I have tried everything I could think of aside from getting a new graphics card. What normally happens is, I open a game (so far, any game like skyrim, elder scrolls online, black desert online, and saints row) and black squares (or squares that kinda distort the background) appear, and occasionally it leads to the entire game freezing up, showing a large colorful whatever that ends up crashing the game itself. Usually if the black squares show up in a game, it shows up on my browser, and other applications after I quit the game. And, in skyrim, when I look around, it seems like some textures are being stretched out. Here are a couple of examples:
I don't think it's my gpu overheating because with the games open, it goes to 54°C. I have absolutely no idea how to fix this, or even what exactly to search for in google. I would appreciate any help at all.
