Sup guys. Here's the problem, since yesterday my GPU has been acting weird. I had it clocked at 850MHz but strangely enough didn't notice any fps increase in any of the games. I downclocked it a little and found that the GPU wasn't stable at those clocks which ticked me off. Since then i have the GPU at default yet im getting all kinds of hard freezes during graphically intense stuff like GPU tool stress testing. The only change i remember making is updating the GPU drivers. The card was running okay on a 250w psu but the freezes were too many. I got my CX430 PSU 2 days ago and it stopped the freezes until now. any idea whats going on guys?
