you get that screen right when its turned on and going through the bios schpeel??? The card is toast, over heating, or needs to be reseated. Usually if it needs reseating you will get no video, but sometimes this will happen, though not very often.
i concur killian . it can't be a driver issue. if the card doesn't work after reseating it the only other possible way to fix it would be flashing the cards bios.
