PC display won't turn back on after screen inactivity timeout.

Question

PC display will not turn back on after i leave my computer for awhile (over 5 minutes until screen turns off) This issue does not happen every time, sometimes i will go to have a shower and i can come back 30 minutes later, move the mouse and the screen will turn on and work. Sometimes i can go away 5 minutes to grab a drink and come back and it will not turn on (Random times and intervals) When i do return and click the mouse or keyboard to wake the display the backlight will light up and display 'No signal' then turn off again. I can see the PC is running based on the lights and fan running. I have tried to unplug and replug my keyboard mouse and displays to troubleshoot with no success, my devices are enabled to wake the pc. I have tried using differant cables and ports. Im running a double monitor and it doesnt seem to be a monitor issue as i used these monitors with my last pc. i have tried reseating the GPU and RAM. Unplugging and replugging does not work and just displays the same ' No signal' The only way around this for me is to manually turn the PC off everytime with the long press power button on the casing. I have performed a clean windows installation. I believe the problem may be in my settings somewhere but i have no idea.

Answer 1

Check these settings:

Settings → System → Power & battery → Screen and sleep

Set "Put the device to sleep" to Never temporarily just to test.

Make sure only the screen is set to turn off, not the computer.

In the same advanced power settings, find USB settings > USB selective suspend setting and set it to Disabled.

Update Graphic card driver as well as chipsets of motherboard.
