I have a Asus mother board A8N32-SLI Deluxe and two xfx graphic cards, 4600 x2 AMD .Raptor 10,000 74gb harddrive, sony cd, xfi sound card xtrem music, antec 550v power, corsair 2gb 3500LLpro .well its not over heating because I have a computer that does the same thing and almost has the same stuff does it also. It turns off that it... it turns off and you can turn it on again push the button and its ok, but does it almost everyday When I play battlefield2. It did it once before not playing the game but other than that only when playing the game after a hour or two or three but I put a bigfan to the side of it and it does not overheat. Dont know what it can be but both computers do it please help all drivers are up to date im not just a user but I built both computers and deal with them daily but I'm out of Ideas please help.
