What to do when your computer screen goes black
When a black screen in Windows 10 error occurs, the computer may still be on and functioning, but it may be frozen and incapable of accepting inputs, or it may just be off. A black screen in Windows 10 can appear at any time during use, immediately after booting, after or during an update due to a Windows update error, and at virtually any other time.
Some Windows 10 PCs have been rebooting to a black screen after installing the June 2019 cumulative update from Windows Update. This seems scary at first, but luckily there’s a quick fix that will solve your problem; Black Screen in Windows 10.
If your Windows 10 PC reboots to a black screen; Black Screen in Windows 10, just press Ctrl+Alt+Del on your keyboard. Windows 10’s normal Ctrl+Alt+Del screen will appear. Click the power button at the bottom-right corner of your screen and select “Restart” to restart your PC.
Causes of Black Screen in Windows 10
Unlike Windows errors that provide an error message, like blue screen errors, black screen errors don’t give you anything to go on. This situation can be caused by a wide variety of software and hardware problems, including:
- The display is off: Some displays will turn off automatically when no video input is received, which will result in a black screen if the computer stopped sending a signal momentarily.
- Broken Windows update: If you were trying to update Windows, or it was updating in the background, something may have gone wrong.
- Display adapter driver update: Rather than a general update problem, this error happens when you’re specifically trying to update your display adapter driver.
- Connection problems: If there’s a problem with your HDMI cable or the internal wires in your laptop, the screen will be black.
- Broken startup application: If the black screen happens when booting your computer, you may have an application set to run on startup that interferes with your display adapter.
- Malfunctioning hardware: Your video card, cables, monitor, display panel, or other components may be bad.
How to Fix a Black Screen in Windows 10
To fix a black screen in Windows 10, you need to narrow down why the screen is black and then fix the root cause. Many of these issues are pretty easy to fix without specialized tools or knowledge, but some are more complicated.
The following troubleshooting steps progress from easiest to most difficult, so you can start at the top and perform each step until your black screen is fixed or you reach a procedure that you aren’t comfortable with.
Test your monitor. If you’re using an external monitor, turn it off and on again. If the monitor doesn’t turn on, or it appears dead, then the monitor itself may be at fault. If it has an LED that indicates when the display is powered on, check to see if that LED is on and the right color. If the display doesn’t turn on, check the power cable.
You may also test the existing outlet by plugging another device to it or try a different power outlet.
Try to reboot your computer. If your Windows 10 computer boots directly to a black screen, especially after installing an update, you may be able to fix it with a simple reboot.
- Press CTRL + ALT + DEL on your keyboard.
- Click or tap the power icon in the bottom right corner of the screen.
- Click Restart.
If the screen remains black when you press CTRL + ALT + DEL, just move on to the next step. This solution won’t work for you.
Restart your computer from a completely powered off state. Your computer may appear to be on when it’s actually stuck attempting to resume from sleep or standby mode. Push and hold the power button for at least five seconds, look for signs that the computer has turned off like the lights and fan turning off, and then unplug it from power. Wait a few minutes, plug it back in, turn it back on again, and see if the display works.
Check your brightness settings. If you’re using an external monitor, check the brightness settings using the built-in controls. If you’re using a laptop, use the brightness function keys. The brightness may be set too low to see anything on the screen.
Try a different video output. If your computer has multiple HDMI outputs, try a different one. If it has USB-C, you can also try using a USB-C to HDMI adapter.
Try a different monitor. Whether you’re using a desktop or a laptop, try plugging in a different display. If you don’t have one, you can connect to any television that has an HDMI input. If that fixes the black screen problem, then your monitor or laptop display is bad.
If your monitor has multiple inputs, try a different input on the monitor. Double-check that you have the monitor set to the correct input as well.
Try a different HDMI cable. If you’re using an external monitor, switch to a different HDMI cable. Use one that you know works if possible, like an HDMI cable that you use with a video game system or Blu-ray player.
Refresh the connection to the monitor. Press Windows key + CTRL + SHIFT + B on your keyboard. This shortcut causes Windows 10 to restart your video driver.
Wake up the display. If you’re using a tablet, such as a Surface Pro, press the volume up and volume down keys simultaneously three times in a row. If you do it quickly enough, you’ll hear a beep, and the display will reactivate if this was the problem.
Bring up the Project menu and choose a display. If your computer is on and Windows 10 is responsive, and the display just isn’t working, you can press the Windows key + P to access the Project menu. You won’t see it because the screen is black, but pressing Enter will switch to a different mode. Repeating this step four times will cycle through all of the options. If your display starts working, you can stop at that point.
Disconnect your peripheral devices. Try disconnecting all of the peripheral devices that you have connected to your computer, including removable drives, SD cards, cameras, printers, hubs, and everything else. Then restart the computer, and see if the display works. If it does, reconnect your devices one at a time until you find the one that’s causing trouble. That device may need a driver update, or it may need to be replaced.
Restart the Windows Explorer process. If your screen is black, but you have a working mouse cursor and can access the Task Manager, your Windows Explorer process may be frozen. Opening the Task Manager and restarting Windows Explorer may fix this problem.
Use Safe Mode to troubleshoot. Restart your computer in Safe Mode by shutting the computer off and restarting it three times. When presented with the Windows Recovery Environment, select Troubleshoot > Advanced options > Startup settings > Restart. Then wait for your computer to reboot and select option 5 for Safe Mode with Networking.
If the display works in the Recovery Environment and Safe Mode, use Safe Mode to disable startup items and services until you determine which one is at fault.
Rollback your graphics driver. If your display works while in Safe Mode, then boot into Safe Mode and roll back your graphics driver. After you have reverted to an earlier version, try rebooting.
Disable fast startup. Windows 10 has a fast startup feature that’s designed to do exactly what the name implies, but it can also cause a black screen error. If you upgraded hardware like RAM before experiencing a Windows 10 black screen error, this is likely the cause.
- To disable fast startup:
- Start Windows in Safe Mode.
- Navigate to the Control Panel.
- Open System and Security.
- Click Power Options.
- Select Choose what the power button does from the left pane.
- Click Change settings that are currently unavailable.
- Remove the check from the Turn on fast startup box.
- Click Save changes.
- Restart your computer.
Use System Restore. Access System Restore the same way you accessed Safe Mode, but click System Restore instead of Startup Settings. Using System Restore, roll back to your most recent known working restore point. You can also scan for affected programs at the same time.
Uninstall Windows updates. Re-access the Recovery Environment, but select Uninstall Updates. From there, select uninstall latest feature update, sign in if prompted, and click the uninstall feature upgrade button.
If you still experience a black screen after following all of these steps, you may have defective hardware. Consult with your hardware manufacturer or Microsoft customer support for more information.
Resolving Black Screens During or After Windows 10 Installation
Black screens are sometimes encountered when you install Windows 10 for the first time. This may happen during the Windows 10 install process or just after the Windows setup is complete; Black Screen in Windows 10. There are a few potential causes.
Probable cause: Setup is still in progress. If you have a large personal data file set that you are migrating from a previous Windows installation, the Windows 10 setup process could take several hours.
Possible solution: Observe the hard drive activity LED closely to determine if the computer is still working. If the LED is still blinking, it means setup is probably still busy working on sorting through your files and determining what to move and what to keep. This is a good sign, which means you should wait a bit more. If setup goes beyond 2 to 7 hours, then the setup may be stuck.
Probable cause: Setup is stuck. For whatever reason, the setup process is hung up on something and can’t proceed further.
Possible solution: Power down your computer completely and try again. Follow these steps:
- Power down the computer completely. If it won’t shut down, hold the power button for 5 to 10 seconds until it shuts down.
- Disconnect from the internet by unplugging the Ethernet cable or switching off the wireless adapter (if possible). See this post for more information on disabling LAN connections before a Windows 10 setup.
- Disconnect all unnecessary peripherals from the PC. Remove external hard drives, game controllers, phone chargers—pretty much everything but the keyboard and mouse.
- Remove power from your computer. Disconnect the power cord from the outlet. If it’s a laptop, remove the battery, too. Wait at least 30 seconds before plugging your computer back in. (Note: If you have the time to spare, leave the computer unplugged for up to an hour. This will help if your computer started to get overheated.)
- Connect the system to power again, but leave the internet disconnected. Power on the computer.
- Hopefully, Windows will try to resume or restart the Windows 10 setup process.
- If the installation completes normally and you get to a Windows desktop with a Start menu and everything, go ahead and reconnect to the internet to finishing downloading and applying updates.
- If the setup rolls back to your previous version of Windows, then try upgrading manually using the Media Creation Tool or a ISO file.
Probable cause: The black screen is caused by a device driver or hardware performance issue.
Possible solution: Try booting into Safe Mode. See the section below on How to Use Safe Mode to Troubleshoot Black Screens.
Fixing Black Screens During Windows Out-of-Box-Experience
The OOBE is the Windows Out-of-Box-Experience, and it’s not unlike an out-of-body experience. It’s a weird transitionary phase where magical things happen but things aren’t all there yet.
If you get a black screen during the OOBE, there are a few things you can try.
Probable cause: Video output is being routed to a different display adapter or a different output (e.g. HDMI-to-DVI or DisplayPort-to-VGA). Sometimes, the display configuration that you had in your previous Windows installation doesn’t carry over properly to Windows 10.
Possible solution: Try physically disconnecting the video cable from one adapter or output and trying another.
- If you have a spare monitor, you can try connecting to that instead.
- If you normally connect to a discrete graphics card, but your computer has an onboard graphics adapter, switch to it instead. You can always update the driver after setup is complete for your discrete card through Windows Update or the manufacturer’s website.
- If you are using a television set, check to make sure it is turned on and set to the input for the computer; video output may be going to the TV.
Probable cause: Video output is being sent to the wrong display. If you have multiple displays connected, the Windows setup can sometimes get confused.
Possible solution: Try projecting output to another monitor by pressing Windows key + P then choosing the appropriate option.
