How to Fix a Black Screen on Boot in Windows 11

The Problem

Power lights and fans work, but the screen stays black—before Windows, after the logo, or at login with only a cursor. That is different from "second monitor not detected" when Windows is running fine on the laptop screen. For dual-monitor issues, use second monitor not detected instead.

Step 1: Fix no picture at all (not even BIOS)

Check power, input, and cable

  1. Monitor on the correct HDMI / DisplayPort input.
  2. Cable seated on the graphics card outputs if you have a dedicated GPU—not the motherboard ports (unless you have no GPU and use CPU graphics).
  3. Try another cable and port; test the monitor on another device if you can.

Hardware basics

If there is never a motherboard logo:

  1. Reseat RAM (one stick in the slot the manual recommends for single-channel test).
  2. Clear CMOS per the board manual.
  3. Listen for beep codes or check POST debug LEDs.

Step 2: Fix black screen after the Windows logo

Boot Safe Mode and undo the last change

Use enter Safe Mode in Windows 11—from Automatic Repair after three interrupted boots, or Shift + Restart from the sign-in screen if you can reach it.

In Safe Mode:

  1. Settings → Windows Update → Update history → Uninstall updates (remove the latest quality or driver update).
  2. Device Manager → Display adapters → uninstall the GPU driver → reboot.

Cursor on black, PC sounds "alive"

  1. Win + Ctrl + Shift + B to reset the graphics driver.
  2. Ctrl + Alt + Del → sign out, or type your password blind at login if you hear the startup sound.
  3. Once in: disable fast startup (Control Panel → Power Options → Choose what power buttons do → uncheck Turn on fast startup).

Recovery Options

From Automatic Repair → Advanced options:

  1. Startup Repair first.
  2. System Restore if you have a restore point from before the issue.
  3. Reset this PC → keep files: reinstall Windows without losing data.

Laptop Note

If HDMI to a TV works but the built-in panel does not, the lid cable or panel may be bad—software fixes will not help.
