A couple of months ago, after the next update of Windows, when starting the laptop, all the inscriptions in standard programs disappeared. Time and date in the taskbar, the indicator of the selected language (except ENG) - all this is gone. It feels like the fonts just didn't load. For example, in Explorer and Control Panel. Just white flattened fields.
After a couple of hours of searching, by typing, I noticed that if you run some heavy program, then all the inscriptions will return with a high chance. Khrunovo, but you can live.

Yesterday, all of a sudden, the keyboard just stopped working. All, just in the middle of typing.
I found it in the device manager, it says that everything is ok. Drivers are also up to date. On the manufacturer's website there was advice to remove it from the list of devices and reboot. Did not help. Probably hardware, esc doesn't work on restart.
Connected a wireless keyboard, works fine.
Also, today, when creating a folder on the desktop, the process crashed with an unknown error, and half of all the folders on the desktop got mixed up and renamed to the one I wanted to create.

I don’t feel like bringing it in for repairs, but I need it, so, of course, I’ll take it to the extreme. What to do?

Answer 1

Check your RAM with Memtest. It comes standard on Windows: https://remontka.pro/test-ram/

If you want to solve the problem without dancing with tambourines, I advise you to rearrange the OS to start, such misunderstandings often happen precisely because of Windows. 90% that should help.
Hardware problems do not give such side effects.
