disc (in fact I have more than one) and when I try use any of them; they all result in the same wallpaper and empty screen with lone cursor. Ctrl-Alt-Del does nothing. The computer did not come with a Windows 7 installation disc, so there's no obvious way to reinstall Windows 7. Safe mode does not work; startup fails and I just get sent back to the "Startup Repair (recommended)"/"Start Windows Normally" console screen. "Start in last good state" does not work either, same result as above. Running a memory & hard disk check found no errors. Do I have any options at all? "System Recovery Options" seems to be what I want, but the screen that is supposed to take me to them just hangs.

• 3-4 old computers = general purpose cluster?

  - by TheLQ

  I have 3 old computers lying around right now running a P2 at 800 MHz(?), Intel Mobile 1.6 GHz, AMD Athlon XP 2000+ at 1.66 GHz, and (might not use this) P4 at 2.7 GHz, all with 512 MB Ram, and am considering clustering them together for fun/knowledge. They would be running an undecided version of linux, preferably ubuntu based. The issue is what I want to use it for: general computing and occasional video encoding. By general computing I mean day to day tasks. However I'm not sure if every program started by a single X session is going to exist on the same machine, defeating the purpose of such a system. Will programs be split up or exist on one machine? Second, assuming this is running 100baseT ethernet (not sure if the PCI slot itself could handle Gigabit), would the speed of having a program exist over the network be an issue? It seems that the constant asking of various things in RAM would be quite slow. And before you say "buy another computer!", that's not the point of this question. I'm asking would it be usable, not necessarily practical. And yes I know, this is going to be extreamly power consuming.
