Pixels appear on monitor just like that?

As you can see from the title of the question appear in my PC in most games such as: Rainbow Six Siege, Fortnite, GTA V, Counter Strike Global Offensive, Ring of Elysium, For Honor etc. Pixel, not just one pixel but several on once, and after the pixels have appeared, the game crashes.
It always happens in the above games, but there's one exception.
In Minecraft, I never get these "pixel errors"!
My guess is that the graphics card is not connected properly, as it is a finished PC from Amazon. It should be mentioned that it went all through June, I could play all the games.
My pc specs are:
GPU: Nvidia GeForce GTX 1050
CPU: AMD Fx (Tm) 6300 Six Core Processor
Ram: 8GB
Unfortunately, I can't comment on the motherboard.
I ask for reasonable answers
Kind regards

I add here again a screenshot of the monitor

Can you pay attention to the graphics card temperature while playing? Is that possible? From which temperature crashes the game, is not reached in minecraft such a high temperature?

Me

Aubacke. Finish PC with an FX CPU.

Well, what the hell, … Turn off the PC, remove the graphics card, insert the graphics card neatly again and then try again.

Me

If you have an internal GPU on the motherboard, you can also use it to see if the error will occur. (Of course you have to remove the video card).

Oh dear… An Amazon PC with FX and a 1050 … The combination is really total for the ton. Are all drivers up to date?

Yes my friend has reinstalled the drivers. Nevertheless, no change
