This problem started when i first got the pc but was fixed with the use of older drivers. I had a AIW 9600. The problem resurfaced when i tried updating to the latest drivers, and now also that i have upgraded to a 6800gs. They show up in Mark3D 03 test (realy bad) but only on the cpu test not on the video test. They also show up in EQ (realy bad off everything) and BF2 (minorly off weapons). I have tried various video drivers and video settings. I have updated my BIOS and any and all drivers for other components. I've run a system test that checked everything but the mo bo so it might be that but i'd prefer to find a solution that doesn't require new parts.
