Windows 10: Black screen just before logon screen windows 10

I'm having this strange and annoying behaviour that makes me waste a lot of time and I cannot identify the source of the problem, maybe someone can help me.
The pc starts booting, the loading circle goes around with on gigabyte logo screen and when finally the logon screen should appear the screen becomes black, and everything unresponsive, no mouse, no keyboard!..
This is happening frequently lately, some other times it boots just fine.
I hit the reset button and it goes to the black screen again, and again, and again... and sometimes it boots, sometimes it never boots this way.
When Windows goes to advanced boot options, then if I select option 1: Debug mode. the pc boots up normally... about 50% of the times.
In advanced options if I select recovery mode it always boots. Then I end up cleaning the GPU drivers with DDU and the pc boots ok. windows reinstalls GPU drivers automatically and the probability if a black screen is HIGH!
In advanced boot options if I select low resolution mode the pc almost always boots. That's how i'm in the PC right now.
I've done all kinds of updates, to BIOS, drivers, software, bios options etc, nothing seems to solve the problem.
Sometimes at pc power up I have a black screen also and I have to reboot.
I don't know if this is the GPU, motherboard CPU, or drivers problem.

How can I debug this? Anyone else had similar situation?

I'm on windows 10 version 1809.

Black Screen Isuue in Window 10

Hi kashish,

I would appreciate you for trying troubleshooting steps.

To understand the issue better, I request you to answer few questions:

• Does black screen appear when you before user login’s or after user has logged in ?
  
• Does black screen appears when you lock your pc?

This problem occurs because of a change in the behavior of Win Logon and Logon UI. This change introduces the potential for the deadlock.

I would also suggest you to install all the updates available for the system and check if it helps.

Follow the Below steps:

• Type settings in the Search area on the taskbar and select Settings
• Select Update and Security.
• Click on Windows Update and select Check for Updates

Keep us posted with the status of the issue. We’ll be glad to assist if you need further assistance.

Thank you
