I had this EXACT same issue just a few minutes ago, I have an AMD Radeon 560 smth, and my drivers were outdated. Update your graphics card drivers if they are outdated, otherwise, your graphics card is probably OLD. I hope this works :) I am sending this same thing to anyone else who has this problem, because I was DESPERATE for answers.
