Win server 2012 black screen after logging

Mohamed Hemida 21 Reputation points

I have win server 2012 I am using it for sun material app.
a week ago I started to face the black screen after the logging and I can't do anything or management the server except through safe mode despite the app running properly .
I did the following to solve the problem but I didn't find anything wrong:
1: Running Dism /Online /Cleanup-Image /CheckHealth
2: running SFC /SCANNOW
3: bootrec / fixmbr
4: bootrec / fixboot
5: bootrec / rebuildbcd
6: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon (Shell key)

Although I found this error in the event viewer and repeat it self continuously :
DCOM got error "1084" attempting to start the service ShellHWDetection with arguments "Unavailable" in order to run the server:

Any help.

    I had something similar and it was a profile related issue.
    If it's domain joined try creating a new user with no roaming profile and see how you get in.
    If it's a standalone box, try another account (if you have one) or let me know if you need help with trying to create one.

    Welcome to Microsoft Q&A.
    Check if there is a memory.dmp under C:\Windows folder.
    If there is a dump file, you can download the WinDbg Preview from Microsoft Store for dump analysis.
