strange artifacting?

okay i'm not 100% sure this is artifacting but the most common issue with this is that text get extremely disfigure in applications like discord and ocasioanally the window i'm focused one (not the whole screen) with loose basically all of the things on it being rendered by the gpu aside from things like wireframes and windows border around the actual window.
So usually I can fix thing like this on my own, most of the time it's a bad driver and i fix it quickly. Nope. I spent hours checking different drivers, different driver settings and yet I still can figure out what in the world is wrong with this computer.
It's a simple old gaming PC my friend brought in to me to clean and service since it was starting to run pretty hot and he has said that ever since he had the computer it had been having this issue. So I said I would clean the computer and then try to fix the issue and here I am two days later with no answer. 
The GPU is an asus RX 570, one of the strix cards. The processor is an A10-6800k which I put in about a year back because it originally had a A10-6700 and I have the 6800k laying around and just threw it in there for that extra clock speed since his board doesn't overclock (it does but its unstable). Not entirely sure Where to go from here, I will try testing it with a RX 590 I have or a 580 if I cant find which computer i left the 90 in.
The problem isn't that bad, at least according to him since it only happens when he has games open or the system is under about half full load.

I have some at home, and the screenshots don't appear to show the artifacting so I have to take pictures on my phone
