Hi guys its the main rig in sig. Last night I was in a mw3 server waiting to rdy up and my screen went black and machine froze but stayed powered on. I had to do a hard restart. It ran ok after that but after the screen went black the monitor displayed a message saying no video. Ideas? I have the cpu voltage set to 1.4 volts and it passed prime95 for 5 hrs. I ran memtest latest version on the ram kit and it made 2 complete perfect passes. At this point I am wondering about the gpu, its a Gigabyte Windforce, which is running @ stock. I am running the latest drivers for the 570 296.10 as per the nvidia site. Cheers TIA!
