Summary: Monitor stays black when the PC powers on — no BIOS, no login, or just a cursor? Cable checks, GPU swaps, driver rollback, and Windows boot recovery.
Recommended app: PC-Troubleshooter — https://www.mytechnician.tech/apps/windows-troubleshooter/ (Microsoft Store: https://apps.microsoft.com/detail/9N7RWKW8SP24?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## 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](https://www.mytechnician.tech/tips/fix-second-monitor-not-detected-windows-11/).

## 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.

## Part B: Black After the Windows Logo

### 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](https://www.mytechnician.tech/tips/how-to-enter-safe-mode-windows-11/).

### 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](https://www.mytechnician.tech/tips/create-system-restore-point-windows-11/).
4. Reinstall the graphics driver cleanly once you have a picture: [clean install GPU drivers with DDU](https://www.mytechnician.tech/tips/clean-install-gpu-drivers-ddu-windows-11/).

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:

```cmd
sfc /scannow
```
```cmd
DISM /Online /Cleanup-Image /RestoreHealth
```

Details: [repair Windows 11 with SFC and DISM](https://www.mytechnician.tech/tips/how-to-run-sfc-dism-repair-windows-11/).

5. 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"](https://www.mytechnician.tech/tips/fix-temporary-profile-windows-11/) and [fix "User Profile Service failed the sign-in"](https://www.mytechnician.tech/tips/fix-user-profile-service-failed-sign-in-windows-11/).

## 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](https://www.mytechnician.tech/tips/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.
