I recently built a new computer 600 watt psu i5 ivy bridge 3570k cpu z77 mother board and a gtx 650 ti. every once and a while my computer will have red flickering pixels on the screen. before this I had a radeon 7850 but I sent it back because of these red flickering pixels. I got my new gtx 650 ti long story and the flickering red pixels are still there. I have no idea how to fix this. Im thinking its my psu so I switched the PCI express cables for GPU and I have tryed different monitors.
