My computer was working just fine today, but it just crashed out of nowhere and when I started it back up the monitor said there was no signal. I've unplugged everything and held the power for 30 seconds but nothing, I disconnected the monitor and reconnected it and still nothing. I even replaced the cables. The fans are running and there are still lights. I noticed that the restart button no longer works and the DVD player sounds like it's trying to spin, I also noticed that the caps locks light doesn't light up as well, please I really need this computer
Does the oncreen menu for the monitor work? Press the MENU key on the monitor and see if a menu comes up. If so, then it is the PC, or video card. Does the PC have an external video card?
