I've seen this posted up multiple times, but haven't found an answer to my problem. I get the black screen restart on a build I just made. I've only had it a couple of days, and on the first day everything seemed gravy. I kept it on all night downloading games from Steam with no problem. I go to play Company of Heroes (a must for any RTS fan) and ten minutes in my PC goes black, then it shows my GPU specs (which it does regardless), then starts normally again (asking if I want to go to BIOS with the delete key) and everything. A lot of people on here said it could be heat. So I installed HWMomitor and CPUID HeavyLoad to stress test. When I stressed the mobo and CPU the CPU was hitting 67c (70c being the max it's set at) and the North bridge was also hitting 67c. The other parts of the board were between 37-54c. I found it was in OC genie mode so I turned it off. CPU now runs (under stress) at a constant 57c during the hour long stress test. The North bridge still at 67c. I stressed my GPU (using CPUID) at 3k fps for 45 minutes with no heat problem or failure. It ran fine. No black screen. I started to play a flash game and noticed my sound wasn't working (I figured becuase I didn't have speakers) so I plugged in speakers in all holes but mic (nothing happened) until I plugged it into mic and it black screened. My BIOS us up to date via Live6 and I've tried this using both Win10 64 pro and Win7 64 pro (both up to date) and my GPU is up to date via nvidia program. I tried adding the audio drivers and I got an error saying it wouldn't work. Any help would be much appreciated.
