Hey, i get the same problem with my BFG 9800 GX2. It isnt overclocked at all, but i maually cranked the fan up to 70%. GPUZ doent show any RPMS though.. But yeah, so i can play AoC everything max, but when i start Combat Arms (Closed beta) it just restarts the whole pc entirely. Is there a new rivatuner or GPUZ out since the begging of may im missing? I heard there was a driver for 5/31 and i cant find it. the one i have is from 5/2
