Black screen for 4 -5 min after boot WIN 1021H2

Victor Valencia 1 Reputation point

I have a recent issue with my laptop taking about 5 min to show explorer after login. During that time its stuck on black screen. I searched some forums and at first thought that it maybe be my NVIDIA driver. I however reinstalled it and have the same issue.

I saw this question asked on another threasd in technet and the suggestion was to check in if Registry Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon, shell is set to explorer.exe. I can confirm that it is.

I am able to run task manager and have tried to manually start explore.exe but have no luck it still takes 5 min for desktop to show.

Running a DELL G7 7770 32 GB ram. with a Geoforce RTX 2020 super on driver version 472.47. Windows version 10.0.19044 Build 19044

I also tried to roll back the latest windows update just in case. No luck

    1) When there is a black screen click these 4 keys simultaneously:
    Win key, ctrl, shift, b
    Report the findings.

    2) Uninstall any third party antivirus and make sure Microsoft defender is on.

    3) Place the computer into clean boot:

    4) Indicate how you reinstalled the Nvidia driver, nvlddmkm.sys:
    (method and source for the replacement driver)

    5) Indicate whether the computer has Nvidia Optimus:
    If it does was the Intel GPU driver replaced?

    6) Open the Dell website support > enter the service tag > view drivers > upgrade the BIOS or confirm that it is up to date

    7) Run the Dell diagnostics > full test > post images of the results or share links into this thread

    Do you face the same issue in Safe mode?
    If not, boot into Safe mode and uninstall the graphic card driver. Once done, reboot and update the same.

    Thank you for your question and reaching out.

    1. Its probably issue with Graphics divers , try to upgrade drivers with older stable version.
      Also , try to change display resolution to lower
    2. If you have added Graphics card then try to remove it and use built in onboard Display driver.
    3. Disable any Antivirus program or Windows firewall you may have for temporary purpose.

    4.Cleanup below Temp folders
