Recently I bought a new PC, everything worked very well and all. But a couple of days ago, I noticed that when I was playing games, random black or white lines would appear on anything that was moving on the screen. I don't have this problem when I'm using Firefox or watching videos, just when I'm playing games.

Plus I have a Radeon RX 580 8GB GDDR5 graphics card, and a Thermaltake TR2 S 700W 80 Plus power supply.
This is how the task manager appears when playing games:
And this is an example of the problem I have:
