Hi Dunly: Thank you very much for joining the Intel® Processors communities.
Not sure if you already installed the drivers below, but we can try to re-install the chipset driver of the board:
And install the latest graphics driver from Nvidia:
If you do that and the problem with the games persists and the processor still fails the PCH test, then there might be a problem with the processor itself.
This problem, is it recently or it happens since the first day?
Do you have the option to test the PC without the video card and using the Intel onboard video?
Do you have the option to test your processor on a different board or test your board with a different processor?
Any further questions, please let me know.
