Hey. My PC seems to enjoy eating power supplies. I recently had a problem with it and replaced the power supply. It booted two or three times only to have the problem repeated. When I boot up, nothing is displayed (the screen doesn't even come out of sleep mode). There is a long beep that is repeated, which I believe is a BIOS error beep. All components have power, even the video card which I had suspected was dead because of the display problem. Like I said, this was fixed when I replaced the power supply but has started again. Any ideas? Cheers!
