Need some help here.

My son plays COD - MW2 and tends to leave it on all day when he goes to school, he at least turns the monitor off, big energy savings there ;\) . He came home yesterday and said the computer was doing something strange, the monitor was displaying the "no signal" screen, So we shut it down unplugged everything, reconnected and still no signal. I have tried all the video outputs (the board is a Gigabyte GA-73PVM-S2H and I had been running with the onboard video), VGA, DVI and HDMI to no avail. I noticed this morning the keyboard appears to be not functioning as well (not able to toggle Num lock). I fear he has baked this motherboard. Any thoughts?
