A bit of speculation here. Perhaps the slot the video card is in is just 
slightly low on providing power to the video card. Ordinary use of the 
card works. Heavy duty use (like gaming) makes the card draw more power 
than the slot can actually provide, producing a crash?

I guess, to check this, try a different slot for the video card (if you 
can).
