All games play fine for 15-30 minutes sometimes up to 2 hours, and then it will either crash (giving no error,) screen will go blue, or it will restart the computer. I've tried 3 graphics cards (2 nvidia, 1 ati [all installed properly ;-).]) I still get the errors. Personally I've narrowed it down to RAM or Power Supply, but I'm not sure which if either give these problems. Much appreciated in advance,
