Ace, i have a similar prob sometimes with my Radeon 9000 Atlantis pro, looks like large flickering triangles, at random points in game, happens at, have to close game, defrag usually sorts it, Norton Sys/works, useing latest drivers for card tho.....? happened last night, first time for about a week?

Sounds like what happens if you overclock too far, Have either of you overclocked your cards?

Yea.. sounds like artifacts due to overclocking.
