Since the black screen happens at sign-in and a hard power-off temporarily clears it, use this order of troubleshooting:
- Try the display recovery shortcuts again in this sequence:
- Press Windows + P, then press P again and Enter to cycle display modes.
- Press Ctrl + Alt + Del. If the security screen appears, open Task Manager.
- In Task Manager, restart Windows Explorer. If it is not listed, select File > Run new task, type
explorer.exe, and press Enter.
- Check whether Windows is loading the correct shell.
- This issue can happen when sign-in completes but the desktop shell does not start.
- Open Registry Editor with Windows + R, type
regedit, and go to:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon - Verify the Shell value is
explorer.exe. - Warning: editing the registry can cause serious problems if done incorrectly. Back up the registry before making changes.
- Perform a clean boot.
- If the shell value is correct, perform a clean boot to identify whether a startup app or service is causing the black screen after sign-in.
- Boot into Safe Mode and check the display driver state.
- Force shutdown by holding the power button for about 10 seconds.
- Repeat this 2–3 times until Windows enters Recovery Mode.
- Go to Troubleshoot > Advanced Options > Startup Settings > Restart.
- Press F5 for Safe Mode with Networking.
- In Device Manager, expand Display adapters, right-click the GPU, and choose Update driver.
- If the problem started after a driver or Windows update, choose Roll back driver instead.
- If the issue began recently, use recovery options:
- In Recovery Mode, try Startup Repair.
- If available, try System Restore to a point before the issue started.
- If the problem began after an update, try uninstalling the latest update from Troubleshoot > Advanced Options.
- Check for broader system causes once the PC starts normally:
- Open Device Manager and look for devices marked with an exclamation point.
- Make sure the system drive has roughly 10% to 15% free space.
- Go to Start > Settings > Windows Update and install the latest updates.
If the system works normally only after a forced shutdown and this continues even after Safe Mode checks, clean boot, and recovery actions, the next supported path is System Restore or other Recovery options in Windows 11.
