Hi, I have bouhght a new hardware: GIGABYTE GA-Z77-D3H - Intel Z77 (ver 1.1 bios F18) + cpu i5-3570k + ram crucial Ballistix 2x4gb 1866mhz cl + nvidia geforce gtx 560. Power supply is 4 years old Seasonic 550W
I have problems in games where after 30-60 minutes the PC completely shuts down and then restarts. I have Bios set to default values, I tried to stress test the processor and ram, which ran for two hours without a problem. CPU temperature is around 50 ° C. It also undertake a video compression to h.264 for 7 hours without any problem. For general work in Win pc never crash.
Problems are only in games (any). I have the latest graphics drivers. Yet I see conflict somewhere between the motherboard and the graphics card. A memory problems usually result in a system lockup or blue screen, not turning off the PC...
Integrated graphics in the cpu is disabled, I also tried to BCLK frequency 100.1 and disabled c3/c6 state on the board.
