I wasnt sure exactly where to post this because it could be hardware or software and i didnt see any "Computer Problems" forums.
So anyway, when playing any game on my computer, from little games on miniclips to big games like Battlefield 1942, after around 10 or 15 minutes of game play my computer either completely freezes up or restarts on its own. If the computer restarts then it will usually load to the point just after the "Windows XP Professional" and the blue bar, and the restart itself again....it does this 2-3 times before it starts normally.
I have swept my computer with AVG, Adaware, Spysweeper and Spybot several times, each time picking up nothing.
I have no idea what so ever what is going on here, so if anybody could offer any form of advice it would be great.
