So ,some funny thing happened : I was playing some World Of Warship and my pc just blackscreened, fan at max speed, and no response from my computer, but the sound was still working.
This happened yesterday, i restarted my PC and the problem was gone.
 
Today same thing happenned except now i can hear a "screeching" from my GPU.
See : (yt link can't post it)
It is 100% coming from my GPU, i unplungged it and the noise was gone.
 
I contacted the support but i bought that GPU way back when it came out in 09/2020 so the warranty is very much expired.
 
So now what? Should i try and repair it? should i contact a professionnal to get it repaired (and who)?
or wait for the new 5000 wich are wayyyyy too expensive now.

The noise you're hearing is most likely coil whine. That isn't a problem.

I'd highly recommend testing your video card in another known good working PC to verify that the card is indeed the issue that is causing the black screen & fans at max speed problem as a bad PSU could also cause what you're experiencing as well.

If the card works fine in another PC I would recommend getting a new PSU for your rig. If the card produces the same issue in another known good working PC then I would suggest having your card repaired by northwestrepair on YouTube.

That would be a VERY LOUD coil whine , but yeah i did not thought of that, well also the fact that i have no display confirm there is an issue here, i think that at least.
 
I'll try it in a friend's PC...in like a month when i'll be back...

 I've had a fan bearing screech before. with 3 fans it only takes one to make a racket .. i would look there first
