    Windows desktop screen goes black after a few seconds of logging in


    I was using my computer as normal on Sunday 3/11/18 when around 6:30pm the sound stopped working. About an hour later, I had been able to do other stuff on it. Later on that night, I went to restart it only to find out when I did, the internet was no longer connected and I couldn’t open the start menu or anything else. I also got this message when trying to resolve the internet issue: “The Diagnostics Policy Service Is Not Running”, but I wasn’t able to do anything further to try and solve the problem. I then rebooted again, and that’s when I found that when I logged in, that after a few seconds the screen goes black. I am able to move the cursor and use Ctrl-Alt-Delete to logout, lock, switch the user, put it in sleep mode, shut it down and reboot. Unfortunately there is no restore point to go back to before this all occurred. Please help!

    Have you tried booting into Safe mode and see if the screen and everything works correctly? If you can get there then we can try some troubleshooting options.
    1. Boot to Safe mode using one of the options in the following link

    Tried safe mode, but when going to login, I get “sihost.exe unknown hard error”. After clicking the start menu or use the windows key, the screen goes black again. I have no problems with internet connection on my iPad or iPhone.

    Are you able to access safe mode with command prompt?

    I was briefly able to to input the commands
    net localgroup Administrators /addnetworkservice and netlocalgroup Administratiors /addlocalservice
    . The commands were successfully completed. I then rebooted with no result.

    Once you are safe mode does the screen stay on or go black again? See if you can access safe mode again and copy and paste the following commands. Do you have a backup of your files if you need to reinstall?

    Step 1:
    1. syteminfo > 0 & notepad 0 ( this will open notepad, please copy and paste the contents to your reply.)
    2. rstrui ( this will open system restore, try to restore to a point before the problem occurred)

    Step 2:
    1. Sfc /Scannow
    2. Dism /Online /Cleanup-Image /RestoreHealth

    let me know if these run with any errors

    Okay, I did some research on this error and it seem to be an issue with an update that has affected several users.

    See if you can boot into,safe mode with networking then try rhe following options.

    Option 1:
    1. Press Windows logo key + R, type ms-settings in the Run box then select OK. This opens Settings menu
    2. In Settings, choose Update & security > WindowsUpdate , and then select Check for updates. Install any available updates and restart your PC


    Option 2:


    1. booting into safe mode with command prompt
    2. type net user administrator /active:yes, and then press Enter.
    3. exit and restart and try logging in with the default administrator account
    4. check for and install the latest updates.
    5. If this works then you may need to create a new user account and copy your current user to the new the new user profile created.

    Stays on until I try to click Start and then goes black, but I’m still able to see cursor. Like I told you previously, there are no restore points created to before this occurred. No backup of files in case I need to reinstall which is something I hope not to have to do. By the way, I’m replying to you from my iPad because of the situation with the PC.

    Option 1 isn’t working because trying to login after selecting option 5 to boot into safe mode with networking and then pressing windows key + r after I see icons on the screen, it just goes black again. I also got the same sihost error. I was able to login to admin account and waited for setup to complete. Once complete, screen went black again with curser still able to move. I then left it for 1/2 hr to see if the desktop would load, but screen went black.

    Okay, sorry I forgot you mentioned no restore points. Did you try option 1 above. Does it still go blank when you use the Windows key combination instead of clicking on Start?

    What happens if you boot directly into safe mode with command prompt. Are you able to enter any commands?
    If so try to do the following from command prompt:

    option 1:

    Type or copy and paste the commands below and press Enter after each one.

    Change the all c:/ commands to the correct Windows drive letter below. If you need help, copy and paste the following command:

    bcdedit |find "osdevice" (this will display the correct Windows drive letter)

    1. C:\
    2. cd c:\windows\system32\config\regback
    3. Dir (This will list the contents of regback, note the date and be sure that the contents are not empty. If it is empty then this will not work STOP and DO NOT proceed

    4. cd windows/system32/config
    5. md backup
    6. Copy *.* backup
    7. cd regback
    8. copy *.* ..
    9. Restart computer and test

    Option 2:

    1. Back up your files using using one of the following options:
    EaseUs todo backuphttps://www.easeus.com/backup-software/
