Weird Black screen issue

[Jonilo5]

Hi!
Yesterday I got a concerning issue, my desktop doesn't boot. When booting up i get the bios screen, then the windows loading and then it gets black. The HDD led stops blinking after a little while too. This happened when I didn't have a monitor and no mouse/keyboard connected to it, since I was working with my other computer while this one was supposed to boot up, when I connected my monitor and all it was black.

I highly suspect it has something to do with my AMD GPU. I know this from WhoCrashed:

There was a crash log directly after but it contained nothing (Like it said "Custom error" or something with 0x0 as Bugcheck code). After I took this image I tried several things along side recover to an earlier date and I lost the logs and such

What I have tried so far:
* Windows safe mode - Almost worked "flawlessly" (aside from the fact that I couldn't open Windows update and internet issues)
* Recovery to earlier date
* Windows diagnostics
* Remove graphics drivers in safe mode

The last point is the most interesting because when I did that I could boot up as ordinary, for 2-3 minutes (with low resolution) and then my computer crashes and I get the black screen after I login on my windows account. Could that be a heating issue? But why don't I have the same time limit on the safe mode? (since I have used it for a much longer time than that).

I have no idea how to fix this

Edit:
After a weekend of investigation I have concluded that my GPU is allergic of GPU drivers now... Every attempt to install a AMD driver gave the same result towards a black screen crash.

Okay I used one DDU and removed all GPU drivers, it seems like I can boot into windows "normally" BUT every time I install a new (or old) driver I get the same black screen crash. Is my GPU dead after 6 years of light workload? 
(I barely played on it and finally got Valheim last week.. )
