Screen flickering in Windows is usually caused by a display driver issue or incompatible app. To determine whether a display driver or app is causing the problem, check to see if Task Manager flickers.
Press Ctrl+ Alt + Delete to open Task Manager. If you don’t see Task Manager after pressing Ctrl+ Alt + Delete, press Ctrl + Shift + Esc to open Task Manager.
If you're having trouble seeing your screen properly, you may need to start your PC in safe mode before continuing with further troubleshooting steps.
