ok weird one so this is new. artifacts in video playback, and only since updating V30/40/50 SI VGA Driver from ECS.

ive already rebooted three times... they dont show up on the BIOS screen as far as i can tell, only once Windows loads... is that a meaningful clue? im happy to run tests, i just need to know which ones make sense. i have not overclocked anything on purpsoe, but i did install a tuning tool a while back... i want to rule out the cheap explanations before i start pricing repalcement cards. what am i doing wrong??
