Windows 10: Windows 10 black screen -before- login screen problem.

    Windows 10 black screen -before- login screen problem.


    I upgraded a desktop computer from Windows 7 ultimate to Windows 10 and there seems to be an annoying black screen issue which happens before the login screen.

    After the Windows loading logo, the screen stays black for about 60-80 seconds (and all I can see is the mouse cursor). After 60-80 seconds, the login screen pops up and everything works fine and I can login.

    I already tried the following:
    - Updated NVIDIA drivers
    - Completely removed NVIDIA drivers to see if it was a drivers problem
    - Booted into safe mode, still happens
    - Checked event viewer, nothing weird in the logs
    - Made the PCIE slot the default slot for the primary monitor in the BIOS
    - Ran the sfc /scannow command, no violations found
    - Ran all Windows updates
    - Took a look at the services and startup processes, nothing weird here
    - Turned fast boot off/on, no change
    - Full Malwarebytes scan, no infections found

    I ran a xbootmgr trace log, here's the summary XML file: processSummary numProces - Pastebin.com

    Could anyone help me out?
    I'd like to keep the fresh installation option as a last resort.

    This is a issue for a lot of us and doesn't seem to be any fix for it right now.

    I have the same issue with you, but my laptop uses AMD card. Did you try to disable auto switch graphics in BIOS?
