Yesterday I turned on my computer and ran it for about 15 min, the room it was in was very hot and muggy. I was then organizing the cords behind the computer so I unplugged the monitor from the wall to switch outlets. This shouldn't have done anything to the computer but when I hit enter to turn the monitor back on I got a no signal found message. Ctrl Alt Del didn't work, and the reset button didn't work so I had to hold the power button in to turn the power off. I couldn't get it to work at all after that. No bios beeps and the Diagnostic LED's stoped at the first sequence which is "Power On." Can someone please help me, is it heat related, could I have ruined something. or what?
