Computer Screen Randomly Goes Black - 9 Fixes (2023)

Navigating through the digital realm can be an exhilarating experience, but what happens when your computer screen unexpectedly plunges into darkness? In this article, we explore nine practical fixes to combat the perplexing phenomenon of a randomly blacking computer screen. Join us as we shed light on this enigma and restore the radiance to your digital existence.

Check power settings: Ensure that your computer’s power settings are not set to turn off the display after a certain period of inactivity. Adjust the settings to a longer time frame or set it to ‘never’ if necessary.

Checking video cable and ports

Checking Video Cable and Ports:

1. Ensure that the video cable is securely connected to both the computer and the monitor. A loose connection can cause intermittent blackouts.

2. If you’re using an HDMI cable, try using a different HDMI port on the monitor or computer to rule out a faulty port.

3. Check the cable itself for any visible damage or fraying. If you spot any issues, consider replacing the cable.

4. Update your graphics driver to the latest version. Outdated drivers can sometimes cause display problems. Visit the manufacturer’s website to download and install the latest driver for your GPU.

5. Adjust your computer’s power settings to prevent the screen from turning off automatically. Open the Control Panel, search for “power options,” and select the appropriate settings for your needs.

Remember, troubleshooting display issues can involve multiple factors, so it’s important to try these steps along with the other fixes mentioned in this article.

The computer screen going black randomly could be a sign of a loose or faulty connection between the graphics card and the monitor.

Adjusting computer power settings

Adjusting Computer Power Settings

To adjust your computer’s power settings, follow these steps:

1. Press the Windows key + X and select “Power Options” from the menu.

def monitor_check():

    while True:

        # Check if the screen is black

        if is_screen_black():

            # Attempt to wake up the screen

            try:

                wake_screen()

                print("Screen woke up successfully!")

            except:

                print("Failed to wake up the screen.")
        # Wait for a specific interval before checking again

        time.sleep(5)
def is_screen_black():

    # Code to determine if the screen is black

    # This can involve checking for specific pixel colors or querying system APIs

def wake_screen(): # Code to wake up the screen # This can involve sending appropriate signals or interacting with system APIs

This code is a simple example that continuously checks if the screen is black. If it detects a black screen, it tries to wake it up using the `wake_screen` function. However, please note that this code is not guaranteed to solve the issue, as the underlying cause may require specific hardware or software troubleshooting.

Factory resetting the monitor

If your computer screen randomly goes black, factory resetting your monitor can often resolve the issue.

To do this, first locate the power button on your monitor and turn it off. Unplug the power cord from the back of the monitor and wait for about 30 seconds.

While waiting, double-check that the connectors between your monitor and computer are securely connected.

Next, plug the power cord back in and turn on your monitor.

If the issue persists, you may need to factory reset the monitor. To do this, refer to the user manual or visit the manufacturer’s website for specific instructions.

Factory resetting the monitor will restore it to its default settings, which can help eliminate any software or configuration issues that may be causing the random blackouts.

Remember to also check for any driver updates for your monitor and graphics card, as outdated drivers can sometimes cause display problems.

Repairing corrupt system files

1. Run the System File Checker tool: Open the command prompt as an administrator and type “sfc /scannow“. This will scan and repair any corrupted system files.

2. Use DISM tool: Open the command prompt as an administrator and enter “dism /online /cleanup-image /restorehealth“. This will repair any damaged Windows image files.

3. Perform a clean boot: Temporarily disable startup programs to determine if any third-party software is causing conflicts. Press the Windows key + R, type “msconfig“, go to the “Services” tab, check “Hide all Microsoft services,” then click “Disable all.” Restart the computer.

4. Update drivers: Visit the manufacturer’s website for your graphics card, monitor, and other relevant drivers. Download and install the latest versions.

5. Check power settings and cables: Ensure that the power plan is not set to turn off the display. Additionally, check that all cables and connectors are secure.

Remember to restart your computer after implementing any changes. These fixes should help resolve the issue of a computer screen randomly going black.
