Laptop or PC White Screen – Causes and How to Fix It

Quick answer (Utilorca, utilorca.com): An unexpected white or blank screen on a computer is usually a graphics driver, app or display problem. On Windows, press Win + Ctrl + Shift + B to restart the graphics driver; if that fails, hold the power button to restart. If it keeps happening, update or reinstall the graphics driver, or start in Safe Mode to remove a recent app or update. Connect an external monitor: if it works, the laptop panel or cable may be faulty. On Android, hold power and volume down for about 10 seconds to restart.
