im having problems with my games freezing after 5 minutes of playing. i overclocked my cards and ran 3dvantage and it seems stable but doesnt seem to work playing games. could my power supply not be big enough for my set up. i also tried to up the cpu to 3.2ghz but it would never restart with that setting.
