How to Fix a Black Screen on Your Computer: A Comprehensive Guide

Reading time: 6 minutes
In today’s digital age, computers are an integral part of our daily lives. Whether you’re using a custom-built PC or a personal laptop, these devices serve as our gateway to online shopping, virtual classrooms, remote work, and much more. However, like any technology, computers can encounter issues, and one of the most frustrating problems is the dreaded “black screen of death.”
In this comprehensive guide, we’ll explore the black screen of death, its common causes, and provide step-by-step solutions to get your computer back up and running.

What is the ‘black screen of death?’

The black screen of death occurs when your computer is stuck on a blank, black screen. In this state, the system becomes unresponsive to commands or button prompts. This issue can arise due to various reasons, often stemming from system errors that conflict with the computer’s operating system (OS) protocols.
Repeatedly forcing a computer to shut down can lead to file corruption or hardware damage, which are primary indicators that it might be time to consider buying a new laptop or desktop. While other minor issues can also slow down your computer, a complete system diagnostic is usually the best way to identify and resolve problems.
If your computer consistently freezes at a black screen, it’s crucial to identify and address the main issues promptly to prevent long-term damage to your PC.

Reasons for a black screen on your computer

Most often, a computer black screen occurs due to recent changes made to the PC. Here are some common reasons why you might be experiencing a black screen:

1. Connection issues with the monitor

Sometimes, a black screen occurs due to an interrupted connection between the computer and its display monitor. This is particularly common for desktop users who may accidentally dislodge the cable from its proper port on either the computer case or the monitor.
This issue can also arise when using an external monitor for a laptop, especially if the connecting cable is damaged.

2. Display device or adapter problems

A faulty display device or video adapter can prevent a computer from displaying images, resulting in a black screen. This is often the case when the PC produces sounds normally but cannot project any visuals.
A display device is an external apparatus that produces visual output, such as an LCD monitor. On the other hand, a video adapter is dedicated hardware - such as a graphics card - that creates those images before sending them to a display device.

3. Faulty system update or software installation

A system update or new software installation can sometimes force a black screen error. This usually happens due to conflicting commands or coding that disrupt the computer’s main programming, interrupting critical processes.
It’s always a good practice to back up your important files before making any major changes to your PC’s system.

Ways to solve the black screen of death

The ideal fix can be applied by identifying the most likely causes of your computer’s black screen. Some solutions may require tweaks to the computer’s system, including the BIOS (Basic Input/Output System), depending on the issue.
Consider external causes first, such as a damaged display cable, before exploring technical possibilities. Here are some possible ways to resolve a frozen black screen on your computer:

If the black screen occurs while booting up the computer before Windows sign-in

1. Fix connection issues with the monitor
  • Check the computer’s video cable for any external damage.
  • If there’s no visible damage, remove and reconnect the video cable from the computer to the monitor.
  • If the screen is still blank, test both the cable and the monitor:
    • Cable: Use another cable to connect the computer with the monitor. If the monitor works, the initial cable is damaged and needs replacement.
    • Monitor: Test the video cable between the computer and a different monitor (e.g., TV). If the new monitor displays images perfectly, the original monitor may be damaged and need replacement.

2. Refresh the screen via Windows key sequence

  • Click the CapsLock or NumLock keys to see if any indicator light turns on.
  • If any of the keys’ lights turn on:
    • Press Ctrl + Alt + Delete to prompt the administrator menu.
    • Select your account and sign in as usual.
    • If unable to sign in, click the "Power" icon and choose "Restart" to reboot the PC.
    • If the computer freezes at a black screen again, forcibly shut down the PC by pressing and holding the power button for about 10 seconds.
  • If none of the keys light up:
    • Manually shut down the computer by pressing its power button for about 10 seconds.
    • Remove the power adapter from the computer and its power source for about 30 seconds.
    • Plug it back in, then restart.

3. Roll back the display driver/adapter (via Safe Mode)

  • A recent change to your PC, particularly a Windows update, can prevent the display adapter from functioning correctly.
  • If you’re still stuck on a black screen, restart your computer in Safe Mode.
  • In Safe Mode:
    • Open the Search bar and type “Device Manager.”
    • Select the Device Manager program and find Display Adapters.
    • Right-click on the suspected display adapter and open Properties.
    • Find the Driver tab, select Roll Back Driver, and confirm.
    • Restart the computer to see if the black screen problem has been resolved.

4. Prompt a System Restore (Automatic Repair mode)

  • After multiple forced shutdowns, the computer will automatically enter its Automatic Repair phase during the next restart.
  • If the Automatic Repair screen appears, you can instruct Windows to return to its previous working state via System Restore:
    • Click on Advanced Options.
    • Go to Troubleshoot.
    • Proceed to Advanced Options again.
    • Choose System Restore.

If the black screen occurs after successfully signing in to Windows

1. Refresh the screen via Windows key sequence

  • Press the Windows key + Ctrl + Shift + B to force a refresh of the video display/adapter.
  • You should hear a short beep before the screen turns off and restarts.

2. Restart the Windows Explorer program

  • If a frozen Windows Explorer program could be causing the black screen:
    • Press Ctrl + Alt + Delete to open the admin menu.
    • Select Task Manager.
    • Open the Processes tab, highlight Windows Explorer, right-click, and choose Restart.
  • If the black screen persists, try starting a new Windows Explorer program:
    • In Task Manager, open File in the top-left corner.
    • Choose “Run new task.”
    • Type “explorer.exe” and click “OK.”

3. Roll back the display driver/adapter (via Safe Mode)

  • Follow the same steps as mentioned earlier for rolling back the display driver in Safe Mode.

4. Prompt a System Restore (Automatic Repair mode)

  • If the computer enters the Automatic Repair screen after multiple failed starts:
    • Choose Advanced Options on the screen.
    • Select Troubleshoot.
    • Click on Advanced Options again.
    • Select System Restore to revert Windows to a previous working state.

5. Uninstall recent updates (via Safe Mode)

  • To remove recently installed updates that might be causing issues:
    • Open the computer in Safe Mode.
    • Click on the Start/Windows icon, then go to Settings.
    • Choose Update & Security, and open Windows Update.
    • Click on “View update history” and proceed to Uninstall Updates.
    • Select the recently installed update to be removed, then prompt Uninstall.
    • Restart the computer to see if Windows can now start up normally.

Conclusion

Resolving a black screen issue can be challenging without identifying its probable causes first. In some cases, users might need to make changes inside the computer’s BIOS, which can be intimidating for some users.
A computer boot using a USB can also be performed if the PC still fails to resolve its black screen issue. However, if you’re uncomfortable with these advanced techniques, it’s best to consult a professional technician to avoid risking damage to your computer.
Remember, prevention is always better than cure. Be cautious when downloading third-party files or apps that might seem suspicious. Whenever possible, install new programs directly from official sources, and back up your computer regularly to safeguard important files from corruption.
If you’re in the market for a new, reliable computer that’s less likely to encounter these issues, consider the HP Pavilion Plus Laptop 14-ey1067nr. With its powerful AMD Ryzen™ 7 processor, 16 GB of memory, and 512 GB SSD storage, it offers smooth performance for all your computing needs.
