Problems with amd radeon rx 5600 XT video card after installing 20.9.1 drivers?

Question

Drivers

Can someone tell me such nonsense started after installing the drivers. From the first time the computer does not start, sometimes there are artifacts on the screen. Further, after the reboot, the screen starts at a resolution of 600 by 400 and nothing can be changed, then I reboot the third time and everything is fine and in the notification tray it says that the video card settings have been reset to the user type. It was a week ago that reboots didn’t help at all, rolled back the driver, it became normal, then again the situation described above, rolled up the driver, I don’t know what to do.

Answer 1

The computer does not start in what form? Are the fans and lights on and just a black screen? does it have sound? keyboard on?
