• Backup data from RAID 1 disk out of its server

  - by Doomsday

  I'm facing with a pretty easy problem in my opinion. I've extracted a working disk from a RAID1 and I'm looking to copy only data (FS and RAID configuration doesn't matter) into another location (another FS). My problem is I'm not able to mount properly this disk into another linux. I've first looked the partition table : # fdisk -l /dev/sdc Disk /dev/sdc: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders, total 1250263728 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 63 1249535699 624767818+ fd Linux raid autodetect /dev/sdc2 1249535700 1250017649 240975 fd Linux raid autodetect /dev/sdc3 1250017650 1250258624 120487+ 82 Linux swap / Solaris I've understood I should use dmraid tools.

Anyone has a clue ?

• How do I get a network printer installed in ubuntu 9.04?

  - by SoaperGEM

  My girlfriend's work computer now has Linux on one of the partitions, and for the most part it's running fine--except that I can't seem to get the network printers configured right. There are two of them: a Lanier MP 7500/LD275 and a Lanier MP C3000/LD430c, and Linux seems to have found them both automatically. I'll go through the steps of what I did, and what exactly went wrong. I went to Administration Printing, and clicked the new printer button. It searched for printers and found them both, listed under "Network Printers." I added them as new printers in succession. However, when I clicked "Print a Test Page," it failed saying there was a broken pipe. The device URIs were saved as socket://[ip address]:9100. I changed these to lpd://[ip address] per some online tutorial, which at first looked like it might have worked (but didn't). Then when I tried to print a test page, it first said Processing (and sometimes even Processing - printing test page, 4%, but always subsequently displays Idle - /usr/lib/cups/backend/lpd failed. Help! What do I do? It seems like Linux can find these printers just fine, and the drivers seem to be in place, so what's going wrong?

• Move EFI System Partition to another drive

  - by Pincopallino

  I had a Windows 8 installation on an HDD, using UEFI as boot. The HDD has the following GPT table: DISKPART> list partition Partizione ### Tipo Dim. Offset --------------- ---------------- ------- ------- Partizione 1 Ripristino 300 Mb 1024 Kb Partizione 2 Sistema 100 Mb 301 Mb Partizione 3 Riservato 128 Mb 401 Mb Partizione 4 Primario 390 Gb 529 Mb Partizione 5 Primario 540 Gb 390 Gb (I apologize it's in Italian, but the translation is quite straightforward). I recently bought an SSD drive, connected it and installed a fresh Windows 8. Now I have a working dual boot, but the UEFI partition is on the HDD instead of the SSD. Here's the SDD partition list: Partizione ### Tipo Dim. Offset --------------- ---------------- ------- ------- Partizione 1 Riservato 128 Mb 1024 Kb Partizione 2 Primario 221 Gb 129 Mb I think that the best solution would be to have it on the SSD for two reasons: the first is performance (I guess it would be a little be faster on the SSD due to the spin up time for an HDD, but I may be wrong about that) second reason is consistency. As I plan to use only the Windows 8 installation that is located on the SSD and I'm probably going to erase the system partition on the HDD to use it as a data storage device, I think that the boot partition should be on the same drive as the OS. So the question is how do I move the EFI System Partition to the SSD?

• I need to preserve a tape using symantec backup exec. I'm aving trouble doing so

  - by MrVimes

  Please forgive me if this is the wrong stack exchange site. Please suggest which one I should post this to if it is. There's an automatic tape machine running in a remote location, with software (symantec backup exec 11d) Recently one of the servers being backed up had problems with its raid controller, so one of the drives has become invisible. I need to preserve the last good backup of that drive so I am trying to replace the tape with the most recent backup of that drive on it with one of the scratch tapes (blank tapes) present in the machine. I've tried the following... Associate the blank media with the media set in question (Wednesday) For the existing media (the tape with the data I want to keep) I click 'move to vault' and move it to the offline vault. I associate it with something other than 'Wednesday' (a media set called 'keep data infinitely...') I then do an inventory on that slot. The above steps I'm led to believe are supposed to put the fresh tape in the slot that had the tape I want to keep in it. But it just keeps showing up as containing the tape I want to keep after the inventory. (after refreshing the device tree) I am a complete newbie with this software. Can you tell me what I'm doing wrong, and/or tell me how to acheive my desired goal Edit: Just want to point out that I did try to get help directly from symantec with this, but having jumped through countless hoops to create an account and create a support ticket my progress was halted by requiring something called a 'tecnical contact id' at the final step with no explanation of what it is or how to get one.

• Soundtest works, but no other sounds and windows starts very slowly

  - by Kristian Kari

  So suddenly all sounds on my computer stopped working expect the sound test works, but when I go to control panel and audio it says there's no audio device. And audio players and audio on website doesn't work either. and Also windows starts very slowly. I'm not sure if this helps but I'll tell what happened before this. I downloaded this program from a little shady website, I hesitated and for a good reason I guess cos the moment I finished downloading it, my antivir detected it as unwanted program and put it on quarantine. I thought everything was fine, but had some problems with program (won't go to details about it cos it's not really related to audio) so rebooted the computer and I was suprised that windows started really really slowly. It took like 5 mins to load the desktop such. After that I noticed the sounds were missing, I immediately deleted the program since I thought it was causing the problem. But it didn't change much. I tried to find the solution with no success and now I'm just scanning again my computer. I'd be thankful if anyone would be able to help me. I might have left a thing or ten things out, so feel free to ask. oh and I'm using windows xp

• My home router randomly disconnects me and I'm unable to reconnect to it

  - by Roy Tang

  It's happened a few times, I'm not sure how to diagnose/debug, so any advise would be appreciated. Symptons: sometimes the router will randomly disconnect; the connection icon on my desktop (wired to the router) gets that yellow "!" symbol that tells me my connection just went down. At this point I'm unable to ping the router. afterwards I try to reset the router by removing then reconnecting the power jack on the router side (this is the fastest way as I can't reset the power strip it's connected to without rebooting my desktop. the router has a reset thingy, but it's one of those things where i have to find a pin to stick into the hole, and when I get disconnected I usually need to get reconnected immediately so I just pull and put back the power jack), but even after that the connection has the same state. after the router reboots, if I try to connect to it using a wifi device like my ipad, the ipad prompts me for the wifi password even though it had already "remembered" all the settings for this router forever after i finally decide to reboot the power strip, and my desktop and the router boot up again, the connection returns to its normal state somewhat and i'm able to connect to it as normal using the desktop and wifi devices. What do I need to check the next time this happens so I can figure out the problem? Is it possibly because we've been using the power jack on the router as an easier way to reboot it? Should I be shopping around for a new router? If it helps, the router is a DLink DIR-300

• Problems with USB-Devices using VDR

  - by emmsinator

  Hey Guys, I'm using VDR on vSphere4. It works sucessfully. I've already backuped several VMs with VDR and I like it very much. But now we got a problem. We have 2 VMs, using an USB-Device Server with a stick plugged in, which is definetely need by these 2 VMs for Licensing and so. Every time, I start the Backup process, the VMs lost the communication to the USB-Server and its stick after building the snapshot and while online. Because of that, the software on these VMs can't work correctly. I have to restart both Machines to solve this problem. These fact is bad for an automatic backup. Does VDR have a special function for those cases or is something like this already known? It would be no problem, to shutdown the servers for building snapshots on Saturday or Sunday. Can VDR initiate a shutdown before starting the backup process? Otherwise I must try to use scripts, but that wouldn't be so nice. Thanks a lot for your help.

• Redirecting or routing all traffic to OpenVPN on a Mac OS X client

  - by sdr56p

  I have configured an OpenVPN (2.2.1) server on an Ubuntu virtual machine in the Amazon elastic compute cloud. The server is up and running. I have installed OpenVPN (2.2.1) on a Mac OS X (10.8.2) client and I am using the openvpn2 binary to connect (in opposition to other clients like Tunnelblick or Viscosity). I can connect with the client and successfully ping or ssh the server through the tunnel. However, I can't redirect all internet traffic through the VPN even if I use the push "redirect-gateway def1 bypass-dhcp" option in the server.conf configurations. When I connect to the server with these configurations, I get a successful connection, but then an infinite series of error messages: "write UDPv4: No route to host (code=65)". Traffic routing seems to be compromised because I am not able to access anything anymore, not even the OpenVPN server (by pinging 10.8.0.1 for instance). This is beyond me. I am finding little help on the web and don't know what to try next. I don't think it is a problem of forwarding the traffic on the server since, first, I have also took care of that and, second, I can't even ping the VPN server locally through the tunnel (or ping anything at all for that matter). Thank you for your help.

• Enable bitlocker an save key to share

  - by user273694

  I have searched all over the web but cannot find a complete answer to this: How to enable Bitlocker on a laptop with TPM, and store a file with the Bitlocker recovery key and TPM password by USING THE manage-bde command line tool. The file should be the same as when created in the Bitlocker manager UI. I DO NOT want to save to AD. The same question was asked here but was not answered correctly. The goal is to write a script to be used with an endpoint manager. I have tried the following: manage-bde -on C: Works fine, but does not create or save a key. manage-bde -on C: -rk C:\myfolder\ and manage-bde -on C: -RecoveryKey C:\myfolder\ -rp The output from the last two methods state that a key has been saved to c:\myfolder and so on, but that is not the case. It also says that I have to: Save the password in a secure location Insert a USB flash drive with an external key file into the computer. Restart and run hardware test type "manage-bde -status" to check if the hardware test succeeded After a restart, I get an error saying that Bitlocker could not be enabled because the bitlocker startup key or recovery kpassword cannot be found on the USB device.... C: was not encrypted. Why am I asked to insert a USB?? I simply want to encrypt the hard drive and save the recovery information to a file automatically. Is that too much to ask? Help please!

• IDE compatability with SATA image

  - by Ormis

  We had an old CNC machine's hard-drive fail recently. The hard-drive is an old 1275MB IDE (Seagate) and there were defiantly bad sectors on it. I was able to image the contents of the drive onto a drive in my computer before it became completely unusable (I used DD, replacing all bad sectors w/ 0s). After running a couple chdsks, the SATA drive will boot off of the image. This is great, but there's one problem. The CNC machine old and requires IDE, I've attempted to copy the currently booting image off of the SATA drive and onto IDE drives numerous times in numerous ways and every time I do so the machines return that a boot device cannot be found. Some other information: The file system is fat32, running windows 98 The SATA drive is an 80gb drive I have tried copying the image to three 20gb and two 80gb IDE drives I have checked the jumper on the back of the IDE drives when using them If anyone has any ideas, questions, suggestions, etc. please let me know. P.S. I would just put a fresh install of win98 on the machine if i had the installation media (so that's out of the question). And if it comes to it, this is my last week working here, so I'll leave that to my co-worker. EDIT: Also, I have tried using Clonezilla as well as straight up DD to copy the image to the IDE drives.

• Partition is missing in /dev

  - by haimg

  I'm having a strange problem since I moved from Centos5 to Centos6. I have three disks, first two are used as a RAID1, and third one is a stand-alone backup disk that is not listed in /etc/fstab (it is mounded when needed and then unmounted). My problem: After a boot, /dev/sdc exists but /dev/sdc1 does not. Also, the links in /dev/disks are also absent for the first partition of sdc. Disk itself is fine, and if I hot-remove it and plug it back in, /dev/sdc1 appears ok and everything is working. My question: What subsystem manages auto-discovery of disks, partitions, etc. during the boot process (e.g. what creates /dev/disks/by-label)? How do I configure it to scan /dev/sdc too and create all relevant files and links in /dev ? Edit: Here's the relevant part of dmesg output (the only place sdc appears). It does list sdc1, but it's not in /dev! sd 1:0:0:0: [sdb] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) sd 3:0:0:0: [sdc] 976773168 512-byte logical blocks: (500 GB/465 GiB) sd 1:0:0:0: [sdb] Write Protect is off sd 1:0:0:0: [sdb] Mode Sense: 00 3a 00 00 sd 1:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 3:0:0:0: [sdc] Write Protect is off sd 3:0:0:0: [sdc] Mode Sense: 00 3a 00 00 sd 3:0:0:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sdb: sdc: sd 0:0:0:0: [sda] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: DMAR:[DMA Read] Request device [00:1e.0] fault addr 361bc000 DMAR:[fault reason 06] PTE Read access is not set sdb1 sdb2 sdb3 sdc1 sda1 sd 1:0:0:0: [sdb] Attached SCSI disk sd 3:0:0:0: [sdc] Attached SCSI disk sda2 sda3 sd 0:0:0:0: [sda] Attached SCSI disk

• Is there a monitoring software suite that will alert me if it has received no activity in a time period?

  - by matt b

  This might be a very basic question, but I am not very familiar with the exact features of Nagios versus Munin versus other monitoring tools. Let's say we have a process that needs to run daily for some very important infrastructure reasons. We've had cases where the process did not run or was otherwise down for a number of days before anyone noticed. I'd like to set up a system that will enable me to easily know when the daily run did not take place for some reason. I can set up this process to send an email on every successful run (or every failed run), but I do not trust that the people receiving this email would notice an absence of an "I'm OK" message. What I am envisioning is some type of "tripwire" service which this V.I.P. (very-important-process) can send a status message to each time it runs, whether successfully or not; and if the "tripwire" service has not received any word from the VIP within a configurable amount of time, it can then send an alert to someone. (The difference between what I envision and the first approach I outlined is a service that sends a message only in abnormal conditions, rather than a service that sends messages each day that the status is normal/OK). Can Nagios be set up to send an alert like this, if it has not heard from a certain service/device/process in N days? Is there another tool out there which does have this feature?

• P2V Wouldn't Boot, Rebuilt initrd, Need to Clean Up

  - by Mike Soule

  We have a CentOS 5.4 server (build 2.6.18-164.el5xen). We went to P2V this server so we can have redundancy, the physical only has one PSU. The P2V only completed 99% of the way, we have a VMWare ticket opened, but they marked the ticket as low priority. I was able to boot into a rescue disc of Red Hat 5.4 and rebuild the initrd with the help of this blog post. Now the only issue is the original server had a modified initrd, which was also from a different OS build and made by an outside provider. We do not have a document outlining modifications. My question is, is it at all possible to copy the initrd off of the physical server and replace it on the virtual and some how have the virtual machine boot? Thanks for any input. Edit: I copied the initrd img from the physical and it recreated the original issue. Here is a screen capture of the error. http://i.imgur.com/MqC73.jpg Edit2: echo Scanning logical volumes lvm vgscan --ignorelockingfailure echo Activating logical volumes lvm vgchange -ay --ignorelockingfailure VolGroup00 resume /dev/VolGroup00/LogVol01 echo Creating root device. mkrootdev -t ext3 -o defaults,ro /dev/VolGroup00/LogVol00 echo Mounting root filesystem. mount /sysroot

• file system that allow to specify different RAID level per directory and change it afterward

  - by Adam Ryczkowski

  I have 5 hard drives, where I want to keep my data. Some of my files are more important, and some of them are less. So some of them I wish to put on RAID-6, and for some it RAID-5 is sufficient. It is difficult to predict at the moment of creation of the arrays how much space of each type to declare. What I would do if I didn't hear about zfs, is partition the hard drives into identical 100GB partitions, and as my needs grow, assemble those partitions into md devices using linux-raid. Then, I'd combine those devices using lvm into logical volumes where I'd put my data. So when I'd need more space of e.g. RAID-6, I'd take 100GB partition from each hard drive and assemble them into another RAID-6 md device and would use it as physical storage for the logical volume group dedicated for RAID-6 data. Then I could grow the file system on this logical volume. On top of RAID-6 and RAID-5 Volume Groups (managed by lvm) would reside completely independent file systems, which I'd later merge with multiple mount --bind into a single directory structure that would reflect the logical structure of data rather that of the storage. But now, when I heard about the ZFS with all the performance, data-healing and compression capabilities I cannot stop thinking if it can help me. If so, what do you think would be the best setup?

• what type of laptop do I need to run a amd64 or i386 VM?

  - by Frank Schwieterman

  I was running an amd64 build of Ubuntu on a VM on a Windows host which was also amd64. Later I found I could not run the same amd64 iso on my laptop, which is intel without hyper-V. I was confused I thought chipset mattered, but maybe it does not. When buying a PC or Apple, is there anything to check about the chipset to make sure it can run different types of VMs? In my case, I was trying to run ubuntu on a Thinkpad T520. Per answer below, I did need to enable some bios settings. I'm still having some issues. Running ubuntu on virtual box, when I try to use ubuntu-12.10-server-amd64.iso for the CD/DVD device to start a new VM, virtualbox complains "Failed to open the CD/DVD image . Could not get the storage format of the medium (VERR_NOT_SUPPORTED). When I try to use ubuntu-12.10-server-i386.iso the ISO is accepted, but then the VM complains "FATAL: No bootable medium found! System halted." I had been using an amd64 iso on my home PC which is amd64 and it works fine, which is why I suspected CPU mismatch was the problem at first. But it seems like I'm having issues, and maybe this superuser thread can be used to verify the cpu is irrelevant in this case.

• Size of modules within initrd

  - by LiKao

  I am currently trying to manually replace the kernel within ubuntu-core on an embedded device with a custom kernel. However when I try to update the initrd my initrd becomes much bigger. Here is what I did: Extract the initrd that was shipped with ubuntu Make a list of all modules within the old initrd get the same modules from the new module director at /lib/modules/new_kernel_version add these modules to the initrd and remove the old ones If I do this my initrd becomes quite bigger than the original one, so I checked the individual modules. I picked the btrfs.ko filesystem driver as an example. So by comparing these two modules I noticed the one I just picked into the initrd was much bigger, which caused the difference in size. -rw-r--r-- 1 root root 999K Nov 14 15:06 btrfs.ko For the btrfs.ko within the shipped initrd. -rw-r--r-- 1 root root 7.2M Nov 14 15:08 btrfs.ko For the new btrfs.ko. What is different between these two modules? Could this be caused by some faulty setting for the new kernel? When producing the kernel I copied /proc/config.gz and used make oldconfig to update it, so all optimisations should be the same for both kernels. Or is there something else which is being done to the modules before they are put into the initrd? Maybe is there even some better way to build a new initrd for the new kernel in ubuntu altogether. Update: I just also tested with an initrd which I created from scratch using the mkinitrfs command within ubuntu, and it has the same size difference that I found for the initrd I manually updated.

• Screen randomly goes blue/black/white

  - by FubsyGamer

  Problem Randomly, while using my computer, the monitor goes dark grey/almost black, or it goes white with faint grey vertical lines, or it goes blue with black vertical lines. It's as if the computer powers off. People tell me I sign out of Skype, Spotify stops playing when it happens, etc. When I look at the tower, it doesn't seem like it's off at all. Nothing changes, fans are spinning, lights are on, etc. If you were only looking at the tower, you'd never know there was a problem The only way I can get it to come back up is to push and hold the power button and turn it off, then back on This never happens while I'm playing video games. I've done 5-6 hour sessions of League of Legends, and it doesn't do anything When I'm just browsing the web, reading email, checking Reddit, etc, it happens all the time. It can happen multiple times in a session, it usually takes only about 5 minutes from the time I start browsing to when the computer crashes This started happening after I moved to a new apartment (this has to be relevant somehow, it was not happening where I lived before) There is nothing in the crash logs or event logs System Specs i5 2500k CPU AMD Radeon 6800 GPU Gigabyte z68a-d3h-b3 motherboard WD VelociRaptor 1 TB HDD Screenshots Device manager About screen Things I have tried I was getting a WMI Error in my event logs, but I fixed it using Microsoft's fix, KB 2545227 I was using Windows 8. I wiped the HDD and downgraded to Windows 7 64 bit I took out the video card and used a can of air to totally clean out the video card, all fans, and the inside of the computer in general. I made sure all of the video card pins were fine, then reconnected it I tried to update my motherboard BIOS, but anything I downloaded from Gigabyte was only for 32 bit machines, not 64. I don't even know how to tell what my motherboard BIOS is at right now I am using a power strip, and anything else connected to it works just fine If I re-seat the monitor cable while this is happening, nothing changes Please, help me. I've been battling this for several weeks now, and it's so frustrating it makes me not even want to use the computer.

• How do you recreate the System Recovery environment in Windows 7?

  - by Howiecamp

  I'm running Windows 7 Home Premium RTM (64-bit) and I want to take advantage of the system recovery tools (eg the Command Prompt) without using the Windows 7 DVD. My understanding is that this environment (WinRE) should be installed to your HDD by default as part of the Windows 7 installation. However, when I hit F8 on boot and select "Repair", I get: Windows failed to start. A recent hardware or software change might be the cause. To fix the problem... Status: 0xc000000e Info: The boot selection failed because a required device is inaccessible. The "Info" line seems like the smoking gun. My next step was to boot from the Windows 7 DVD, and choose "Repair". It indicated my Recovery Environment wasn't on the Windows 7 boot menu (perfect) and offered to fix it. I said yes and rebooted, however same issue as above. In addition, when I booted in to Windows 7 and I looked at the boot menu options, the recovery/repair option was not there. Only my Windows installation. Finally, I ran the Disk Management tool (diskmgmt.msc) and took a look at the contents of my "System Reserved" partition (which was set to "Active" as normal). It's unclear to me what the contents should look like, however it is my understanding that the WinRE environment gets installed to this partition. (As part of the above troubleshooting I followed http://superuser.com/questions/25728/how-to-fix-windows-7-boot-process which lead to http://www.sevenforums.com/tutorials/668-system-recovery-options.html).

• Fixing a corrupted Windows Server 2003 server

  - by Keith

  I have a Windows Server 2003 server that is being mainly used for some reporting done in SQL Server. Recently Windows has started complaining about being corrupted, we are getting an NTFS error 55: The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolume1. The server is RAID 5 and I did have a disk die however the RAID never went degraded since I have a hotspare. I replaced the hot spare and I'm still having problems. When I run chkdsk I get tons of messages.. some are: Deleting corrupted attribute record (128, "") from file record segment 194746 Those go on for a while. Then it deletes some orphan files. Then it does Correcting error in index $I30 for file 132426 And that goes on for a while. Then I get tons of Recovering orphaned file RE1AB6~1.LOG into directory file 534959 I have seen a lot of errors relating to the SQL Server reporting services. What are my options at this point? I would prefer to fix the issue instead of building a new server but I don't know if I can at this point.

• Getting old bluetooth headset out of standby on Windows 7

  - by luagh45

  I think this is the problem, and if not, I'm open to suggestions. I have an old Jabra BT200 that I used to use on my phone. When a phone call was coming in it would beep using its own noises (meaning the phone never rang inside the headset) and then I could push the 'answer/hang up' button and sound and mic would start working. I have now paired it with Windows 7, and it looks good. Under the playback menu I have 'Bluetooth Hands free Audio / Jabra BT200 (Mono Audio) / Ready', and under the recording menu I have 'Bluetooth Audio Input Device / Jabra BT200 (Mono Audio) / Ready'. However when I try to test the speakers Windows sends a sound, but I never hear it, and when I talk in the mic, Windows never hears me. If I right click either the Bluetooth mic or speakers there's an option to 'Connect', but it's grayed out and I cannot click it. As the final piece of knowledge I have, my headset blinks once every 3 seconds when it's in standby and I can't get that to change. If everything was working it should blink once every second at which point I think all of my problems would be fixed. Hence my issue: I can't seem to get my headset out of standby. On my headset I've tried sending it test noises and then pressing the 'Answer' button, but still nothing. The headset beeps when I press it, so it works, it just doesn't ever come out of standby. Is there maybe some way to trick my headset into thinking it's getting a phone call from my computer?

• Windows 7 breaks even in safe mode

  - by delenda

  Hi, I have a Dell XPS M1730 with Windows 7 installed. I noticed last night that after a few hours of use, the fans kicked into full and I couldn't do anything without it taking forever. Minimising windows, opening device manager or even opening process explorer took minutes and a game install I had just started took nearly 4 hours to complete. When procexp finally loaded, the refresh was so slow that it was mostly useless. From what I could gather, it was reporting 60% idle processes with procexp using nearly 40%. There were no hardware interrupts listed. When I rebooted, the problem went away for about 10 minutes and then the same thing happened. The issue persists in safe mode and even after I removed the graphics drivers, which have been an issue in the past, it still happens. Icons flash quite quickly on the desktop periodically and screen refresh is painfully slow. When booting now, the fans kick in to full as soon as the windows logon box comes up and it's taking 10 minutes to bring the desktop up. Chkdsk reports nothing and the raid check says that everything is fine. I'm thinking hardware failure, probably HDD but wanted some other opinions. I'm planning to try a linux live cd to see if it works without using the hard disks. If anyone has any input, it would be greatly appreciated. Delenda
