Hey. The rx470 video card is connected via HDMI 
to the monitor. After starting the system unit,
a gray background with a purple rectangle appears
on the monitor. Then the Asrock logo appears from
the blurry pixels. Then one beep is heard. After that,
the screen turns completely purple and the computer
restarts and so on two or three times. Then a window
appears for entering a pin code, sometimes it is
normal, sometimes in inversion colors. If everything
is fine, then the entrance to windows 10 occurs.
According to Furmark, the temperature does not rise
above 71 degrees Celsius. In games, everything is
fine, it does not crash, there are no artifacts.
In windows errors, this is saved:

Drivers set different, from old to the newest.
I hope the coronovirus is unacceptable.
How can I fix this problem?
