XP Performance? Unrequested restarts?

[Guest]

I have a P4 1.6G 256mhz. I recently formatted and upgraded from 98SE to XP Pro. I have also bought and installed a new video card and CDRW. Although it was running very slowly at first, I removed all the normal startup processes (MS Office etc) through running MSConfig and it seemed much better speed wise. Also downloaded all the critical updates from Microsoft and the most recent drivers for the video card. When playing games, the computer seems to just restart on its own every 30 minutes or so. I have also turned off the default restart when error occurs but no error messeges comes up.... It just restarts itself... Am a little at lost as to how to explain it (thought that it might have been the video card drivers). Plenty of memory and space. Don't think that I have any worms as the computer was formatted and critical updates downloaded and installed straightaway. The computer has also been scanned with an updated norton Antivirus. Other normal standard processes such as defrag and scan disk has been done. Would appreciate any thoughts or solutions.

Hi,

Suggestions:

Disable Hibernation and Right click My Computer
Icon/Properties/Hardware/Device Manager. Expand USB Controllers/Double Click
USB Root Hub/Properties. Select Power Management and uncheck: Allow the
computer to turn off the device to save power.

To view the event log: Administrative Tools/Event Viewer or
Start/Run/eventvwr.

To review Shutdown Event Tracker data, Open Event Viewer. Click System Log,
scroll to the Event column, and find entries with the number 1075.
