Lately, grey rectangles and squares have been forming all over the screen. They move and flicker, sometimes they're not present at all. But it leads me to believe there's a GPU or monitor problem here. I took a screenshot of it with print screen and it did not show up. I took a picture of it with my phone (2) and you can see how there is movement. It especially moves or forms when I move the mouse or move windows.
Let's say the laptop isn't under warranty anymore, what can I do here?
