Hey I think there is something wrong with my card. I can't watch videos but video games work just fine, this started yesterday. Whenever I try to watch a movie i just get a blank screen, but sound works and it plays for about a minute, after that my computer lags a lot. I've tried all kinds of players, i've used Windows Media Player, VLC, Core Media Player, and i get the same result. This is getting really frustrating someone please help! Did i destroy my card? I have an ATI Radeon X700
