What factors cause the monitor to go black randomly?

How to fix monitor randomly going black? 10 solutions

If your monitor suddenly turns black, there are also some methods you can attempt to resolve the problem. Check out the following solutions to get out of this trouble.

Solution 1: Check HDMI/VGA Cable

If your monitor randomly goes black, there is a chance that your HDMI or VGA cable is the problem. To check if your cable is the issue, first, try disconnecting both cables and plugging them back in. If the problem still occurs, you can test your cable by connecting an external monitor to the same port on your computer and see if the issue persists. You may need to change your cable if none of these fixes works.

Solution 2: Disabling Overclocking

If your monitor randomly goes black, it could be due to overlocking. Follow these steps to disable overclocking:

  1. Open the processor options in your computer’s BIOS. This will let you modify the processor’s settings.
  2. Disable “Overclocking” from the list of options.
  3. Save and exit the BIOS setting.
  4. Try performing a stress test again and see if the issue persists. If it does, your computer may need new cooling or other repairs.

Solution 3: Replace The Battery If It Is Too Old

If your monitor seems to be randomly going black, there is a chance that the battery is too old and needs to be replaced. To test if this is the case, follow these steps:

  1. On your monitor, press the power button for about five seconds. If the screen goes blank, then you need to replace the battery. If you see a blue light coming on after pressing the power button but before the screen goes blank, then the battery is still good and you can continue with step 2.
  2. Disconnect your monitor from your computer by unplugging both cables from the back of your monitor.
  3. Open up your laptop or desktop and locate your battery (it will likely be a small white or silver object).
  4. Replace your outdated battery with a fresh one per the manufacturer’s recommendations.
  5. Reattach your monitor to your computer by plugging in both cables and turning it on. If everything works fine, congratulations!

Solution 4: Upgrade Graphics Drivers

If your monitor randomly goes black, there might be a problem with your graphics drivers. Many times, this can be resolved by upgrading your drivers. If you want to update your graphics drivers, do the following:

  1. Download the most recent driver for your card or chipset from the manufacturer’s website.
  2. Install the driver according to the instructions provided by the manufacturer.
  3. If necessary, restart your computer.
  4. Check if the problem persists after upgrading your graphics drivers. If not, you can try troubleshooting other issues first before upgrading your graphics drivers.

Solution 5: Factory reset your monitor

If your monitor is not responding or seems to have a problem, it might be time for a factory reset. This will clear all the settings and data on the monitor and should solve any problems. Follow these steps to factory reset your monitor:

  • Turn off your monitor.
  • Hold down the power button until the power LED turns off.
  • Wait two seconds, then release the power button.
  • Press and hold the Menu button until the Power Off menu appears.
  • Select Factory Reset.
  • Release the Menu button and press the Enter key.
  • The monitor will restart and you will be asked to choose an exit mode.
  • Choose OK to confirm and your monitor will factory reset.

Solution 6: Upgrade Windows/Your Operating System To The Latest Version

If you’re experiencing problems with your monitor going blank or randomly turning off, it might be time to upgrade to the latest version of Windows. Here’s how to do it:

  1. Click on the Start button and type “update” into the search box. You’ll see a list of results that show you all of the available updates for your computer.
  2. Double-click on one of the updates to open the update page for that particular package. If there are any additional steps you need to take before installing the update, they will be detailed on this page.
  3. Once you’ve completed all the required steps, click on “Install”. Your computer will now start downloading and installing the update.
  4. After the update has been installed, restart your computer so that it can apply these changes.

Solution 7: Repair corrupted system files

If your computer’s monitor randomly goes black, there is a good chance that the system files on your hard drive are corrupted. This can be caused by a number of different factors, including a virus, a power outage, or simply incorrect file permissions. To repair the system files and restore normal operation to your monitor, follow these simple steps:

  1. Boot your computer into Safe Mode. Safe Mode will allow you to access the operating system without any programs running in the background.
  2. Run a scan for viruses using an antivirus program. Once the scan is complete, remove any suspect files from your hard drive.
  3. Open Windows Explorer and navigate to C:\WINDOWS\system32\drivers\etc\. Scroll down until you find “hosts”. Right-click on “hosts” and select “Copy”.
  4. Open Notepad and paste the text from “hosts” into it. Make sure all of the quotes are marked correctly and that each line is separated by a comma. To find particular words or phrases, press Ctrl+F on a PC or Command+F on a Mac.
  5. Click on the “Apply” button and then click on “OK”.
  6. Close Windows Explorer and reboot your computer.

Solution 8: Change Computer Power Settings

Computer screens often go black or become distorted when the power to the monitor is cut suddenly. This can occur when a user turns off their computer without properly disconnecting the power cord, or when a power outage occurs. To get around this issue, be certain to use the proper power settings for your computer monitor.

Some common power settings for monitors are:

Power Off Timer: This allows you to set a timer that will shut down your computer after a certain amount of time has passed. This can help prevent sudden shutdowns that could damage your computer screen.

Low-Power Mode: If you rarely use your monitor and would like to save energy, try setting it to low-power mode. This will reduce the amount of energy needed by the monitor, but it may not be as effective in terms of image quality.

Solution 9: Check External Power Supply

An external power supply is sometimes the only solution to a monitor that randomly goes black. If your PC has a built-in graphics card, you may not need an external power supply. In some cases, you can check if your monitor needs an external power supply by plugging it into another outlet and testing the voltage. If the voltage is low, your monitor might need an external power supply.

Solution 10: Uninstalling/Disabling third-party programs

If you are experiencing random blackouts or your monitor is just going black for no reason, there may be a third-party program affecting your computer. To uninstall these programs, follow the steps below:

  1. Click the “Start” button and type “MSConfig” in the search bar.
  2. When the “Microsoft Configuration Utility” window opens, click on the “System” tab and then on the “Administrative Tools” sub-tab.
  3. Choose “Uninstall a Program” from the menu and press the “Next” button.
  4. Scroll down until you see the third-party program that you want to uninstall and select it using either the cursor or the mouse pointer.
  5. Click on the “Uninstall” button next to that program and wait for it to uninstall before clicking on the “Close” button in Microsoft Configuration Utility. Restart your computer after uninstalling all of your third-party programs to make sure that they are completely gone.
