I couldn't think of anything else to title this. Lately since I've had my PC formatted every YouTube video I watch has this thing. It's kinda like changing the quality back to 240p and then back to 360p, except it's not actually changing. I don't know how else to explain this, it's like the video quality constantly going back and forth from good to pixelated. I've only noticed this on YouTube so far, but I figured this would be a graphics card problem because I know it's not my internet, and it's only been happening since I got it back.
