Your screen is completely black. Maybe there's a cursor, maybe there's nothing at all. Windows was loading — or you just woke it from sleep — and now you're staring into a void. This is the Black Screen of Death, and it affects millions of Windows 10 and 11 users every year, often after a login, a Windows Update, or waking from sleep.
The good news: it is almost never a sign of serious hardware failure. In the vast majority of cases it is caused by a crashed Windows Explorer process, a display driver conflict, or a Fast Startup bug — all of which are fixable in minutes without touching a single hardware component. This guide walks you through all 9 fixes in order from fastest to most thorough.
What is the Black Screen of Death & what do you do first?
The Black Screen of Death (BSOD) in Windows 10/11 is a completely black display — sometimes with a visible mouse cursor — that appears after login, after a Windows update, or when waking from sleep. It is not the same as the Blue Screen of Death. The most common causes are: a crashed Windows Explorer process, a display driver conflict, a Fast Startup bug, or a bad Windows Update.
First thing to try: Press Ctrl + Alt + Delete → click Task Manager → File → Run new task → type explorer.exe → OK. This restarts the Windows shell and fixes the black screen in roughly 70% of cases instantly.
Black Screen vs. Blue Screen — They Are Not the Same
Before doing anything, confirm which type of screen you have. Many users confuse them, and the fixes are completely different.
| Black Screen of Death | Blue Screen of Death (BSOD) | |
|---|---|---|
| What you see | Completely black display, sometimes with a mouse cursor visible | Blue background with sad face :( and a stop code (e.g. IRQL_NOT_LESS_OR_EQUAL) |
| When it happens | After login, after waking from sleep, after a Windows Update | Anytime — often during heavy use or immediately after a driver change |
| Primary cause | Windows Explorer crash, display driver failure, Fast Startup conflict | Kernel driver error, defective RAM, failing hard drive, hardware fault |
| Hardware involved? | Rarely — mostly software | Frequently — RAM, drive, or GPU hardware issues are common |
| First fix to try | Ctrl+Alt+Delete → Task Manager → run explorer.exe | Boot to Safe Mode and roll back drivers |
If your screen is black with a cursor and Windows was running before: you are dealing with a black screen. Continue reading. If you see a blue background with text and a QR code: see our separate guide on fixing the Blue Screen of Death on Windows 11.
What Causes the Black Screen of Death?
1. Windows Explorer Has Crashed
Windows Explorer (explorer.exe) is not just a file manager — it is the entire Windows shell. The taskbar, desktop icons, Start menu, and all on-screen UI elements are rendered by Explorer. When Explorer crashes, all of that disappears and you get a black screen. Your mouse cursor is often still visible because the cursor is rendered at a lower level than Explorer. This is the single most common cause of the black screen, and it fixes instantly by relaunching Explorer from Task Manager.
2. Display Driver Crash or Incompatibility
After a Windows Update or a GPU driver update, the new driver may be incompatible with your monitor or graphics card model. The driver initializes partially, then fails — and the display goes black. You may hear login sounds (the Windows chime) but see nothing. This is especially common with NVIDIA and AMD GPU drivers installed via Windows Update rather than directly from the manufacturer's website.
3. Fast Startup Conflict
Windows 10 and 11 use a feature called Fast Startup (also called Hybrid Boot) that saves a snapshot of the kernel state to a file (hiberfil.sys) when you shut down. On the next startup, Windows loads from this snapshot instead of doing a full boot. If the snapshot is corrupted — by a driver update, a forced shutdown, or a hardware change — Windows can get stuck with a black screen because it's trying to restore a broken state. Disabling Fast Startup forces a clean full boot every time and eliminates this entire category of black screens.
4. Bad Windows Update
Microsoft's cumulative updates occasionally introduce driver conflicts or shell bugs that cause a black screen on affected hardware configurations. This is most common in the days immediately following a major Windows Update — the problem is usually patched in the next update, but in the meantime you can uninstall the problematic update from Safe Mode.
5. Second Monitor or Display Cable Issue
Frequently overlooked: if you have two monitors and Windows is sending the output to the wrong one, or if a video cable is loose or damaged, you will see a black screen even though Windows is running perfectly. This is not a software bug at all — it is a physical connection issue that takes 30 seconds to check.
6. Background Application Conflict on Login
Some third-party startup applications (antivirus software, system utilities, screen management tools) can interfere with the Windows shell during login and cause a temporary or permanent black screen. This is distinguishable from an Explorer crash because Ctrl+Alt+Delete may not even appear, or may appear with a black background.
Is your PC making sounds but the screen is black?
If you can hear Windows starting — the login sound, notification sounds, or application audio — the operating system is running normally. The black screen is a display output problem, not a system crash. This narrows the cause to: display driver, second monitor/cable, or Windows Explorer. Start with Method 1 and Method 6 immediately.
9 Fixes for the Black Screen of Death — In Order
Work through these methods in order. Each one takes only a few minutes to try before moving to the next.
Restart Windows Explorer via Task Manager Fixes ~70% of cases
Press Ctrl + Alt + Delete. If the menu appears, click Task Manager. In Task Manager, click File → Run new task. Type explorer.exe and press Enter. The Windows shell will restart and your desktop should reappear within seconds.
If explorer.exe is already listed in the Processes tab: right-click it → End task, then use File → Run new task to relaunch it. Alternatively, in Task Manager go to File → Run new task, type explorer.exe and check "Create this task with administrative privileges."
If Ctrl+Alt+Delete does not bring up the menu at all: hold the power button to force shut down, then restart. After restart, immediately try the same method.
Disable Fast Startup Prevents recurring black screens
If the black screen happens every time you start your PC (or comes back after a restart), Fast Startup is almost certainly the cause. To disable it:
Open Control Panel (search for it in the Start menu) → Hardware and Sound → Power Options → Choose what the power buttons do (left sidebar) → click Change settings that are currently unavailable → uncheck Turn on fast startup (recommended) → click Save changes.
Fully shut down your PC (not restart — shut down), then power it back on. With Fast Startup disabled, Windows performs a complete clean boot every time, eliminating the corrupted hibernation snapshot problem.
Boot into Safe Mode and Uninstall Recent Driver or Update Essential if screen is always black
Safe Mode loads Windows with only essential Microsoft drivers — no third-party drivers, no startup apps. If Windows works in Safe Mode but shows a black screen normally, a third-party driver or recently installed update is the cause.
To enter Safe Mode: hold Shift and click Restart from the login screen or Start menu → Troubleshoot → Advanced options → Startup Settings → Restart → press F5 (Safe Mode with Networking).
If Windows won't get past the black screen to reach the login screen at all: force shut down by holding the power button 3 times in a row during startup. On the 4th boot, Windows automatically enters the Recovery Environment (WinRE), where you can navigate to Troubleshoot → Advanced options → Startup Settings.
Once in Safe Mode, go to Settings → Windows Update → Update history → Uninstall updates and remove the most recent cumulative update. Or open Device Manager and roll back any recently updated drivers.
Roll Back or Reinstall the Display Driver Critical for GPU-related black screens
The display driver is the most common hardware driver to cause a black screen. In Safe Mode (or if you can access Device Manager normally via Ctrl+Alt+Delete → Task Manager → File → Run new task → devmgmt.msc):
Expand Display adapters → right-click your GPU → Properties → Driver tab → Roll Back Driver. If Roll Back is greyed out (no previous version stored), choose Uninstall device and check the box to delete the driver software. Restart — Windows will install a basic generic driver that almost always works without a black screen. You can then download the correct driver from the manufacturer's website directly: nvidia.com, amd.com, or intel.com.
For NVIDIA specifically: use DDU (Display Driver Uninstaller) in Safe Mode for a completely clean removal. Download it from guru3d.com, run it in Safe Mode, choose "Clean and restart," then install the latest driver from nvidia.com directly.
Run Startup Repair from the Recovery Environment For startup-only black screens
If the black screen appears during the startup sequence — before or immediately after the Windows logo — Startup Repair can automatically detect and fix boot-related problems without any manual steps.
Access it by: holding Shift + Restart from the login screen, or by force-shutting down 3 times to trigger automatic WinRE. Navigate to Troubleshoot → Advanced options → Startup Repair. Windows scans for boot configuration problems and attempts to repair them automatically. The process takes 5–15 minutes. Restart when it finishes.
If you have a Windows installation USB drive: boot from it, choose your language, then click Repair your computer (bottom-left) → Troubleshoot → Startup Repair. This is the most powerful version of Startup Repair as it uses fresh repair files.
Check Second Monitor and Display Cable Connection Often overlooked — takes 30 seconds
This fix is embarrassingly simple but resolves more cases than you'd expect. If you have two monitors: unplug the cable from the second monitor and see if the first one lights up. Windows may be sending output to a monitor that is off, disconnected at the power end, or set to the wrong input.
Press Windows key + P (even on a black screen — Windows processes keyboard shortcuts without needing a visible display). This cycles through display modes: PC screen only → Duplicate → Extend → Second screen only. Press it a few times and wait 2 seconds after each press to see if the display comes back.
Also physically check the video cable: unplug it from both the PC and the monitor, reseat it firmly, and try a different cable if one is available. DisplayPort cables in particular can cause intermittent black screen issues when not fully seated.
Disable Wake-on-LAN and Hybrid Sleep For black screens after sleep/wake
If the black screen only appears when waking from sleep (the PC wakes, you hear sounds, but the screen stays black), the issue is with how Windows manages power transitions. Two settings to change:
Disable Hybrid Sleep: Control Panel → Power Options → Change plan settings → Change advanced power settings → expand Sleep → expand Allow hybrid sleep → set to Off for both On battery and Plugged in.
Disable Wake-on-LAN: Open Device Manager → expand Network Adapters → right-click your network adapter → Properties → Power Management tab → uncheck Allow this device to wake the computer.
Also try: when the screen is black after waking, press Ctrl + Alt + Delete and then Escape. Some display drivers fail to re-initialize after sleep and this key combination nudges Windows to refresh the display output.
Run sfc /scannow and DISM For persistent cases with corrupted files
If previous methods haven't resolved the issue, corrupted Windows system files may be causing Explorer or the display subsystem to fail at startup. Boot into Safe Mode (Method 3), then open Command Prompt as Administrator: press Win + X → Terminal (Admin).
Run SFC first: sfc /scannow — this scans all protected Windows files and replaces any corrupted ones from a cached copy. Takes 10–20 minutes. Do not close the window.
After SFC completes, run DISM to repair the Windows image itself:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
DISM needs an internet connection for RestoreHealth (it downloads replacement files from Windows Update). After it finishes, run sfc /scannow once more, then restart normally.
Perform a System Restore to Before the Black Screen Rolls back to a known working state
If you know roughly when the black screen started (after an update, after installing software), System Restore can roll Windows back to a point before the problem began — without affecting your personal files.
Access System Restore from the Recovery Environment: Troubleshoot → Advanced options → System Restore. Choose a restore point dated before the black screen started. The process takes 15–30 minutes and reverts driver versions, Windows updates, and registry settings to that earlier state.
If System Restore is not available in WinRE, it means System Restore was disabled on your PC (it is sometimes turned off by manufacturers to save disk space). In that case, your next option is Settings → System → Recovery → Reset this PC → Keep my files, which reinstalls Windows while preserving personal documents and photos.
Still black after all 9 methods? Try a clean Windows Reset.
If none of the above methods resolved the black screen, it is time for a Windows Reset. Go to Settings → System → Recovery → Reset this PC and choose Keep my files. This reinstalls Windows from scratch while preserving your personal documents, photos, and desktop files. Apps will need to be reinstalled. This resolves virtually 100% of software-caused black screens. If the black screen persists even after a full reset, the problem is hardware — almost always a failing GPU or a monitor issue — requiring professional diagnosis.
Black Screen Scenarios — Which Fix Applies to You?
| When does the black screen occur? | Most likely cause | Start with |
|---|---|---|
| After logging in — cursor visible, desktop never loads | Windows Explorer crash | Method 1 |
| Every time at startup — not just once | Fast Startup corrupted snapshot | Method 2 |
| Started right after a Windows Update | Bad update or driver conflict | Method 3 + uninstall update |
| After waking from sleep or hibernation | Hybrid sleep or display driver wake issue | Method 7, then Method 4 |
| After installing a new GPU or GPU driver | Display driver incompatibility | Method 4 |
| Black from the very start — before Windows logo | Cable, monitor input, or boot corruption | Method 6, then Method 5 |
| Second monitor connected recently | Wrong display output | Method 6 (Win+P) |

When Is It Actually a Hardware Problem?
The black screen is usually software. However, there are clear signs that point to a genuine hardware fault:
- The monitor displays "No Signal" even when the PC is clearly running (fans spinning, keyboard lighting on) — the GPU is not outputting a signal at all
- Black screen on multiple monitors with multiple cables — rules out cable and monitor issues
- Black screen persists after a full Windows Reset — only hardware can cause this
- The PC doesn't POST — no BIOS logo, no beep codes, just black — the motherboard or GPU may be faulty
- Black screen with artifacts or flickering just before it goes dark — suggests a failing GPU VRAM or display output circuit
If you see any of these signs, software fixes will not help. The next step is physical hardware testing: try a different GPU if you have one, test with the integrated graphics (Intel/AMD CPU graphics), or bring the PC to a technician for component-level diagnosis.
How to Prevent the Black Screen From Coming Back
- Keep Fast Startup disabled (Method 2) — it causes far more problems than it solves on most PCs
- Update GPU drivers manually — do not let Windows Update manage GPU drivers. Get them directly from nvidia.com or amd.com
- Pause Windows Updates for 1–2 weeks after major releases (Settings → Windows Update → Pause updates) — let others discover compatibility bugs first
- Enable System Restore — gives you a quick rollback point if a new update causes problems (Settings → search "Create a restore point")
- Check video cables every few months — DisplayPort and HDMI cables can develop micro-fractures that cause intermittent black screen issues
- Keep drivers and BIOS updated through official channels — outdated firmware can also trigger display conflicts
Frequently Asked Questions
What causes the Black Screen of Death on Windows?
The most common causes are a crashed Windows Explorer process (the entire Windows UI disappears, leaving only a black screen), a display driver crash or incompatibility after a Windows Update, the Fast Startup feature loading a corrupted hibernation snapshot, or a conflict with a recently installed application or driver. Hardware causes (failing GPU, loose cable) account for a small minority of cases.
Is the Black Screen of Death different from the Blue Screen of Death?
Yes — they are completely different errors. The Blue Screen of Death shows a blue background with a stop code and is caused by hardware failures, kernel driver crashes, or defective RAM. The Black Screen of Death shows a completely black display (sometimes with a cursor) and is almost always caused by Windows Explorer crashing, a display driver conflict, or a Fast Startup bug. The fixes are entirely different. Do not apply BSOD fixes to a black screen issue.
Can I fix the Black Screen of Death without reinstalling Windows?
Yes, in the vast majority of cases. Roughly 70% of black screen cases are resolved by Method 1 (restarting Windows Explorer) or Method 2 (disabling Fast Startup) — neither requires any reinstallation. Driver rollback, system restore, and startup repair resolve most remaining cases. A full Windows reinstall is rarely necessary for a black screen specifically.
What if the screen is black from the very start — before Windows loads?
A pre-boot black screen (before the Windows logo appears) is a different problem from a post-login black screen. Start by checking the monitor cable and input source (Method 6). If the hardware connections are fine, access the Recovery Environment from a Windows USB drive and run Startup Repair. A corrupted boot sector or boot configuration database (BCD) can prevent Windows from displaying anything at all during startup.
Does the Black Screen of Death mean my hardware is failing?
Usually not. Hardware is the cause in a small minority of black screen cases, and there are clear signs: "No Signal" on the monitor even though the PC is running, black screen on every monitor with every cable tested, or black screen persisting after a full Windows reset. If all software fixes fail, then a failing GPU becomes the likely diagnosis and physical hardware testing is the right next step.
Summary: Black Screen of Death Fix Order
- Ctrl+Alt+Delete → Task Manager → Run explorer.exe — fixes most cases instantly
- Disable Fast Startup — stops recurring black screens at startup
- Boot to Safe Mode, uninstall recent update or driver — essential if screen is always black
- Roll back or reinstall display driver — for GPU-related conflicts
- Run Startup Repair from Recovery Environment — for startup-only black screens
- Check monitor cable and Win+P display output — often overlooked, takes 30 seconds
- Disable Hybrid Sleep and Wake-on-LAN — for sleep/wake black screens
- Run sfc /scannow and DISM — for corrupted system files
- System Restore to before the black screen — rolls back to a known working state

Method 1 fixed it in literally 20 seconds. Black screen after login, cursor visible, desktop never loaded. Ctrl+Alt+Delete, Task Manager, File → Run new task, explorer.exe. Desktop came right back. I had no idea that's all it was. Bookmarking this for next time.
Had black screen every single morning on startup for three weeks. Method 2 — disabling Fast Startup — completely eliminated it. Haven't had it once since. Wish I had found this article sooner, I wasted so much time restarting over and over.
The Win+P shortcut saved me. Had a second monitor connected and Windows was sending everything to it while my main screen was black. Pressed Win+P a couple times, main screen came back. Zero software problems — just the wrong display mode. Would never have thought of that.
Called IT Cares after trying the first few methods myself. The tech connected remotely and fixed it in under 20 minutes — turned out to be an NVIDIA driver that Windows Update installed without asking. He rolled it back and disabled automatic driver updates. Excellent service, totally worth the $59.
