Windows 10: Troubleshooting screens going blank but system is running

Hello,I need some suggestions on troubleshooting a problem. Randomly my monitors will go black and display signal lost. Windows is still running, and I can blindly shut down memorized keystrokes. After each incident the computer runs fine. I swapped out cables and monitors. I changed the ports the monitors are plugged into. I am up to date on Bios, Windows and drivers. I tried event viewer, but nothing seemed related.

FIX SCREEN SO IT DOESN'T GO BLANK

Hi Charlotte,



Thank you for writing to Microsoft Community Forums.



I understand that the computer screen goes blank after sometime, I’ll certainly assist you with this.



However, please let us know:

• Do you see any error message on the screen when the computer screen goes blank?
  
• When you say “I need to fix it so that doesn't happen” how are you fixing the screen?
  
• What is the make and model of the computer?
  

Meanwhile, you may want to refer the troubleshooting steps mentioned below:



If you are using a Desktop, then the first thing I would suggest you to do is check if the cables are connected properly.



Method 1: Refresh Graphics driver



I suggest you to try refreshing the graphics driver by using the key sequence
Windows logo key + Ctrl + Shift + B and see if that helps.



Method 2: Update graphics driver



I suggest you to try updating the graphics card driver and see if that helps. To do this, refer the steps mentioned below:

1. Press Windows logo key + X, and select
   Device Manager.
   
2. Expand Display adapters.
   
3. Right click on the display driver and select
   Update Driver.
   
4. Restart the computer.
