Blank screen

Question

When I log in to my computer after lockscreen, then black screen shows cursor , cursor can move but when I try to open task manager with Ctrl +shift+esc. It gives no response

Answer 1

Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

Do this twice

On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt... etc.

Please try each option one at a time, then see if Windows will boot to a stable system.

1

If there is an option to uninstall the latest update, that may be the best option.

2

Go to Troubleshoot - Advanced Option - Startup Repair

See if Windows startup can repair itself

3

Go to Troubleshoot - Advanced Option - System Restore

Check to see if you have a restore point you can go back to

Answer 2

Try these steps in order:

1. Wake or reset the display

• Press Windows + Ctrl + Shift + B once.
• The screen should briefly flicker or a beep may be heard if the graphics driver resets.

2. Check display mode

• Press Windows + P.
• Press P again, then Enter to cycle display modes (PC screen only / Duplicate / Extend).
• Repeat this a few times in case Windows is sending output to a non‑existent display.

3. Force a restart

• Hold the power button for about 20 seconds until the PC turns off.
• Turn it back on and sign in again to see if the desktop appears normally.

4. Boot into Safe Mode If the black screen with cursor persists:

• Force shutdown by holding the power button for 10 seconds.
• Turn the PC back on and repeat the force shutdown 2–3 times until Windows Recovery Environment appears.
• Go to Troubleshoot > Advanced options > Startup Settings > Restart.
• Press F5 to choose Safe Mode with Networking.

5. Update or roll back the graphics driver (in Safe Mode)

• In Safe Mode, open Device Manager.
• Expand Display adapters.
• Right‑click the graphics adapter:
  • Choose Update driver and let Windows search for drivers, or
  • If the issue started after a recent driver update, choose Properties > Driver > Roll Back Driver.
• Restart normally and test.

6. Restart Windows Explorer (if Task Manager opens) If at any point Ctrl + Alt + Del works and allows opening Task Manager:

• Press Ctrl + Alt + Del and choose Task Manager.
• In Task Manager, find Windows Explorer, right‑click it, and select Restart.
• If Windows Explorer is missing, select File > Run new task, type explorer.exe, and press Enter.

7. Use System Restore (if problem started recently) If the issue began after an update or software install:

• Boot into Safe Mode or Recovery Mode as above.
• Go to Troubleshoot > Advanced options > System Restore.
• Choose a restore point from before the black‑screen issue started and complete the restore.

If none of these steps resolve the issue, the problem may be deeper (for example, corrupted system components or incompatible drivers) and a repair install or reset of Windows might be required.
