Please try pressing the Windows key + Ctrl + Shift + B shortcut keys simultaneously on the keyboard to force a reset of the system's graphics driver.

If the system receives the command successfully, you should hear a beep or see the screen flicker, and then the display will return to normal.

Common Q&A

Q1. What is this shortcut key?

A1. Windows key + Ctrl + Shift + B is a built‑in dedicated shortcut for Microsoft Windows systems. Its main function is to let the system restart the graphics card driver directly without rebooting the computer.

 

Q2. Why does a black screen occur, and why do we need to do this?

A2. There are many causes of black screens in Windows, including frozen Windows processes, issues with the graphics card driver, incorrect display output settings, etc. This shortcut forces the system to refresh the display signal and effectively fixes black screens caused by driver crashes.

 

Q3. Where or under what conditions should I use this key combination?

A3. Besides waking from sleep mode (S3), you can also try this shortcut first if you encounter a black screen at startup, after login, or after a system update to restore the display.

 

Q4. How do I confirm the operation was successful?

A4. After pressing these four keys at the same time, if you hear a beep or see a brief screen flash, it means the graphics driver has been successfully reset.

 

Q5. Will using this key combination restart the computer?

A5. This key combination will not restart the entire computer.

 

Q6. Are there any limitations to this key combination?

A6. This shortcut only works for black screens caused by graphics driver errors. It cannot fix issues such as loose cables, monitor power failure, or other hardware problems.If the screen remains black after using this shortcut, we recommend pressing and holding the power button for 25 seconds to perform a firmware reset, or entering Safe Mode to update or roll back the graphics card driver.

If the black screen issue still cannot be resolved after trying the shortcut, please contact the MSI service center.
