Let's start with the basics:

Is the monitor plugged into the power outlet?
Is the monitor turned on?
Is the VGA/DVI cable plugged into the monitor and the correct video output on the PC?

Unplug the PC. Try these things:
- Make sure you didn't unplug the power connector(s) to your video card if it uses the extra 6 or 8-pin connectors. (I've done this one.)
- Pop out and re-seat all the cards and RAM modules.
- Try resetting CMOS.
