After a clean reinstall of xp home my pc has started shuting down mid game or on sites like myspac or facebook, but it stays on if im just browsing the net. I have had a few blue screen errors and have followed the instructions as best my ability to no avail. Most often than not ther is no blu screen error, it just reboots. I have checked the evnt logs and found several entries from event 1000-1004. all my drivers are updated and my windows updates are current. my pc specs are in my profile and im currently using norton 360. Im going nuts can any 1 help. I hope ive posted this in the correct place.
