Yep, the monitor was plugged into the motherboard, I didn't know that could cause trouble, but now it all works fine! Thanks.

I have done some things since I wrote this task, and after updating windows, blender gives me an unsupported graphics card OpenGL error, says it needs support for 3.3 or higer, but I have a RX570 wich should be more than enough, also if you still need the crash report here it is (Don't know if I did it right though), but I have blender 2.91 installed now.
