Hi NikolaiTheMinecraftGuy-5356,

This looks like a hardware issue. If your PC has a built-in graphics card, please connect your monitor to that instead of the GTX card. If this doesn't have the same issues, it's likely to be your graphics card with the issue. If there's no improvement, then it would be worth giving the PC a good physical clean out, if it's dusty etc as overheating could be causing what you're seeing.

I hope this answers your question.
