Could be several thing

1) Monitor is dead/fried
2) Video Card is dead/fried
3) Drivers went corrupt
4) Something else

Can you even see the boot screen and does the computer POST at all? If you have a spare computer / monitor, try swapping out the computer / monitor to see if either the video card or monitor is dead. That way you can isolate the problem.

^+1, and check your video cable to verify that it is properly connected to the graphics connector on the computer - firmly seated with no bent pins.

Is the computer newly built? If so check your motherboard manual to see where the RAM is supposed to be installed - a lot of mobos require the RAM to be seated in the 2nd slot not 1st
