Graphics card problem.

I've just recently started multiboxing and everything seemed to be going fine until I ran mara. When I jumped off the waterfall my computer froze up for about 30 seconds which is the first time I ever had a problem with my computer. After the lag spike on all of my clients the screens were random colors with random polygons all over so I restarted and when ever I play now distant textures move over each other and is rather irritating. Is there a way to fix this or will I have to buy a new card?

I run a Geforce GTX 260 216 core 896mb graphics card.

Yeah happened to an old card of mine. Interstingly enough it happened in Mara as well. I had to replace mine when that happened.

are you overclocked or is the card overheating? you may have to turn the fan up more using ntune or evga precision and see if that works. otherwise it could be bad drivers or a dieing card :(

I have a life time warranty on my card so it's all good!

i just went to a bfg gtx280 oc, and now for some reason, if there is a lot going on on all 5 wow 2 monitors, the pc will jst shut off. i restart and everything is fine, im starting to think it may be a power issue, using a 750w psu, i think i need to use the 2x6=1x8 adapter and the 2x4=1x6 adaptor instead of the 6 and 2x4=1x8. might be better off to do that, i dunno, worth a shot
