Display drivers are frequently to blame for screen flickering in Windows. To upgrade your display driver, start your computer in safe mode, remove your current display adapter, and then check for driver updates.
-Start your computer in safe mode, then right-click Start and select Device Manager.
-Choose and hold (or right-click) the listed adapter, then select Uninstall device. Select Delete this device's driver programme, then Uninstall and restart your PC.
-After your computer has restarted, hit the Windows logo key + I on your keyboard to access Settings. If that does not work, go to Start > Settings.
-Select Update & security > Windows Update from the Settings menu. Check for updates and install any that are available.
