So basically what happens is that my pc freezes if i am in a call with someone they can still hear me... but my screen is in 1 fps. I changed my GPU a month ago. It was a used one it looked fine but now i think it might be broken. I dont see any drop in performance unless these 1 fps moments happen. It also happens when i close all my software and when i start my pc. I usually just keep Task Manager open to prevent it from happening and it works sometimes. It started happening after i changed the gpu so it must be the gpu... can i get some help please
