Black Screen With Cursor in Windows 11: Fixes Before and After Login

A black screen with a pointer you can move tells you more than it seems. The PC is on, Windows has loaded and the graphics driver is drawing at least the pointer. What’s missing is everything behind it: the sign-in screen, or, once you’ve signed in, the desktop and taskbar that Windows Explorer draws.

When it happens decides the fix. Before sign-in, suspect the display driver, the screen Windows is sending its picture to, or an update that hasn’t finished. After sign-in with only a pointer, the usual causes are explorer.exe not starting, a startup app or security tool getting in its way, a damaged user profile, or a replaced shell.

Two look-alikes need different fixes. A black screen with a blinking cursor (an underscore) before the Windows logo isn’t a pointer: Microsoft says it means the firmware can’t find a boot device. And with no pointer at all and a no-signal message, start with monitor says no signal instead.

Before or after sign-in? Find your row

Note when the screen goes black and what still responds.

Moves that work at any stage

The quick checks at the top of this page are safe at any stage and change nothing permanently. Two details matter:

• Windows + P matters most after a meeting or a dock change, when Windows can keep sending its picture to a TV, projector or monitor that’s now off or unplugged. On a laptop, unplug the dock and external cables, then try again.
• Force it off only as a last step. If nothing responds, hold the power button until the PC turns off; Microsoft suggests about 20 seconds. Unsaved work is lost, so give a PC that was installing updates time first.

Black screen after sign-in: restart Explorer, then find the cause

If you signed in and got only a pointer, Windows is running but its shell, explorer.exe, isn’t. Explorer draws the desktop and the taskbar, including the Start button, so without it the screen stays black.

Start it from Task Manager as in the quick checks above (on Windows 10, Run new task is under File). If Windows Explorer is already in the process list, it’s running but stuck; our File Explorer not responding guide covers restarting it.

If the desktop comes back, something still kept Explorer from starting. Restart once; if the black screen returns, work through these causes.

Check what crashed Explorer

While the desktop is up, select Run new task in Task Manager and run perfmon /rel to open Reliability Monitor. Select a red Windows Explorer entry marked Stopped working, then View technical details: a faulting module from a third-party app tells you what to update or uninstall. The File Explorer guide also shows how to turn shell add-ons off one by one.

A startup app or add-on

If no single app stands out, a clean boot tells you whether a startup app, service or security tool is to blame. In Task Manager, select Run new task, tick Create this task with administrative privileges and run msconfig. On the Services tab, check Hide all Microsoft services and select Disable all. On the Startup tab, select Open Task Manager, then disable each item under Startup apps, noting what you turned off. Select OK and restart.

If the desktop now loads normally, turn items back on a few at a time, restarting each time, until the black screen returns; the last batch holds the culprit. To undo it, choose Normal startup on the General tab, select Enable all on the Services tab and then Apply, and turn the startup apps you noted back on in Task Manager. Until you do, third-party antivirus, backup and sync tools may not run, so don’t stay in a clean boot longer than you need. On a company PC, ask whoever manages your security software first.

Only one account

Sign out from the Ctrl + Alt + Delete screen and sign in with another account. If that one reaches a normal desktop, the fault is in your profile: copy your files out and repair it with our user profile repair guide. If the PC has no other account, an administrator can create a test one: select Run new task with administrative privileges to open cmd, then run net user testlocal * /add, which asks for a new password. Delete it afterward with net user testlocal /delete, and on a company PC ask your IT admin before adding any local account.

Black screen before sign-in: Safe Mode, drivers and updates

If the sign-in screen never appears, start Windows in Safe Mode. It loads a basic display driver and skips startup apps, so it separates a driver problem from a deeper one.

On an encrypted PC, Startup Settings and some other recovery tools need the BitLocker recovery key. Look it up on another device first: aka.ms/myrecoverykey for a Microsoft account, aka.ms/aadrecoverykey for a work or school account, or ask your IT admin.

1. If Ctrl + Alt + Delete brings up a screen with a power icon, hold Shift while you select Power > Restart. That opens the Windows Recovery Environment (WinRE) without forcing the PC off.
2. If nothing responds, hold the power button for about 10 seconds to turn the PC off. Turn it on and, as soon as the logo or spinning dots appear, hold the button again. Do that twice; on the third start Windows should open WinRE. On the Automatic Repair screen, select Advanced options.
3. Choose Troubleshoot > Advanced options > Startup Settings > Restart, then press 5 or F5 for Safe Mode with Networking.

Have your account password ready, not just your PIN: fingerprint and face sign-in usually aren’t available in Safe Mode, and a PIN may not be either. Then:

• Safe Mode shows a normal desktop: the display driver or a startup app is the cause. If the trouble began after an update, open Device Manager, expand Display adapters, right-click the adapter, choose Properties and on the Driver tab select Roll Back Driver. If that’s grayed out, install the current graphics driver from the PC maker’s support site for your exact model. Then try the clean boot above.
• Safe Mode is black too: go back to WinRE. Uninstall Updates offers the latest quality update (the monthly one; pick it unless the trouble began right after a version upgrade) or the latest feature update. System Restore rolls system files and settings back to a restore point from before the problem, if System Protection was on and one exists. Neither touches your documents. A removed update comes back through Windows Update later, so it only buys time until a fixed version arrives.

In an office, if several PCs went black after the same update, check Microsoft’s Windows release health page for a known issue and pause that update for everyone in Intune or your update tool.

Fast Startup and unfinished updates

With Fast Startup on, Shut down saves the kernel and its loaded drivers to a hibernation file and loads them back at the next power-on, so a stuck driver can survive overnight. Restart doesn’t do this. To rule it out completely, turn it off:

1. Open Control Panel and set View by to Large icons.
2. Select Power Options > Choose what the power buttons do > Change settings that are currently unavailable.
3. Under Shutdown settings, clear Turn on fast startup and select Save changes.

Cold starts take a little longer afterward. If the option isn’t listed, hibernation is off on that PC and Fast Startup isn’t involved.

Big Windows updates finish some work at the first restart and sign-in, which on an older PC can look like a black screen with a pointer for a while. Keep a laptop on its charger and give it half an hour. If nothing changes, restart from the Ctrl + Alt + Delete screen; if the black screen returns every time, remove the update as described above.

When the Windows shell has been replaced

Windows decides what to run as your desktop from a registry value called Shell, normally explorer.exe. Kiosk setups such as Microsoft’s Shell Launcher (Enterprise and Education editions) change it on purpose; leftover kiosk or point-of-sale software and some malware change it without asking. Suspect this when every account gets a black screen or an unexpected app, Explorer starts fine by hand, and a clean boot changes nothing.

Warning: a wrong registry edit can stop Windows from starting or sign every account straight back out. Export each key before you change it and change only the value you’re fixing. On a company PC, leave this to your IT admin: a custom shell may be intentional and set by Intune or Group Policy.

1. In Task Manager, select Run new task, tick Create this task with administrative privileges and run regedit.
2. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and check that Shell reads exactly explorer.exe. A second program after a comma is a red flag; Eshell.exe or CustomShellHost.exe usually means Shell Launcher was set up on purpose.
3. In the same key, check that Userinit reads C:\Windows\system32\userinit.exe, with nothing after the comma. Userinit starts your shell at sign-in, and anything listed after it runs at every sign-in too.
4. Check HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon as well. A Shell value there applies only to the signed-in user, and on most PCs there isn’t one. If you typed another account’s password to open regedit, this key shows that account instead; on a standard account, check it in regedit opened without the administrative box.

If you find a program you don’t recognize, don’t just reset the value. Run a full scan with Microsoft Defender or your security software, then change the passwords used on that PC from a different device you trust, not from the affected PC. On a business PC, treat it as a security incident.

When it’s a startup or hardware problem

• Blinking underscore before the Windows logo. Windows hasn’t started, so the fixes above don’t apply. Remove USB drives, memory cards and discs, then restart. If it persists, check in the PC’s firmware setup that the Windows drive is first in the boot order and that boot mode wasn’t switched from UEFI to Legacy or CSM, which Dell notes leaves a UEFI-installed PC with no boot device. If the drive isn’t listed at all, it may have failed, so stop and get the data checked before trying repairs.
• No pointer at all on a laptop. With no lights it’s power; with the power light on, the screen or startup is failing before Windows draws anything. HP laptop won’t turn on and Dell laptop won’t turn on cover both cases.
• The pointer freezes as well, or the black screen comes with loud fans, clicking from the drive, or a PC that’s hot to the touch. Treat it as hardware and back up as soon as you can reach your files.
• Safe Mode, System Restore and removing updates all fail. Repairing or resetting Windows comes next, and a reset can remove apps and data, so copy your files off first or get help.

If you can reach a desktop at all, even by starting Explorer from Task Manager, this is a typical $59 remote fix: in a session you approve and can end at any time, a technician works through these checks to track down the driver, update or startup app behind it while you watch.

Common questions

Why is my screen black but I can still move the mouse?

Because Windows and the graphics driver are working; only the layer you expect to see is missing. Before sign-in, that’s usually the sign-in screen failing to draw or showing on another display. After sign-in, it’s usually Windows Explorer, the program that draws the desktop and taskbar, not starting. Restarting the graphics driver or starting Explorer from Task Manager tells you which.

Can a virus cause a black screen with a cursor?

It can. Some malware replaces the Windows shell so it runs at every sign-in instead of the desktop, or crashes Explorer. It’s far less common than a driver, update or startup app problem, though. If the Shell registry value names something you don’t recognize, or the black screen appeared along with pop-ups or strange accounts, run a full scan and treat the PC as compromised until it’s checked.

Will resetting Windows fix a black screen with a cursor?

Often, but it’s the most disruptive option and rarely needed. Choosing Keep my files saves your documents, yet Windows is reinstalled and every app you added is stripped out, so you’d spend hours setting things back up. Restarting Explorer, rolling back the display driver, a clean boot or removing the latest update fixes most cases. If you do reset, copy your files to another drive first.

Does a black screen with a cursor mean my graphics card is failing?

Usually not. A failing graphics card tends to show garbled colors, lines or artifacts, including on the manufacturer’s logo and in firmware setup, or no picture at all. A clean pointer on black means the card is drawing correctly and Windows isn’t giving it anything else to show, which points at software. Suspect hardware if the problem also appears before Windows starts.

Why do I only get a black screen when my laptop is docked?

Windows is probably sending the sign-in screen or desktop to a monitor on the dock that’s off, asleep or on the wrong input. Wake the monitors and check their inputs, press Windows + P to change the display mode, or undock, sign in, and dock again. If it happens every morning, update the dock’s firmware and the graphics driver from the laptop maker.

Why do I get a black screen with a cursor after sleep?

Usually the graphics driver or a docked monitor didn’t come back cleanly when the PC woke. Press Windows + Ctrl + Shift + B to restart the graphics driver, then Windows + P to resend the picture. If the pointer moves but there’s no taskbar, Explorer crashed: restart it from Task Manager. If it happens after most sleeps, install the current graphics driver and dock firmware from the PC or dock maker.
