I have been using this card for over 2 weeks and all of a sudden I start getting wierd polygons all over the place in games like WoW, and then 3dmark and atitool show these wierd symbols all over the place. I have a psu with 34 amps and 500watts and just one hard drive and a dvd player. I have a asus p5nd2-sli mobo with 2 gigs of ocz 533 ddr2 ram, and have been running my 2.6 d805 at 3.2. Any insight into what this is and what I can do about it? I have tried installing different drivers and flashing the bios and nothing helps.
