Like i said in me other post i did try an ATI agp card in there aswell, so would both cards being causing the same prob, i dont think it would man. wouldnt trying 2 completely different cards of dif makes prove this. Also my 9800pro is over 6years old and still working ok. I did install Call of Duty 4 and the game itself is running better then ever, so if my card can handle running a new demanding FPS game surely it can move a window without trails. :freak:
you think it could be a bad install of windows XP?
never anything concrete in electronics
clean your contacts...get a swab...
you may have some minor tarnishing or corrosion going on in there
and anything is possibe...could be a bad install...but I'm more inclined to think not
if you have free time, why not do a fresh install
