    Black Screen Delay Before Login


    **link to video of my issue at bottom**


    I built my first pc. I upgraded to an aio from an air cooler and after putting everything back together, I get a long black screen before i get to the login screen. It takes almost a minute before i get to the login screen. It used to only take 3-5 seconds for that screen to come up. I have Windows 10 Pro living on an m.2 so it should be pretty quick.


    Troubleshooting steps i have tried:

    - used a different monitor

    - Used differemt display port cable

    - Used hdmi

    - Reseated gpu

    - Reseated RAM

    - Reinstalled graphics driver

    - Checked bios for initial display output

    - Checked boot order

    - Restored to a previous backup point

    - Uninstalled a program that goes along with aio evga flow control

    - Disabled all start up apps

    - Unplugged all peripherals except mouse

    - Checked for updates and everything is up to date


    I couldn't boot in safe mode because once i get to the bootup options, my keyboard doesn't work for some reason so i can't select one.



    Nothing has worked so far and it is super annoying. Any help is appreciated!

    Here's a video to my issue since i can't upload one onto here:

    After POST, Extended Black Screen Delay Before Windows Login

    I think your slow login is caused by the fact that Windows is making too much time to load your user profil, probably because of your Webroot antivirus !

    the logon phase took 37s

    when looking at the call stacks for details, you can see that the system is loading the user profile (duration = 36s)
    and at some point in the stack the webroot AV is doing some scanning stuff !

    What you can do:
    • Create a new user and try to log in your system with that user profil to see if you notice the same delay;
    • empty the Temporary folder inside your profile [c:\users\your_user_name\Appdata\Local\Temp]; I've seem many logon delays caused by a voluminous Temp folder.

    I hope this will help.

    5 min delay on cold start between login screen and bg screen

    Ok, let the powershell command run overnight
    If the command didn't solve the problem, the try these steps in order:

    1. Disable superfetch service
      • Empty the following folder c:\Windows\Prefetch\
      • Restart the computer
      • Si ça ne marche pas, passer à l'étape 2;
    2. Disable the AppXSvc from the registry: change the "Start" key value from 3 to 4 (see the screenshot)
