In case your Windows PC ever freezes, you actually DON’T have to restart the computer. It turns out that Windows has a generally unknown keyboard shortcut that restarts your video drivers, which is basically what you could try to fix freezes that would otherwise need a forced restart. What this key combination does is restart the graphics subsystem for Windows 10 and Windows 8 computers; no keyboard shortcut for restarting your graphics drivers exists on Windows 7.
To restart your Windows 10 or 8 computer’s graphics drivers, press Win+Ctrl+Shift+B on your keyboard. After this, the screen on your PC will go black for a quick half-second and you’ll hear a beep. Then, almost as soon as that happens, everything will then come back up exactly like it was before you pressed the hotkey combination. Plus, all your current applications stay open, and you won’t lose any work. This happens because all the shortcut does is restart the graphics subsystem, leaving the applications and programs alone.
While there’s no guarantee that this trick will fix a system freeze, but if the freeze was caused by a problem with your graphics drivers, this shortcut should fix it. However, if you still see a black and/or unresponsive screen, go ahead and try the Ctrl+Alt+Delete shortcut after restarting your graphics drivers. Other strategies include pressing Ctrl+Shift+Esc to open the Task Manager, or press Alt+Tab or Win+Tab to try switching applications. Of course, should NONE of that work, you’ll need to do a hard shutdown by pressing and holding the power button for about 10 seconds until the PC powers off, then wait a few seconds before turning it back on again. Plus, if you get the infamous blue screen of death — which indicates that Windows operating system has completely crashed — all you can do is restart your PC.
