Question Ryzen 3 3200g vega 8 one-color screen ?

Mar 27, 2021
Recently I have started to see single-color screens at random times on my monitor, most often it was the green, sometimes blue. Computer "under" the one-colored screen works normally. The only way to fix it is to reboot the computer or unplug the HDMI cable from the monitor (or motherboard) and plug it again. I have also another problem: when I watch some videos on youtube or internet pages, switch the app from the internet browser to some other application and go back to the browser I don't see the video, the browser is freezed (sound from youtube video is normally playing). I have to click on random places on the webpage and that makes the video appears. The same thing happens when the computer turns off the screen and I make it turn on again, for example by moving the mouse. What could be the reason for these things? Do I have damaged CPU with integrated graphics?

My setup:
Motherboard: Gigabyte GA-AB350M-DS3H V2
CPU: Ryzen 3 3200g
GPU: Integrated vega 8 graphics
RAM: DDR4 Patriot Viper 4 16GB 2x8 3200MHz
PSU: Corsair VS650
