Probably a bad graphics card, seeing as it has been used. I recommend checking to see if all the power cables are plugged in correctly, and that the card is seated well in the PCI-E slot. You could also try booting into windows by safe mode (if at all possible) and try to install the most up to date drivers from ATI.
