Data is not sent to the monitor
The first thing to do is to pay attention for "beep" when your press the power button (or the reset button) to turn the computer on or reboot it. The beeps that a PC makes tells you a lot about the state of your computer. I couldn't quote for you the exact beeps to listen for, but your manual for your motherboard may tell you. Different beep pattersn tell you what is wrong with a computer.
I think for many common motherboards it is something like 4 beeps to tell you the graphics card has failed. Don't quote me, but that is at least along the lines of how it works if not the exact number.
If you're getting no display after starting your computer make sure you hear one beep. Then, listen for other activity. If you're computer has a floppy drive, listen for the 'floppy seek'. Otherwise, listen for hard drive activity. If it sounds as though there's activity along those lines but still no signal/display on the monitor perhaps check the cable between your PC and the monitor. Never hurts to just make sure the monitor is turned on of course.
If your monitor is on, and the cables are connected securely I wold restart the computer again and check for the beeps. I would be certain to count them and check the manual. Your graphics card may have failed if you hear abnormal beeps (more than one as one is usually the healthy indicator). If you hear no beeps then the PC is not even getting in as far as testing it's devices and could quite possibly be a motherboard failure.
