A Windows 11 black screen is usually caused by a display connection or projection setting, a graphics driver that has stopped responding, or Windows Explorer failing to load. Start by pressing Windows + Ctrl + Shift + B to reset the graphics driver, then check cables and press Windows + P. If that fails, the fixes below work through safe mode, driver rollback and Windows recovery tools in order.
| What you see | Most likely cause | Try first |
|---|---|---|
| Black screen with a mouse cursor after sign-in | Windows Explorer (the desktop shell) did not start | Ctrl + Alt + Del > Task Manager > run explorer.exe
|
| Black screen, no cursor, PC clearly running | Graphics driver hang or wrong display output | Windows + Ctrl + Shift + B, then Windows + P |
| Black screen after a driver or Windows update | New driver or update incompatible with your hardware | Safe mode, then roll back the driver or uninstall the update |
| Black screen before Windows loads | Monitor, cable, GPU or boot problem | Check connections, then Windows Recovery Environment |
Why is my Windows 11 screen black?
A black screen in Windows 11 means the PC is running but nothing usable is being drawn on the display. The most common causes are a loose or wrong display connection, Windows sending its picture to a different output, a graphics driver that has crashed or updated badly, or the Windows Explorer shell failing to start after sign-in.
Less often, a recent Windows update, a faulty startup app, or a hardware fault in the monitor or graphics card is to blame. Working through the fixes from simplest to most involved saves time, because the quick checks solve most cases.
Cause and effect: the GPU driver sits between Windows and your graphics hardware. When it stops responding, Windows itself may still be running fine, which is why you can often hear sounds or see drive activity while the screen stays dark.
What is the difference between a black screen with a cursor and without one?
A black screen with a visible mouse cursor usually means the graphics driver works but the Windows Explorer shell, which draws the desktop and taskbar, has not loaded. A black screen with no cursor points more towards a display output, cable or graphics driver problem, because Windows is not drawing anything at all.
This distinction matters because the fixes differ. With a cursor, focus on Explorer, startup apps and your user profile. Without one, focus on connections, projection mode and the graphics driver.
What we commonly see: a cursor-only black screen straight after sign-in is often caused by a third-party app that loads at startup and hangs Explorer. A clean boot or safe mode quickly confirms this.
How do I wake up a black screen in Windows 11?
Press Windows + Ctrl + Shift + B together. This keyboard shortcut restarts the graphics driver without closing your apps, and you will usually hear a beep or see the screen flicker if it worked. It is the fastest, safest first step for a black screen with or without a cursor.
If nothing happens, try these quick checks in order:
- Make sure a laptop is charged or plugged in and that any external monitor is switched on and set to the correct input source.
- Press Windows + P, then P again and Enter. Repeat a few times to cycle through PC screen only, Duplicate, Extend and Second screen only, pausing a few seconds each time.
- Reseat the display cable (HDMI, DisplayPort or USB-C) at both ends, or try a different cable, port or monitor.
- On a desktop with a separate graphics card, connect the monitor to the card's ports, not the motherboard's.
- Unplug non-essential USB devices such as docks, hubs and external drives, then restart.
Microsoft's own blank screen troubleshooting guide recommends the same order: connections and shortcuts first, then deeper fixes.
How do I fix a black screen with a cursor?
Press Ctrl + Alt + Del and open Task Manager. If Windows Explorer appears in the list, right-click it and choose Restart. If it is missing, select Run new task, type explorer.exe and press Enter. This reloads the desktop and taskbar in most cases.
- Press Ctrl + Alt + Del, then select Task Manager. You can also try Ctrl + Shift + Esc.
- Select More details if Task Manager opens in its compact view.
- Find Windows Explorer under Processes, right-click it and choose Restart.
- If it is not listed, select Run new task, type
explorer.exeand select OK.
If the desktop returns but the problem comes back after every restart, open the Startup apps page in Task Manager and disable recently added items one at a time. Restart after each change to see which app is responsible.
Advanced nuance: if Task Manager itself will not appear, sign out from the Ctrl + Alt + Del screen and sign in with another administrator account. If the second account works normally, the issue is in your user profile rather than Windows itself.
How do I boot into safe mode from a black screen?
Force Windows into the Windows Recovery Environment (WinRE) by interrupting startup: hold the power button for about 10 seconds to switch off, turn it on, and repeat as Windows starts loading. After two or three interruptions, Windows shows Automatic Repair, from which you can reach safe mode.
- Interrupt startup two or three times until you see Preparing Automatic Repair, then select Advanced options.
- Choose Troubleshoot > Advanced options > Startup Settings > Restart.
- When the list appears, press F5 for Safe Mode with Networking (or F4 for basic safe mode).
Safe mode loads Windows with a basic display driver and only essential services. If the screen works there, the cause is almost certainly a driver, startup app or service rather than your hardware.
If your drive is protected by BitLocker or Device Encryption, Windows may ask for your recovery key before showing these options. Have it ready from your Microsoft account before you start.
How do I roll back or reinstall the graphics driver?
In safe mode, open Device Manager, expand Display adapters, right-click your graphics card and choose Properties > Driver > Roll Back Driver. If rollback is greyed out, choose Uninstall device instead, restart, and let Windows install a basic driver before you add the latest one from your PC or GPU maker.
- Right-click Start and select Device Manager.
- Expand Display adapters.
- Right-click your graphics adapter and select Properties, then the Driver tab.
- Select Roll Back Driver if available, choose a reason and confirm.
- If rollback is unavailable, return to the device list, right-click the adapter, select Uninstall device and restart.
Get replacement drivers only from Windows Update, your PC manufacturer's support site, or the graphics chip maker (Intel, AMD or NVIDIA). Avoid third-party "driver updater" tools, which can install the wrong version and make the problem worse.
Can Fast Startup or a Windows update cause a black screen?
Yes. Fast Startup saves part of Windows to disk at shutdown and reloads it on the next boot, which can carry a stuck driver state forward. A newly installed Windows update can also clash with an older driver. Disabling Fast Startup or uninstalling the latest update often fixes black screens that started suddenly.
To turn off Fast Startup:
- Open Control Panel > Hardware and Sound > Power Options.
- Select Choose what the power buttons do.
- Select Change settings that are currently unavailable.
- Clear Turn on fast startup (recommended) and select Save changes.
To remove a problem update, go to Settings > Windows Update > Update history > Uninstall updates. If you cannot reach the desktop, use Troubleshoot > Advanced options > Uninstall Updates in WinRE instead. A full restart, rather than shut down and power on, also bypasses Fast Startup for one boot.
What if none of these fixes work?
Use the Windows Recovery Environment's repair tools. Run Startup Repair first, then System Restore to roll back to a restore point from before the problem. If neither works, Reset this PC reinstalls Windows while letting you keep personal files. Persistent black screens before Windows loads point towards a hardware fault.
All of these tools live under Troubleshoot > Advanced options in WinRE, which Microsoft describes in its Windows Recovery Environment guide. Back up anything important first if you can reach it from safe mode.
If you reset or reinstall, a properly licensed copy of Windows 11 reactivates automatically on the same hardware through its digital licence. If you ever need to reinstall from scratch, our guides for Windows 11 Pro and Windows 11 Home cover installation and activation. If a replaced graphics card or motherboard leaves Windows unactivated afterwards, see our fix for activation error 0x803FA067.
What we commonly see: when the screen stays black even on the manufacturer's logo and BIOS screens, Windows is not the culprit. Test with another monitor and cable; if that fails too, the graphics card or display needs a hardware check.
Frequently asked questions
What does Windows + Ctrl + Shift + B do?
It restarts the graphics driver in Windows 11 without closing your open apps or losing unsaved work. Windows briefly blanks the screen and usually plays a short beep. It is a safe first step whenever the display freezes, goes black or flickers, and it works on desktops and laptops alike.
Why does my screen go black after installing a graphics driver?
The new driver may be incompatible with your hardware, your Windows version, or a laptop maker's customised graphics setup. Boot into safe mode, roll the driver back in Device Manager, then install the version offered by your PC manufacturer's support site, which is tested for your specific model.
Will resetting my PC fix a black screen?
Reset this PC often fixes black screens caused by corrupted system files, bad drivers or problem software, because it reinstalls Windows. It will not fix faulty hardware such as a failing graphics card or cable. Try Startup Repair, driver rollback and System Restore first, as they are less disruptive.
Do I need my product key after resetting Windows 11?
Usually not. If Windows 11 was activated before, it reactivates automatically after a reset on the same hardware using its digital licence. If it was never activated, you will need a genuine key such as a Windows 11 Home or Windows 11 Pro licence.
Can a black screen be caused by a virus?
It is possible but uncommon. Malware can interfere with Windows Explorer or startup, producing a cursor-only black screen. If safe mode works, run a full scan with Microsoft Defender from there. Driver, display and update problems are far more frequent causes, so check those first.
