Fixing the video card may also fix this however it is more likely that 
you now have 2 problems. You may actually have yet another. A bad power 
supply which is supplying voltages out of spec high and killing the 
cards. Or more likely,  too low a voltage and the card never starts. 
Before you go out and buy stuff, try removing a capture card or two and 
see if  your video comes back. That would point to a bad power supply.

I had a bad supply that was causing all kinds of strange problems and 
since installing a nice new 450 watt supply, I have had no more problems.

Cheers,
William
