Computer was working normally and the screen randomly went black and the monitor displayed "no signal".
All fans and lights come on as normal with no error beeps.
I checked all cables and restarted the computer and still nothing.
I've tried with and without the video card, a different monitor, each RAM stick, removing CMOS battery, a separate power supply, and have made sure all internal components and cables have been reseated and are in securely. I've also tried the "unplug computer and hold the power button for a minute" thing.
