Computer problem

[saintssuperstar]

I now have a problem with another pc in the house not my weekend lol. Its with my brothers pc. He was on it last night and turned and his foot just tapped the side of the pc and the screen went black. Changed the graphics card to test it out and it worked fine. After shutting it down and then turning it back on the start screen took ages to display the amount of ram and hdd's etc. It then went to the windows did not load properly screen and then after that the monitor went black with the 'no rgb signal input' message. I know both graphics card are not broken so what do you think guys?

specs
amd atahalon socket 939 processor
geforce 7600
1 gig ram
