Windows XP Pro restarts when idle for 5 minutes
Posted on 2008-11-14
We have a Windows XP Professional SP3 Computer that will consistantly restart every 5 minutes when left idle (no mouse movement). If the user continues to work and move the mouse Windows will continue to run. As soon as the mouse activity stops for 5 minutes (give or take 30 seconds) you can hear hard drive disk activity, the hard drive activity light flashes, and Windows will restart. After logging back in you will get the standard "Windows has recovered from a Serious Error" message and all works fine until you leave XP idle for 5 minutes.
This situation does not occur in SAFE MODE. If in SAFE MODE Windows will not restart when left idle.
In an attempt to fix the situation I have done the following without success in fixing this problem:
Removed Windows XP Service Pack 3
Ran Scandisk (it ran on reboot)
Scanned for Virus's using NOD32 and Norton Corp Edition - zero infections detected.
Scanned for Spyware using Spybot 16 and SDFix - zero infections detected
Turned off power options - screensaver, hybernation, standby, etc. Setup power scheme to "always on"
Turned of Hyperthreading in Bios ( I don't see an option to disable EIST in the bios)
Any advice would be appreciated
