I don't know what happened; last night the computer was working fine, this morning I try to turn it on and nothing happens? It's a custom Cyberpower computer, if that helps. The only signal of life is that I hear a little electrical short sound when powering it up, and if I unplug the cable for long enough, I can hear the power leaving the computer. What can I do to fix this? It was plugged into a surge protector, so it wasn't a random power outage either.
