Your screen flickers or flashes at random times

Screen flicker is almost always caused by a display driver problem, a loose monitor cable, or the wrong refresh rate setting. A 30-second test with Task Manager tells you which one it is.

Your monitor is constantly receiving signals from your graphics card. When that signal has a problem — a driver glitch, a loose cable, or a mismatch in refresh rate — the screen flickers. The fastest way to figure out what's wrong is to watch whether Task Manager flickers along with everything else. If it does, it's a driver or hardware problem.
