The error file shows numerous references to the radeon component, along with for example: "[drm] GPU HANG: ecode 8:0:0xffdffffe, in Xorg [539], reason: hang on rcs0, action: reset".
This appears to show some issue with the radeon GPU, even though you say that your "AMD Radeon R5 M330 is switched off".
I would physically remove the radeon component, then see if the issue remains.
If the issue has gone, then, if you can, try swapping the existing GPU with the radeon, and try a similar restart.
If the GPU is built in to the motherboard, then you may not be able to do this, and simply be out of luck.

If the system works well without the radeon GPU, then the question for you to answer for yourself is "Is the radeon GPU needed?". If the answer is no, then problem already solved. If you do need it, then you might have to consider a different physical environment for all the devices, eg a new rig of some sort with different motherboard, etc. You would need to research the components for compatibility, etc first before committing of course.
From all the descriptions of the issues, I would suspect a motherboard issue with properly recognising and using the radeon GPU.
I hope this helps.

After I read post #3 my first thought was OP is probably a 'h4x0r' or '1337-l0rd'. So I just leaned back and enjoyed the show as it unfolded. I did not comment back then since I gave OP the benefit of the doubt. Looks like my initial impression was not wrong.
I specifically liked this part:
I bet it took OP a lot of restraint to not write 'my mad hacking skillz'
