Windows 10: Black screen, keyboard unresponsive, requires PSU off/on to restart

Microsoft Windows 10 Version 1909 (OS Build 18363.719)

Occasionally, not seemingly connected to gaming or any particular activity (sometimes even when computer is idle), my monitor will cut out, my keyboard will freeze up (eg cannot toggle NumLock), and the power buttons on my desktop case will not be responsive.

The fans in my PC will continue running as usual and power will remain on.

The only way I can restart the computer is to shut off the PSU power switch. The power buttons on my case are not responsive.

I don't know how to reproduce this crash. I cannot verify whether it is a true BSOD or something else because the monitor does not work. Unplugging/replugging does not help.

This is a custom built PC. Exact parts listed here: Ryzen 2700X - Ryzen 7 2700X 3.7 GHz 8-Core, GeForce GTX 1070 8 GB FTW Gaming ACX 3.0, Phantom 630 ATX Full Tower - PCPartPicker

LCD is connected to the GPU via a displayport cable.

Hi Tony,

As the screen goes black I suggest you to refer the Microsoft article on

I also see that you are facing issues with the keyboard this might be due to the corruption of keyboard drivers. I suggest you to run the
hardware and devices troubleshooter and check if it helps.

Follow the below steps for the same.

• Change the view by option on the top right to Large icons.
• Click on troubleshooting and click on the view all option on the left panel.
• Run the Hardware and devices troubleshooter.
