Question Is my GPU dead?

Hey everyone! I haven't been on this site in years, so I hope I'm posting in the right place (if not, feel free to move it).
I think my GPU (Sapphire Nitro R9 390 8GB) has died, I'd just like to hear your thoughts on whether that's really what's going on since I haven't really done any troubleshooting in a long time. I guess I'm hoping for some miracle. Here's what happened:
About two weeks ago, my PC started suddenly getting black screens and freezing - sometimes with whatever audio was going on at the time stopping immediately, sometimes it lasted for maybe a minute until I tried to click something (with a black screen). There'd be a sudden cutoff with some kind of short audio distortion. Most of the time I'd have around a dozen chrome tabs and a few programs open, maybe a non-intensive game. At first I thought something was going on with the RAM, since someone mentioned it could be overheating, but I was in the middle of my exams and didn't have time to check. The only thing that would solve the problem was forcing the PC off and turning it back on again - which temporarily fixed it until it stopped working again. I tried to reset the RAM overclocking profile to auto, because ever since I built the PC I'd get an overclocking failed error on boot once every couple of months. Didn't help.

Yesterday, I was playing Shadow of the Tomb Raider, performance was great, nothing out of the ordinary, and it happened 4 or 5 times, sudden black screens with no way to interact with the PC, frozen, and each time I'd have to reset the computer. I kept an eye on the thermals and load, everything seemed fine. Finally, it refused to turn back on.

Today, I started troubleshooting, trying to disconnect different parts one by one and see what works, making sure to reseat them properly; the RAM, GPU, even cleaned the CPU fan heatsink and applied new thermal paste etc... I even tried changing the PSU/GPU power cable. I can't try another PCIe slot because the card is too big to fit, the hard drive bay is in the way. It finally booted when I connected to the integrated GPU on the motherboard. The GPU fans aren't spinning, can't see it on the device manager. So I think it finally died on me. Right now I'm running DisplayPort from the motherboard with only one monitor instead of my usual two, and I'm feeling a bit hopeless - I can't afford to get a quality replacement atm. So I guess my dreams of gaming during my break in-between semesters died before it even started.

The GPU is old, and it was starting to show its age with regards to in-game settings. I bought it new back in 2015, so it's lasted quite a long time, I know, but up until this point it was still performing flawlessly.

System specs:
i5 6600k
R9 390 8GB
2x8GB Corsair DDR4 (can't remember which model but can find out if needed)
Corsair Vengeance 650M PSU
ASUS Z170 Pro Gaming Motherboard
Windows 10 Pro x64bit, build 19043.1466

Thanks for any help or insight.

How old is the PSU in your build? Also you have updates pending for your OS. BIOS version for said motherboard listed above? The 390's were known to be room heaters(like all their older gear, from AMD), might want to see if cleaning the GPU thoroughly helps alleviate any issues, thermal wise.

The PSU is about a year old (the previous one was a 750 bronze that started producing smells of burnt plastic, so I replaced it before it could do any damage). The 390 is indeed a room heater, I don't know how much cleaning I can do without taking it apart though. I blasted it with some compressed air to get out some dust but there's still dust visible.
As to pending updates, I'll check and get back to you on that.
 
Windows is updating, last BIOS update was "BIOS Version/Date American Megatrends Inc. 1102, 16-Nov-15" according to msinfo32, latest version is apparently Version 3805 from 2018/05/25.
Should I update? Any chance a specialist would be able to diagnose/fix the GPU? Or are they too hard/expensive to repair?
 
Well, I'm gonna guess it's dead for good. The motherboard can output to two monitors, so at least there's that - the PC is functional, more or less. I just won't be able to game until I can get a new GPU. Might as well be a bit more productive, or get through my console backlog...
I've been considering the RX 6600 XT as it seems to be quite an upgrade and in my country, even though it's ridiculously overpriced, the higher tiers (which I'd prefer to get) are even more so, and the RTX 3060 TI is like $300 more expensive... in any case I think I'll wait a while until I make a choice.
