Recently I got an EVGA GTX 660 TI Superclocked 2GB graphics card. It wasn't performing as well as it could so I updated my cpu from an AMD FX 4100 to an AMD FX 8350. This fixed the problem immediately. I really didn't like the sound so I installed a corsair H80i. I didn't mess anything up while installing it. I also upgraded from an EVGA 500B PSU to an EVGA 750B PSU. The new power supply didn't have PCI-E to plug into the graphics card, but it had VGA which the manual said worked the same. The problems happened even in the old power supply so I don't think that's the problem. Can anyone tell me why this is happening, I have checked everything and cannot find the problem.
