How to Fix a Windows Black Screen | Boot, Login, and Post-Update Cases

"The power is on but the screen is completely black." "After logging in, the desktop never appears — just a mouse cursor." "After a Windows Update, the screen went black and won't respond." Unlike a Blue Screen of Death, a Windows black screen gives you no error code, which makes identifying the cause the first real challenge. This guide covers Windows 11 (through 24H2) and Windows 10, sorts the symptoms into distinct patterns, and walks through every fix in order — from cables and monitors through drivers, graphics cards, startup programs, and OS file corruption. There are many options to try before you reach for the power button, so work through them from the top.

Identify your pattern: types of black screen and their causes

"Black screen" covers very different situations depending on exactly when the screen goes dark. Think back to what you saw after pressing the power button and match your experience to one of the patterns below.

Black from the moment you press the power button (no BIOS screen)

The manufacturer's logo never appears and nothing shows up at all. This is a pre-OS problem — the issue lies in the hardware or display connection before Windows even starts loading. If the power LED and fans come on, the system is getting power, so look at the cable, monitor, and graphics card. If even the BIOS screen never appears or you keep dropping into Automatic Repair, see How to Fix a Windows PC That Won't Boot | BIOS, Recovery Environment, and Safe Mode Steps as well.

Stalls after the Windows logo

The Windows startup animation plays, then the desktop never appears. The usual culprits are corrupted system files, a driver conflict, or a recently installed program. Booting into Safe Mode is the standard first diagnostic step.

You sign in normally, then the screen goes black with only the mouse cursor moving. This almost always means explorer.exe has crashed. Press Ctrl+Alt+Delete to reach Task Manager and restart the process — this fixes the problem in the majority of cases.

Black screen after a Windows Update

If the black screen appeared immediately after an update, suspect an update failure or a driver compatibility issue. Graphics driver and cumulative updates are frequent offenders; uninstalling the relevant update usually resolves it.

Quick-reference table by symptom

Symptom	Primary cause	First thing to try
No BIOS screen at all	Cable, monitor, or GPU	Reseat cable / try different port
Stalls after Windows logo	Driver or OS corruption	Boot into Safe Mode
Cursor only after login	explorer.exe crashed	Ctrl+Alt+Delete → Task Manager
Happens after an update	Update bug	Uninstall the update from Safe Mode
Happens after waking from sleep	GPU driver	Win+Ctrl+Shift+B

Check the display and cables first

Reseat the HDMI or DisplayPort cable

The most frequently overlooked cause is a loose cable connection. On a desktop, unplug both ends of the video cable — the port on the PC and the port on the monitor — and push each one firmly back in. DisplayPort connectors have a small locking latch that must click into place; it's easy to end up with a half-inserted connection.

If possible, swap in a different cable or try a different port. HDMI 2.1 and DisplayPort 1.4 cables can develop internal breaks that aren't visible, and swapping the cable is enough to fix the issue in many cases.

Switch the monitor's input source

Monitors with multiple inputs (HDMI 1, HDMI 2, DisplayPort, VGA, and so on) will show a black screen if the selected input doesn't match where your PC is plugged in. Open the monitor's on-screen menu and manually select the correct input. The auto-detect feature can misfire on some models.

The second-monitor trap

If you've ever connected an external monitor to a laptop, Windows may have saved "Second screen only" as the display mode. With nothing connected, the built-in screen goes black. Press Win+P and select "PC screen only" to bring the laptop display back (more detail below).

Wake the display when the OS is still running

Win+Ctrl+Shift+B — restart the graphics driver

If the OS appears to be running (the PC makes sounds, speakers work) but the screen is black, try restarting the graphics driver.

Press Win + Ctrl + Shift + B simultaneously
After about a second, the screen flashes and you'll hear a short beep
If the display comes back, the driver successfully restarted — your open apps are untouched

This shortcut is built into Windows and is the go-to fix for black screen after waking from sleep.

Win+P — switch the projection mode

This shortcut cycles through display output modes (PC only, Duplicate, Extend, Second screen only). Even on a black screen, the keyboard may still be accepted, so try it blind.

Press Win + P
Press the ↑ key to select "PC screen only" (it's at the top of the list)
Press Enter to confirm

On a laptop that was stuck in "Second screen only," this alone brings the screen back.

Ctrl+Alt+Delete — check if the OS is alive

Pressing Ctrl+Alt+Delete brings up the security screen (blue background). If that screen appears, the OS is running — a good sign for recovery. From there you can choose "Restart" via the power icon in the lower-right, or open Task Manager to kill a stuck process.

Black screen after login: restart explorer.exe

Restart via Task Manager

When the desktop and taskbar don't appear after signing in, explorer.exe (Windows Explorer) has likely crashed.

Press Ctrl + Shift + Esc to open Task Manager
Click File in the upper-left → "Run new task"
Type explorer.exe and click OK
The desktop and taskbar should reappear

If explorer.exe is already listed in the Processes tab, right-click it and choose "End task" first, then run the new task as above. If Task Manager itself won't open, reach it via Ctrl+Alt+Delete → Task Manager.

Suspect a startup program

If you need to restart explorer.exe every time you log in, one of your startup apps may be hijacking the display pipeline. Open the Startup Apps tab in Task Manager and disable recently installed apps, legacy desktop tools, or overlay-type programs (screen recorders, chat apps with overlay features) one at a time to identify the culprit. For a full walkthrough of startup management, see Windows 11 Startup Settings | Add, Remove, and Speed Up Boot.

Boot into Safe Mode to isolate the cause

Force three shutdowns in a row to trigger Automatic Repair

If you can't even reach the sign-in screen, use Safe Mode to diagnose the issue. Forcing the power off three times in a row during the Windows boot process causes Windows to enter Automatic Repair on the fourth attempt.

While the Windows logo is on screen, press and hold the power button to force a shutdown
Repeat this three times
On the fourth boot, you'll see "Preparing Automatic Repair"
Choose Advanced options → Troubleshoot → Advanced options → Startup Settings → Restart
After the restart, press F5 to boot into Safe Mode with Networking

For more ways to reach Safe Mode, see How to Boot Windows in Safe Mode | Shift+Restart, msconfig, and Command-Line Methods.

Reinstall the graphics driver from Safe Mode

Once you're in Safe Mode, use the display result to interpret the cause:

Display works in Safe Mode: The problem is a driver or background program loaded in normal mode.
Still black in Safe Mode: More likely a hardware or BIOS/UEFI issue.

From Safe Mode, open Device Manager → Display Adapters, right-click the GPU, and choose "Uninstall device" (check "Delete the driver software for this device"). Restart; Windows loads a generic driver. Then download and install the latest driver from the GPU manufacturer's website.

Update or roll back the graphics driver

Update to the latest driver

NVIDIA, AMD, and Intel frequently include black-screen bug fixes in driver updates.

NVIDIA: Use GeForce Experience or the official website to get the latest Game Ready or Studio Driver
AMD: Use Radeon Software or the official AMD website
Intel: Use Intel Driver & Support Assistant or the official Intel website

Driver updates also appear under Settings → Windows Update → Advanced options → Optional updates — check there too.

Roll back to the previous version

If the black screen started after a driver update, rolling back is the most direct fix. Open Device Manager, right-click the GPU, choose Properties → Driver tab → "Roll Back Driver." If the button is greyed out, the previous version is no longer saved on the system.

Clean uninstall with DDU

If updating and rolling back haven't resolved the issue, use DDU (Display Driver Uninstaller) for a complete removal.

Boot into Safe Mode
Run DDU (free) and choose "Clean and Restart"
After the restart, download a fresh copy of the driver from the GPU manufacturer and install it

DDU removes residual registry entries and cached files that a normal uninstall leaves behind, making it significantly more effective for persistent driver problems.

Isolate startup apps and services with a clean boot

If the display works in Safe Mode but not in normal mode, a background app is causing the conflict. Use a clean boot to narrow it down.

Press Win+R, type msconfig, and press Enter
On the Services tab, check "Hide all Microsoft services" and disable everything that remains
On the Startup tab, click "Open Task Manager" and disable all startup entries
Restart and check whether the black screen is gone in normal mode

Once it's resolved, re-enable services and startup items in halves, restarting each time, until you identify the offender. Screen-capture overlays, old PC utility software, and security tools are the usual suspects.

Repair system files with SFC and DISM

After an abnormal shutdown or a failed Windows Update, system files can become corrupted. Open an administrator terminal from Safe Mode and run the following commands in order:

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

Run DISM first to repair the Windows image, then SFC to repair protected system files. Allow 20–40 minutes total. For more on using these tools, see How to Fix the Windows Blue Screen of Death | Stop Codes and Recovery Steps.

Uninstall a problematic Windows Update

If the black screen started after a specific monthly cumulative update, that update is likely the culprit. Uninstall it from Safe Mode:

Go to Settings → Windows Update → Update history
Scroll down to "Uninstall updates"
Select the most recently installed update and click Uninstall
Restart and check whether the black screen is gone

After rolling back, Windows Update may automatically re-download the same update. Use "Pause updates" temporarily until Microsoft releases a fix. For broader Windows Update troubleshooting, see How to Fix a Failed Windows Update | Free Up Space, Run the Troubleshooter, and Manual Install.

Suspect a hardware cause

Reseat the graphics card

On a desktop that shows nothing from the very first power-on, a loose graphics card is a common culprit. Fully power down the PC, unplug the power cord, open the side panel, remove the GPU, blow any dust from the PCIe slot, and firmly reseat the card. Also check that the auxiliary power connectors (6+2-pin or 8-pin) are fully inserted.

Reseat the RAM

A loose RAM stick can also prevent any display output. If your motherboard has two or more sticks, try booting with one stick at a time in different slots to isolate a faulty module.

Clear the CMOS to reset BIOS settings

If a BIOS change (overclocking, enabling XMP, changing display output) is what triggered the black screen, a CMOS clear resets the BIOS to factory defaults. Remove the motherboard's CMOS battery for about 10 minutes, or use the CMOS clear jumper if your board has one.

Last resorts

If nothing above has worked, the final options are:

System Restore: From the Automatic Repair menu, choose Advanced options → System Restore, and select a restore point from before the black screen appeared.
Reset this PC: Choose "Keep my files" to preserve your personal folders; apps, settings, and drivers will all need to be reinstalled.
Clean install: Boot from a Windows installation USB created on another PC and perform a fresh install.

Before resetting, back up your data to an external drive and confirm your Microsoft account credentials and any license keys you'll need after reinstalling.

Summary: fix order checklist

Here's the recommended sequence for tackling a Windows black screen.

Identify the symptom pattern (at power-on / after Windows logo / after login / after update)
Check the cable, monitor input source, and use Win+P to verify the display target
Try Win+Ctrl+Shift+B to restart the graphics driver
If the login screen is visible but the desktop isn't, use Ctrl+Alt+Delete → Task Manager → run explorer.exe
If you can't progress further, boot into Safe Mode
Update, roll back, or clean-uninstall the graphics driver with DDU
Run a clean boot to check for interference from background apps
Run DISM and SFC to repair system files
If the issue started after an update, uninstall that update
Check the hardware — GPU, RAM, and BIOS settings
As a last resort, System Restore or reset the PC

Most black screen cases resolve somewhere between steps 3 and 5. Before you hold the power button, try the keyboard shortcuts — there's a good chance they'll bring the screen back immediately.
