GPU stopped working, black screens

[Cioby]

So I just turned Escape from tarkov on again, didn't even play, just went to my base/stash, suddenly everything went black and I could still hear my PC works. Since I couldn't open task manager I forcibly rebooted my PC.
Then the monitors remained black. Works with other GPU, older 6+8 pins not 8+8, works with integrated GPU.
The fans don't start and neither does any of the lights.

It's a 5-6 years old 1080ti Aorus.
Anything else I can do or where can I sell it for parts, they buy new 2000 and 3000 series but not 1080ti. Personally I think that the fans just no longer work or some small piece might've died.
