How do I fix my laptop from sticking in black screens cursor or locks?

1. Try a Windows Key Sequence to Wake the Screen.
2. Open Task Manager to Restart Windows Explorer.
3. Roll back the Display Adapter Driver.
4. Uninstall your Display Adapter Driver.
5. Perform a System Restore.

It sounds like your user profile may be corrupted. You could try CTRL+ALT+DEL and open task manager from the security prompt if it opens. In task manager click File -> Run New Task. Type Explorer.exe into the dialog box and hit OK, the desktop should launch.

If that doesn't work then I would try to get into safe mode from the log in screen:

• "Get to safe mode from the Windows sign-in screen:
• On the Windows sign-in screen, press and hold the Shift key while you select Power Circle with line Power icon > Restart.
• After your PC restarts to the Choose an option screen, select Troubleshoot > Advanced options > Startup Settings > Restart.
• After your PC restarts again, select the startup setting you want to use.

*

• When you're done, exit safe mode by restarting your PC. If that doesn't work:
• Press the Windows logo key Windows logo Start button + R.
• Type msconfig in the Open box and then select OK.
• Select the Boot tab.
• Under Book options, clear the Safe boot checkbox."
