Graphics card not displaying

[Gotato]

System:

MSI Z170A 

GTX980

6700K

Corsair hx 850w

Hyperx 16gb ram (8x2)

Samsung 950 boot drive

(2x 1b HDD)

 

So just last night whilst in game I had an issue where my graphic card would just stop displaying. I could hear and talk to my friends on discord and hear game noises in the background, this happened everytime the GPU was under load (I tried with furmark). So thinking it was the GPU, I put it into a working computer and it ran perfectly (even stress tested furmark). Next I thought maybe my psu was the issue (I had learnt my psu was 'leaking electricity' or rather it was possible). But when I used a working PSU in my system I still have the same issue. Is my motherboard the issue? Or could it be something else?

Try to use DDU to uninstall the drivers and then reinstall them. You can take the card out and use integrated graphics to uninstall the drivers.

I've been trying to do this for the last hour. I'm not getting a boot screen no error codes and it seems to be fine (I even changed monitors). I tried shorting the thing to clear CMOS and also removing the battery for almost 10 minutes. Even so far as to completely remove the GPU from the system. Still no display.

 

(I did disable the igpu montior function in bios which is why I wanted to clear CMOS to be sure)

Try changing the video cable as well and test the cable+monitor with another device. If you clear CMOS, take the graphics card out, and still don't get output using onboard graphics with a known good video cable and monitor, then I don't know what to suggest further, your card might be bad.

I did change the cable and monitor to known good ones. Still no display. The thing is I know the card is good because it worked in another system. I heavily assume mb dead. But after trying multiple different pcie slots and still running without display I'm kind of lost. I might take it to a repair shop at this point as I'm also stumped
