The Problem

Power lights and fans run, but the screen stays black—before Windows loads, after the logo, or at the login screen with only a cursor. That is different from a second display not being detected while Windows runs normally; for that, use second monitor not detected.

First: Work Out Which Black Screen You Have

The three cases have completely different causes, and this one question saves hours.

| What you see | What it means | Go to | |---|---|---| | Nothing at all — no manufacturer logo, no BIOS | The PC is not producing video. Hardware or display path | Part A | | Logo appears, then black before sign-in | Windows starts and fails — usually the graphics driver | Part B | | Black with a movable mouse cursor | Windows is running; Explorer or the display output failed | Part C |

Test: press Num Lock and see whether the keyboard LED toggles. If it does, the machine is alive and you are in case 2 or 3.

Part A: No Picture At All, Not Even BIOS

Check the display path

  1. Confirm the monitor is on its correct HDMI / DisplayPort input—monitors do not always auto-switch.
  2. On a desktop with a graphics card, the cable must go into the card's ports at the rear, not the motherboard's. Motherboard ports are inactive on most systems with a discrete GPU.
  3. Swap the cable, then the port. Try the monitor on another device.

Basic hardware checks

If there is never a manufacturer logo or POST screen:

  1. Reseat the RAM. Power off, unplug, remove all sticks, and refit one in the slot the motherboard manual specifies for single-module operation. This alone fixes a large share of no-POST cases.
  2. Reseat the graphics card and its power connectors.
  3. Clear CMOS per the board manual—either the jumper or removing the coin cell for a minute with the power cable unplugged.
  4. Listen and look. Beep codes, the motherboard's debug LEDs (CPU / DRAM / VGA / BOOT), or a two-digit POST code tell you exactly which stage is failing.
  5. On a laptop, connect an external monitor via HDMI. If the external display works, the panel, its cable, or the backlight is the fault.

Get into Safe Mode

Force-shutdown at the logo three times to trigger the recovery environment, then Troubleshoot → Advanced options → Startup Settings → Restart → press 4. Full instructions: how to enter Safe Mode.

Undo whatever changed

In Safe Mode, in this order:

  1. Device Manager → Display adapters → right-click the GPU → Uninstall device, ticking Attempt to remove the driver. Restart. Windows boots with the basic display driver, which almost always produces a picture.
  2. Settings → Windows Update → Update history → Uninstall updates — remove the most recent quality update.
  3. Run System Restore (rstrui) to a point before the problem: create and use a system restore point.
  4. Reinstall the graphics driver cleanly once you have a picture: clean install GPU drivers with DDU.

Multi-monitor setups: Windows sometimes sends the desktop to a display that is off. Press Win + P blind and tap the down arrow then Enter to cycle modes.

Part C: Black Screen With a Cursor

  1. Press Win + Ctrl + Shift + B. This restarts the graphics driver; you should hear a short beep and the screen may recover immediately.
  2. Press Ctrl + Alt + Del. If the security screen appears, the problem is Explorer, not the display.
  3. From that screen open Task Manager → Run new task → type explorer.exe → OK.
  4. If that fixes it, the shell is failing at sign-in. Once you are in, run:
sfc /scannow

DISM /Online /Cleanup-Image /RestoreHealth

Details: repair Windows 11 with SFC and DISM.

  1. Then disable Fast Startup: Control Panel → Power Options → Choose what the power buttons do → Change settings that are currently unavailable → untick Turn on fast startup. A stale saved kernel image is a common cause of a repeating black-screen-at-login.

A corrupted user profile produces the same symptom—see fix "signed in with a temporary profile" and fix "User Profile Service failed the sign-in".

Recovery Options, In Order

From Automatic Repair → Advanced options:

  1. Startup Repair — one attempt.
  2. System Restore — if you have a restore point from before the problem.
  3. Uninstall Updates — quality update first, then feature update.
  4. Reset this PC → Keep my files: reinstall Windows without losing data.

What Not to Do

  • Don't keep force-powering off repeatedly once you have reached the recovery menu—each interrupted boot risks the update or filesystem state.
  • Don't buy a new graphics card before testing the monitor and cable on another machine.
  • Don't reinstall Windows first. Almost every case here is a driver or boot-configuration fault that a Safe Mode session resolves.

Laptop Note

If HDMI to a TV shows a picture but the built-in panel stays black, the fault is the panel, its backlight, or the lid cable—no software fix applies. Shine a torch at the screen at an angle: if you can faintly see the desktop, the panel works and the backlight or its inverter has failed.
