On my windows XP computer, I'll just be on the net or something ordinary and randomly the computer will restart. Screen blacks out, computer lights stay on, monitor button blinks orange then hits green and its starting up again. It happens randomly, so I can't really give time increments..Would like to fix this problem. Also I need to uninstall the Nvidia Nforce Network Access Manager if anyone knows how to do this would be helpful as well. Thank you =D
Bumping isn't allowed here... This might be caused by a "system failure". Try going Control Panel > System > Advanced > Startup and Recovery (Settings), then under System Failure uncheck then box that says Automatically Restart. This doesn't solve the problem, but might let you know if it's this kind of problem, then we can troubleshoot further. Let us know if it works.
