I oced my gpu to 815/2022/1220 and i thought it wasn't too high for a card like this but 10 minutes ago i was playing NFS undercover and the game started to stutter then it froze after 2-3 secs the comp crashed and gave me a BSOD!! I restarted the comp and got back into windows. Took back the oc and played the game again. It played fine. It was a little slower than before but fine. I oced it a couple of days ago and everything was fine up until now. Temps are normal. 78 Underload (Is this normal?) and 60% fan speed. Is my gpu dead?
