I have an Abit NF7-S Ver. 2 MB. Been away for a couple months. Came home and tried to fire up my computer and it wasn't doing well. Sometimes just a black screen. Other times windows would freeze when loading. So..I opened up the computer (and please don't ask me why I did this, because I don't know), and I plugged in the ATX 12V1 plug. The ATX Power 1 was still plugged in as well. I then proceeded to turn on the computer. I heard a tiny pop and smelled what seemed like burnt wires. The computer just shut down. From that point, I could only turn the computer on for just 1 second. In order to do that, I must first shut down the power supply. Turn it back on, then try to turn on the computer (again, it only lasts a second). If I don't shut the PSU down and back on, computer is completely dead. I switched out the MB and the power supply with the same result. Have a feeling I fried my CPU. Or maybe the ON/OFF switch? Any thoughts?
