Are you running an additional Video card? Or are you using the built in one.
You might try cleaning the connector / plugs with acetone from finger polish remover or de=natured alcohol.
Never jam anything on a computer.
If its an add on card, remove it and reboot. Shut down and reinstall card and reboot.
keep me posted please,

Try this if you haven't already, UNPLUG THE MONITOR FROM THE WALL.
LEAVE UNPLUGGED FOR 5mins and PLUG IT BACK IN AT THE WALL.
Alternatively try another dvi cable could be a dodgy cable.

This sounds like a video card driver issue or the card it self. Make sure all cables are plugged in snug. Once done try to boot in to safe mode by restarting the computer and while it is starting keep on tapping key F8 and choose safe mode. If this works it is driver issue. If nothing happens it is the card it self. Might have to take it to a authorized repair shop. Hope this helps.
