Graphics card (driver) problems. I just got a new graphics card on the work computer, but it seems the driver is messing up when playing videos. For example I try to whatch something in windows media player and the collors are all greenish/pink sort of flickering. I'm fairly sure it's driver related since it happened after installing the new card, and we tried uninstalling the drivers and everything worked well then (except for the really bad resolution). There was also problems with the sound when whatching things from for example youtube. We didn't get any sound at all, but I figured that out. So anyone else had similar problems and found a solution? I've tried updating the driver, but no luck there.
