I just ordered this 3800+ x2 and now my computer keeps shutting off. No error messages or anything. I went back to xp and I didnt install anything special...there are no error logs too which make me think it's a hardware problem. It is either CPU, PSU, or motherboard. I am leaning towards CPU because I just got it and this started happening, but I don't know...any advice? edit: It powers down, I should say. It isn't restarting or anything. I am immediately able to power the PC back on afterwards. The frequency of this happening is rising as well..
