    Unexepected Windows XP PC reboot

    Locked

    While troubleshooting several Windows XP computers, I notice that some of them reboot unexpectedly after a certain amount of time for no good reason. Any ideas on why this is happening and how to resolve it?

      What are these systems doing when they reboot?

      What is set in Power Options? I’ve seen where if the hard disk shuts off, the system reboots rather than go into hibernation.

      Here’s a Web site discussing why Windows XP might unexpectedly reboot:

      Perhaps your solution is discussed.

      This can happen with:

      1). Virus/Worm. Sasser is one example that comes to mind. Sometimes if the network isn’t connected the reboot won’t happen in such a case
      2). Problem with overheating. Check seating of CPU Heatsink (clean CPU surface Heatsink Surface, apply small amount of thermal compound), funktioning of FAN (clean away all dust, maybe replace fan if it sits fast), the same applies to the Grafic card.
      3). Powersupply bad or not powerfull enough. Replace it with a higher rated PSU than what is inside.
      4). Bad RAM. If more than 1 units are installed, try with only one, then the other.

      Harddisk is unlikely, as a bad disk would rather cause the system to lockup, and not to reboot. A bad power connection to the disk could cause a reboot though, so try using another connector from the PSU.

      If you are having the same problem with many machines than the cause seams to be software related. Scan the sistem with an AV and try also some spyware detection software like:
      spybot search and destroy , and lavasoft adaware.
      I hope this helps.
      Good luck.

      To get to the reason for the reboot turn off the auto-reboot on system crash (this is turned on by default). Go to:

      Start > Control Panel > Performance and Maintenance > System

      Select the Advanced tab and then click Settings in the Startup and Recovery section
      In System Failure section, clear the checkbox next to Automatically Restart
      Click OK and OK to exit

      Now instead of crashing you will get the bsod with information regarding why the system crashed. go from there.

      Cheers.

      check to capacitors exit to the CPU
      if they are flat on top they are good
      if not they are bad.
      if they bad you will have to replace the motherboard
