OK, im running windows XP, and up till about a week ago, my video picture has been perfect, but now, when i watch videos, the colours in the videos invert. blue becomes red and so on. has anyou come accross this before. Im just waiting on a new motherboard (ASUS P5N32 Premium....join the queue) to make up a new PC to replace this one, but its damn well annoying. Ive got an AGP nVidea 6600 GT...i think (just goes to show how intrested i am) and ie tried fidling with my nvidea setting but i cant find a problem. picures and videos on disk seem to play alright...only thing ive changed recently is the uninstalling of windoes vista transformation pack V5.5, but that was after the colour changes.......any ideas?
