Mac OS is suffering for no reason. Icons and inscriptions disappear. What to do?

Question

macOS

Welcome all. The system has recently begun to be incomprehensible. Sometimes the sound will disappear, sometimes the sound will be very quiet at max. volume, sometimes some artifacts for a second when opening the lid of the macbook. Now I don’t understand at all that when I open a video on YouTube, it opens 1/4 of the screen in the upper right corner and the rest of the place is filled with white. After 10-15 minutes, for some reason, the icons began to disappear and it was not clear what was happening. Reboot heals, but not for long. I am attaching the screenshots that I did. (Even the desktop picture is gone!)

(PS Look at the bar, everything seems to be more or less ok. Sorry for these top glosses of course)

(PS Now the inscriptions from the navigation have disappeared altogether)

(PS It’s already started again, it’s not clear what)

(PS Screen from safari)

(PS Look at the bar, charging is gone)
In general, I don’t know what to do and what is happening. Help. Macbook Pro 2017 13, 10.13.6.

Answer 1

make a backup with a time machine and roll the system over again, look at the behavior on a clean system.
if it repeats on a clean one - just bring it to an authorized service. The warranty for PCT MacBooks in the Russian Federation is 2 years, and unlike retail chains, authorized service providers know this.
and so - imho resembles a problem with the video
