And no, it’s not CTLR + ALT + DEL. Windows has many keyboard shortcuts, most of the best known are focused on productivity, i.e to do things faster and simplify repetitive tasks.
But, one that maybe not many people know is the Windows keyboard shortcut to restart your video drivers. If you happen to have your computer hang up, it’s a good idea to try this shortcut before giving everything up for lost and rebooting in a forced way.
The combination that works only on Windows 8/8.1 and Windows 10, restarts the graphics subsystem and in many cases can turn your PC to life on a crash that seems definitive.
You just have to press Windows key + CTRL + Shift + B. The screen will turn black for an instant and you should hear a beep. If it is successful, everything will appear as it was and you won’t have to restart the computer losing your job because you hadn’t saved it.
Pressing Windows key + CTRL + Shift + B Restarts the drivers of your graphics card.
It is especially effective if the crash occurs when you play a game or you were working with a video editor or other program that uses resources from your GPU. The shortcut is an integral part of Windows 10, and it works to restart both the Intel, NVIDIA, and AMD video drivers.
If the shortcut does nothing in your case, the hang-up is probably not related to your graphics card. There you can turn to the old and known CTRL + ALT + DEL and see if the system reacts and lets you open the task Manager to kill the processes that do not respond. If that doesn’t succeed, you only have to press that reset button or you will be forced to shut down the laptop.
