There was a worm virus out a while ago that caused the computer to restart a few minutes after it was booted up. You may ahve that. update your virus scanner scan and download a patchf rom http://download.microsoft.com
The software may just clash. If thats the case, geta new DVD writer or watsit you got?
That should help if not go to your local nerd. it worked for me.
