I built this PC a year and a half ago. About a month ago my CPU fan died and the CPU ran hot for maybe 3 days (before I noticed anything). I replaced the fan with an Article Cool 7 and the CPU (Q6600) as still at 55C. About a week after replacing the face, I noticed serious graphics problems (8800GTX) in games, with freezing, pixelation, etc.... A week after that, I left my PC on overnight, and the next morning I went to use it but noticed it had turned off. Thinking my wife turned it off, I powered on. It powered on (no boot) and sounded really odd so I did a hard shut off. I turned it on again and boom, nothing. So I realized it was the PSU. I replaced that and the mobo will spin all fans, mobo (MSI P6N SLI) led light turns on, but the PC will not boot, blank screen. I did all the normal stuff, reset bios, reseat everything, tried to boot without ram (no beeps). The only beep I got (more like a squeal) was when I powered on without plugging in the 4pin connectors to the Video Card. I know the monitor works because I am using now as I type this with my laptop plugged in.
So my question to you all, did the PSU dying fry my Mobo or my CPU or both?
