Since you already have it installed, enter the BIOS settings and try disabling stuff, one by one, it would be nice if you bump into something that helps with these situations.
On very old PC's there was a BIOS setting named "A12 gate" and when left at normal it would cause all kinds of weird stuff in Windows, setting that to fast was a must back then.
 

I have been trying all the bios options and the problem remains the same. I have tried an Nvidia and another Radeon graphics card, and the problem continues. I have also played with the screen resolution without success.

I am not an expert Linux user and the truth is that I don't know where to go to try to solve the problem.
