Question PC james while gaming - possible psu or graphics card related problem.

[-Ik-]

Well,
This "condition" started a while ago (maybe a year) but recently it started to be outrageous and unbearable.
While playing R6 , it suddenly turns into a black screen and the sound james. From that point on, I have to press the power button and restart it, and than all goes back to normal. I have observed that it is, or at least was, enough to keep the fans at maximum power, and the GPU at a temperature below 50 degrees Celsius. I don't think it's a CPU issue, since I ran some benchmarks and all went smoothly. The problem arose when I ran a GPU benchmark ( black screen and sound jam). So I decided to change my GPU thermal paste. The problem persists and seems to repeat more and more.
Recently it happened while playing Disco Elysium (not particularly stressful game) beacause I forgot to turn the GPU fans on.
Any fix?

That's not a PSU problem.

Might have found the solution; I underclocked my gpu from 1040 to 1000 and also increased the power limit by 10%; I ran the benchmark again. ATM all good. I don't know how and why this works, tho. Needs some more testing.

Nope, no good. It still crashes.
