Are you using integrated or discrete graphics (video card)? Your video card may have died.

Did it come disconnected from the computer?

Is the computer running normally? Take off side panel and see if the fans are spinning.

It could be stuck in sleep mode, I've had this happen before. Remove the cmos battery from motherboard for 5 minutes and put it back in.
