PC bluescreens and sometimes crashes without BSOD

Hello.

For quite a long time I've had a problem with my pc where it at random times crashes sometimes with and sometimes without BSOD. I've tried a lot of things and gotten advice from some people over at Tom's Hardware Forum, who also asked me to post here as they might've missed something.
Here's a link to that thread: Question - PC bluescreens and sometimes crashes without BSOD | Tom's Hardware Forum

My Windows version number is 1909.
Here's the V2 Log collector file you asked for: RYZEN-(2021-01-16_14-39-37).zip - Google Drive

Here's my latest BSOD. There's some new error codes I haven't seen before.

Hello VitusB,

I'm afraid your WIndows installation does not have a valid license. We are therefore not able to help because of our Forum rules.

Ah okay I see.
I've reinstalled Windows a couple times and must have forgotten to activate it this time - I'm sorry about that, I'll activate as soon as I can. Afterwards do you then need a new V2 log collector file, to confirm that I have a license?

Yes, we will need to see the new logfiles for confirmation.

Here's new files with activated Windows: RYZEN-(2021-01-17_15-36-56).zip - Google Drive

Thanks for the updated files which confirm you are correctly activated.

The crashes seem to be associated with the graphics system and possible indicates the AMD driver installed (DriverVersion: 27.20.14501.28009) is not the best for your system.

Can you try some older versions?

Uninstall everything of AMD using Display Driver Uninstaller and install drivers from your Graphics card manufacturer. When you do this be sure the "clean install" box is checked and only install the Graphics driver for now.

I've tried this some time ago, but I can try again if it's necessary.
Here's a post which sums up what we've tried so far: Question - PC bluescreens and sometimes crashes without BSOD | Tom's Hardware Forum

I will try and work through that thread - it may take me some time.

Colif from Tom's Hardware Forum wanted me to tell you that you can just read this post to get a general idea of what has been tried: Question - PC bluescreens and sometimes crashes without BSOD | Tom's Hardware Forum

That was helpful. You have already tried just about everything but a CPU replacement. It looks like the conventional approaches have not worked and possibly the hardware fault is not being picked up by diagnostic tests. Passing the CPU test is not always a reliable indicator. Is there anyway you can get hold of another CPU to test with? The graphics system and the CPU are inter-related so it kind of fits.
