Experiencing a black screen while your computer is still running can be very frustrating. It might seem like a big problem, but many users face this issue. Often, the cause is related to the video card, driver updates, or loose cables.
This problem might happen after the computer has been on for a while or even randomly. Sometimes, you will still hear the fans running or sounds from the computer. Understanding the signs can help in finding the right fix.
There are several steps to try when you face this issue. Checking the video card, updating drivers, and inspecting cables can help. These simple actions might get your screen back to normal in no time.
Troubleshooting A Black Screen On Your Computer
1. Check the Obvious Stuff
Sometimes the simplest solution is the right one. Make sure your monitor is turned on and the brightness isn’t all the way down. Check that the power cable is securely plugged into both the monitor and the wall outlet. If you’re using a separate cable to connect your computer to the monitor (like HDMI or DisplayPort), ensure it’s properly connected at both ends.
2. Wake Up Your Display
Your computer might think your display is asleep. Try these quick tricks to wake it up:
- Move your mouse: Jiggle the mouse or press a key on your keyboard to see if the screen wakes up.
- Use the keyboard shortcut: Press the Windows key + P. This brings up the display settings. Use the arrow keys to cycle through the options and press Enter.
- Check for a loose connection: Gently wiggle the cable connecting your monitor to your computer. Sometimes a loose connection can cause the screen to go black.
3. Power Cycle Your System
A power cycle can often resolve temporary glitches. Here’s how:
- Turn off your computer: Shut it down completely.
- Unplug the power cord: Disconnect the power cord from the wall outlet.
- Wait a few minutes: Give it a short break, around 5-10 minutes.
- Plug the power cord back in: Reconnect the power cord to the wall outlet.
- Turn on your computer: Power it back up and see if the screen works.
4. Listen for Clues
Pay attention to the sounds your computer is making.
- Normal startup sounds: If you hear the usual beeps and fan noises, it suggests the computer is starting up correctly, and the issue is likely with the display.
- Unusual beeps: Beeps in a pattern often signal a hardware problem. Look up your computer’s beep codes in the manual or online to understand what they mean.
- No sounds at all: This could indicate a power supply issue or a more serious hardware problem.
5. Check External Devices
Sometimes, external devices can cause conflicts. Disconnect any unnecessary devices, such as printers, external hard drives, or USB hubs. See if this resolves the black screen issue.
6. Boot into Safe Mode
Safe Mode starts Windows with minimal drivers and programs, which can help identify if a software conflict is causing the problem.
- Restart your computer: As it’s starting up, repeatedly press the F8 key until you see the Advanced Boot Options menu.
- Select Safe Mode: Use the arrow keys to highlight Safe Mode and press Enter.
- Check if the screen works: If the screen works in Safe Mode, a recently installed program or driver might be the culprit.
7. Update or Roll Back Graphics Drivers
Outdated or faulty graphics drivers can cause display problems.
- Update drivers: Visit the website of your graphics card manufacturer (Nvidia, AMD, or Intel) and download the latest drivers for your card.
- Roll back drivers: If you recently updated your drivers, try rolling back to the previous version. You can do this in Device Manager.
8. Test with a Different Monitor or Cable
If possible, try connecting your computer to a different monitor or using a different cable. This helps determine if the problem is with your monitor or the cable itself.
9. Seek Professional Help
If none of these steps work, it’s time to call in the experts. A computer technician can diagnose the problem and recommend the best course of action.

Diagnosing and Troubleshooting
When a computer screen goes black but the system keeps running, finding the cause often reduces to either software or hardware issues. Follow these steps for identifying and fixing common problems related to black screens.
Identifying the Problem
Start by determining whether the issue is specific to your monitor or the entire system.
Connect an external monitor using an HDMI, DVI, VGA, or DisplayPort cable. If the external display works, the problem might be with the original monitor.
Use the Windows key + P to make sure you are not projecting to a different display. Press Ctrl + Alt + Del to see if the Task Manager opens. If it does, the issue might be related to your operating system, such as Windows 10 or 11, rather than your hardware.
Immediate Actions
If your screen still stays black, use keyboard shortcuts to wake it up.
Press Windows key + Ctrl + Shift + B. This can reset the graphics driver.
You might also try pressing the power button for around 10 seconds to force a shutdown. Then, reboot your computer.
If you hear beeps, count them. They might indicate specific issues based on your computer’s BIOS or UEFI beep codes.
Hardware Checks
Inspect all connections.
Ensure cables between the monitor and the computer are secure. Check for damaged cables or connectors.
Test with a different monitor if available.
Look at peripherals like the mouse or keyboard to see if they are causing problems. Disconnect everything except the monitor and then restart the computer to see if the issue resolves. Overheating can also cause black screens, so clean out dust from vents and fans.
Software and System Solutions
Boot into Safe Mode by restarting and pressing F8 or using the Windows Installation Media.
Once in Safe Mode, check for driver issues. Update or reinstall the graphics driver. Open Device Manager from the Control Panel, right-click on the graphics driver, and choose Update Driver or Uninstall Driver.
Run Windows Update to get the latest fixes.
Use System Restore to revert your system to a point before the black screen issue started if needed. Also, consider disabling Fast Startup in the Power Options.
If all else fails, reinstall the operating system to fix software-related issues.
FAQs
Why does my monitor go black but my PC is still on?
A black screen with the computer still running usually means there’s a problem with how your computer is talking to your monitor. It’s like they’re not on the same page! Here are the most common reasons:
- Connection issues: The cable between your computer and monitor might be loose or damaged. Try reseating it or using a different cable.
- Display settings: Your computer might think your monitor is asleep or turned off. Try pressing a key, moving your mouse, or using the Windows key + P shortcut to adjust display settings.
- Graphics driver problems: The software that controls your graphics card (which sends the picture to your monitor) might be outdated or have glitches. Try updating or rolling back your graphics driver.
- Monitor problems: The monitor itself could be faulty. Try connecting your computer to a different display to see if that fixes it.
- Power saving mode: Your monitor or computer might be going into power saving mode. Check your power settings and adjust them if needed.
If you’ve tried these and still have a black screen, it might be a more serious hardware issue. It’s best to consult a computer technician in that case.
What is the black screen of death?
The “black screen of death” is a scary term, but it basically means your computer has encountered a serious error and can’t show anything on the screen. Sometimes your keyboard might still light up, meaning the computer is getting power, but something is preventing Windows from starting properly.
