need some help guys. I was running an x800 on this board for past few months all was good. Fsb 445+9 4 gig stable chilled liquid cooling. I swapped the chip for a qx6700 quad yesterday. 333+12 4 gig stable once again so all looked good. But when i try and play a video file , dots appear on screen. Does not matter what type of file. DVD, xvid or divx. If i clock down to 3.8 dots are gone. 3D gaming is fine no dots at all and comp is 100% stable. Pci was set to default so i set to 101mhz no change. tried to go up to 105mhz and dots got worse so that might have something to do with it. Did a format but no change. Hope someone can help...thanx
