Win 10 problem after update

I’m currently running Windows 10 Home, Version 10.0.18362 Build 18362. I’ve checked windows update and it is up to date.

Yesterday, I came back to my PC and the screen was all yellow and nothing worked. Move mouse, press ESC, press ctrl+alt+del did nothing. I had to power off my PC and when I powered it back on it booted normally and ran fine the rest of the day.

Then when I came to my PC this evening, the screen was all black and nothing worked. I had to power the PC off and back on. After a normal boot, everything is working OK.

I need advice, if you have experience with this problem please help me
