Graphics driver 372.90
Windows 8.1
The issue
Okay, so the problem I am having is that when I play certain games. (Witcher 1, Doom 2016,chivalry) At some point, even in the first 5 minutes my screen will stop receiving signal and my graphics card and the fan will spin at maxed speed. This all started after I upgraded my GTX 760 2GB to a EVGA GTX 1060 SC 6GB.
What I tried and did not work.
I tried RMAing the card, I got a new card that was said to be hand tested to work. I put it in my machine.
Failed.
I tried uninstalling the drivers and tried different ones.
Failed
I tried reseating the GPU into the MOBO and made sure ALL connections are secure.
Failed
I ran the card in debug mode and it still
failed!
I even tried using different power connectors and a HDMI.
All failed
I tried a whole new card and it still did not work. So I ether got another bum card, or its my PSU?
What I noticed
My temperatures are fine. I even ran the fan on the gpu at 100% before starting the game and the same issue happened. This is not a temperature issue as far as I can tell.
In my bios the 12v rail fluctuates about 1%. It goes from 11.96v to 11.88v back and forth.
I passed every furmark test.
Overwatch and the Witcher 3 run fine with no issues.
Please I really need help with this. Should I just get a refund for the card? or should I risk not being able to return it and get a new power supply? I'm desperate at this point. All I wanted was to upgrade my GPU...
