Windows 11 Black Screen of Death: Causes & Fixes

Updated 6 November 2026 · Standard formula, shown below

Windows 11’s black screen of death (BSOD) is a startup failure where the screen stays black, often with a spinning cursor, after the BIOS logo. It can be caused by driver issues, faulty updates, or hardware problems. This guide explains the common causes and provides step-by-step fixes to get your PC back to normal.

What Is the Black Screen of Death?

The black screen of death is a colloquial term for a Windows startup failure where the system appears to boot but the display remains black. Unlike the traditional blue screen of death (which shows an error code), a black screen often gives no error message, making it harder to diagnose. It can appear before the login screen, after login, or even after a period of normal use.

Common Causes

Several issues can trigger a black screen on Windows 11:

Graphics driver problems: A recent driver update or a corrupted driver can prevent the display from initializing.
Windows Update failures: A partially installed update can leave system files in an inconsistent state.
Fast Startup glitches: The hybrid shutdown feature can sometimes cause the system to hang on wake or boot.
Hardware issues: Loose cables, a failing GPU, or a defective monitor can cause a black screen.
Corrupted system files: Malware or accidental deletion can damage critical Windows components.

How to Fix a Black Screen Before Login

If the black screen appears before you see the login screen, try these fixes in order:

Force a restart: Press and hold the power button for 10 seconds to turn off the PC, then turn it back on. This often clears temporary glitches.
Check your monitor and cables: Ensure the monitor is on and the cable (HDMI, DisplayPort, etc.) is securely connected. Try a different cable or port if possible.
Boot into Safe Mode: If the screen remains black, restart your PC three times, interrupting the boot process each time. On the third restart, Windows should enter the Recovery Environment. From there, go to Troubleshoot > Advanced options > Startup Settings > Restart, then press 4 or F4 to boot into Safe Mode. In Safe Mode, you can uninstall recent updates or roll back drivers.
Uninstall recent updates: In Safe Mode, go to Settings > Windows Update > Update history > Uninstall updates. Remove the most recent quality or driver update, then restart normally.

How to Fix a Black Screen After Login

If you see the login screen but the screen goes black after entering your password, the issue is often with the graphics driver or a startup app. Try these steps:

Restart the graphics driver: Press Win + Ctrl + Shift + B to reset the graphics driver. This often restores the display if the driver has crashed.
Boot into Safe Mode: If the shortcut doesn’t work, force a restart and boot into Safe Mode as described above.
Disable fast startup: In Safe Mode, go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable, then uncheck Turn on fast startup.
Roll back or reinstall the graphics driver: In Safe Mode, open Device Manager, expand Display adapters, right-click your GPU, and choose Properties > Driver > Roll Back Driver. If that’s unavailable, download the latest driver from your GPU manufacturer’s website and install it.

Using System Restore and Startup Repair

If the above steps don’t work, you can try system-level repairs:

System Restore: From the Recovery Environment, choose Troubleshoot > Advanced options &em>System Restore. Pick a restore point from before the problem started.
Startup Repair: In the same menu, choose Startup Repair. This tool scans for and fixes common boot issues automatically.
Command Prompt: For advanced users, you can open Command Prompt from the Recovery Environment and run sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth to repair system files.

When to Check Hardware

If software fixes don’t resolve the issue, the problem may be hardware-related. Check the following:

RAM: Reseat the memory modules or test with one stick at a time.
GPU: If you have integrated graphics, try connecting your monitor to the motherboard’s video port. If the screen works, your dedicated GPU may be failing.
Power supply: A failing PSU can cause intermittent black screens. Listen for unusual noises or check if the PC shuts down under load.
Monitor: Test with a different monitor or TV to rule out a display issue.

Frequently Asked Questions

Why does my Windows 11 screen go black but the PC is still running?

This usually indicates a graphics driver crash or a display connection issue. Try pressing Win + Ctrl + Shift + B to reset the driver. If that doesn’t work, check your cables and try a different port. If the problem persists, update or reinstall your GPU driver.

Can a black screen be caused by malware?

Yes, certain types of malware can disable the display or modify system files to cause a black screen. If you suspect malware, boot into Safe Mode and run a full antivirus scan. You can also use the offline Windows Defender scan from the Recovery Environment.

Will I lose my files if I reset my PC to fix the black screen?

If you choose the Keep my files option during a reset, your personal files will be preserved, but installed apps and settings will be removed. However, it’s always wise to back up your data before attempting any major repair, especially if you’re using Command Prompt or recovery tools.

How long does a black screen last after a Windows update?

It can last a few minutes while Windows finishes applying updates. If it lasts longer than 30 minutes, force a restart and boot into Safe Mode. Then uninstall the recent update to see if that resolves the issue.

Is the black screen of death the same as the blue screen of death?

No. The blue screen (BSOD) shows a stop code and typically indicates a system crash. The black screen often occurs during boot or after login and may not show any error. The causes and fixes can overlap, but the black screen is more often related to display or driver issues.
