Last night about midnight I am tired and I get off my computer to go to bed. I turn the monitor off instead of waiting for the screen saver, and pretty much fall asleep a certain amount of time later. I wake up this morning at 7:30 and the computer is off. I hit the power button... nothing. I try again, nothing. I go back to the switch on the back of the power supply, and flip it off, flip it back on. I hear the fan almost start a little bit, so I hit the front power button again, and nothing. I go back to the power supply turn the switch off for a couple of minutes, turn it back on, then the computer started when I hit the front power button again. To my knowledge, out power didn't go out or anything (my alarm clock was still on time and went off, and that is the first thing to go if anything happens with the power, the computer will just restart). So I am clueless as to what happend, I'm figuring it had to be something with the PC. Any ideas?
