Help me troubleshoot please ;)

[Merry]

So in short, I was playing a game (LoL on 1080p, not intensive) when my main monitor (plugged to GPU) turned black, and my second monitor froze (to iGPU) while the sound was still going on.

I had to reset the computer, and it worked fine.

Later on, I go and have a smoke, once back the computer was off.
He wouldn't boot anymore (it'd turn on, but wouldn't go to bios nor beep).

So I took off the GPU (self-troubleshooting) and it ran well with the iGPU.

I cleaned completely my computer and it was fixed anew (it'd boot with the GPU in like normal).

Then the same shit happened today, wouldn't boot with GPU, without it, nothing. I cleared CMOS (just took off the battery) and it worked again.

Then later on it happened again, working fine after clearing CMOS for the second time today. And I'm here writing to u :
What do you think is causing this? I don't think I've got malwares, nor too many things installed, no overclocking at all, the temps are perfect ...
I tried and google but the only "troubleshooting" I've got told me that clearing CMOS might resolve the issue, it's just I don't know what's causing it.

Tyvm if you can help me out with this ^^

it may sound like the GPU is going to die

 

swap the GPU to the other GPU slot and see if that helps

 

update the AMD driver and pray hard it just software related
