Restart

Hi, for some reason i have a user his computer restarts automatically once in a while using his application or not doing at all just moving his mouse curser around. It doesn't BLUE SCREEN but it just restarts itself. Today what i have done is uncheck under STARTUP and RECOVERY- System Failure- Automatically restart. Any other ideas to trouble shoot this problem? I didn't see any errors in the Event Log at ALL. This is a HP XW6400 Workstation- Intel CPU, 5140 @ 2.33GHz, 2 GIGs of RAM. Windows XP. I switched the users power cord and switch him from the power supply he was on as well. Any ideas????

Does it go through a normal windows shutdown or does it just switch off?  It could be that your processor is overheating.

I think he said it just it switchs off. Where he doesn't even get any options to save anything it just shutoffs and brings up the startup HP Screen. NO signs of exiting just cold shutdown/restart. No errors in logs..

I would suspect it is some form of protection feature causing the shut down.  Seeing as you have turned off automatic restarts in windows it would seem to be bios that is initializing the restart.  Try going into bios and checking the temperature on your processor, most bios' nowdays will have a feature to restart or shut down the computer if the CPU exceeds a certain temperature.

I took a look at the BIOS: under Chipset Bios: It has an option for MCH Error Handling.
Currently this is what it is set to: SET TO : SMI(REBOOT)

Other Options i can choose from are:
1.)NMI(CRASH)
2.)Machine-Check(CRASH)
3.)IGNORE
Called HP they have no clue what IGNORE did. I'm assuming Ignore error? but that may result into something else......

Probably not a good idea to ignore, the problem it is responding to could potentially be causing harm to the computer.  Better if you can figure out what the problem is.  A few things that could be causing the problem are:

Failing memory - run memory checking application or try swapping out memory
CPU Overheating - check that fan is operational, check that heat sink is not fouled with dust, check that heat sink is making good contact with CPU
BIOS Settings incorrect - short the BIOS reset jumper on the motherboard
Unstable voltages - try changing PSU and using a UPS if you have one
BIOS Firmware problem - flash the bios with latest version from manufacturer

Also do all your testing with the minimum of components installed, unplug all modems, sound cards etc as they can cause issues as well.

There are probably a few other things as well that I have forgotton.
