QUESTION :
I am using Windows 10. I always leave my PC on sleep when I am not around and wake it up by pressing any key. This has worked fine until 1803, but in every subsequent Windows update after I put my computer to sleep and wake it up, the screen stays black. I can hear all the fans working and all the peripherals light up, but the screen stays in sleep mode.
Now I have been forced to upgrade to the latest update and I still have this issue. I thought that maybe it was because of the motherboard so I updated Bios. I have ASRock 870 Extreme3 R2.0
What could be the possible reason? Where should I start looking?

before modifying the registry.
