Restore a monitor that randomly goes black

In Windows 10, one of the most annoying problems you may encounter is a black screen because you don’t see an error code or message on the screen to give you a clue on how to start troubleshooting.

A black screen can occur for many reasons. It can be due to a recent graphics driver update problem, or it can happen when you install a feature update that is related to a compatibility issue. It can also be the result of an incorrect system update. It could also be a hardware problem related to the display, connectivity, or video adapter.

Regardless of the cause, there are several ways to determine the cause and solve this problem on Windows 10, whether you have access to the desktop or not.

In this Windows 10 guide, we’ll explain how to solve the black screen problem.


What causes the monitor to go black by accident?

What causes the monitor to go black by accident?

After extensively researching this problem and combining user reports, we’ve concluded that there are a number of reasons for this problem. Here are some of the reasons why your monitor can go black.

Faulty power supply: We know that the power supply is the most common reason why your monitor turns black. Since it powers the motherboard, it may not be supplying the voltage correctly.

Video cable: The video cable, whether it’s an HDMI or VGA cable that connects the monitor to your computer, maybe faulty or damaged. This usually results in a black screen when touched or even accidentally.

GPU: If you have a dedicated graphics processing unit (GPU) installed and the monitor is connected through it, this can also cause problems if it is damaged or connected incorrectly.

Overclocking: Overclocking can be useful for some users to increase basic performance, but it can also lead to complications such as the one discussed here.

Outdated operating system files: If the operating system files are corrupt or incomplete, they may be the cause of the problem. Outdated versions of Windows also find their way into these files.

Third-party graphics: If third-party graphics features (e.g. AMD, NVIDIA) are implemented, they may not synchronize with the operating system and cause various problems.

Power settings: System power settings determine how much power your computer consumes and where it stops working. If these power settings are not in sync with your usage, your monitor may go black.

Incorrect drivers: Graphics drivers are the main driving force for connecting the operating system to the hardware. If they’re outdated or corrupt, communication won’t work as well and you’ll have a lot of problems.

Third-party software: Although it happens very rarely, you may have third-party software installed on your computer that causes conflicts and strange problems like the one described here. This is where we can try to permanently troubleshoot and remove the software.

Power outages: Finally, if you have bad wiring or electrical interference in your home, your monitor may flare up instantly. Some alternative measures can be taken to correct this.

Make sure that you have an active Internet connection and that you are logged in as an administrator before proceeding with the solutions. In addition, as a precaution, we recommend backing up your data.

To solve black screen problems in Windows 10

Check the video cable and video connectors

In most cases, monitor problems are caused by a bad connection between your monitor and PC. To find out if this is the case, you should check your video cable and video connections. Here’s how to do it:

1.) Turn off the computer.
2.) Disconnect the video cable that connects the monitor to the computer.
3.) Check the connecting plugs on your computer and monitor.

(If one of the connectors on your device is bent or damaged, you need to take it to a repair shop.)

4.) Check the video cable for damage.
If the video cable is in good condition, connect the computer to the monitor.

Or, if you have another video cable available, try connecting both devices with a new cable. For example, if you are currently using an HDMI cable, try replacing it with a VGA cable.

If your monitor is still not working properly, see solution 2 below.

Check your computer’s power settings

A simple problem with the power setting can also cause the screen to randomly go black. Therefore, you need to check if the device has power-saving mode or screen saver enabled. Follow the instructions below:

If you are using Windows 7 or 8

1.) On your keyboard, press the key with the Windows logo on it. Then type “power options” and select “power options”.
2.) Make sure the power saving plan is not set to “power save”.
3.) Click the Change plan settings button.
4.) Make sure that the “Turn off screen” and “Put the computer in sleep mode” options are set to “Never”.
5.) On the keyboard, press the key with the Windows logo on it. Then type “screen saver” and select “Turn screen saver on or off”.
6.) Set the screensaver to None and press OK.
7.) Restart your computer to check the problem.

If the problem persists, keep reading and see Fix 3.

If you are using Windows 10

1.) On your keyboard, press the key with the Windows logo on it. Then type power and select power and sleep settings.
2.) Under “Screen” and “Sleep,” make sure the settings are set to “Never.”
3.) On the keyboard, press the key with the Windows logo on it. Then type “screen saver” and select “Enable or Disable Screen Saver”.
4.) Make sure the screensaver is set to No, then press OK.
5.) Restart your computer to make sure your monitor is now working properly.

If the problem persists, continue to solve it as follows.

Update your graphics driver

An outdated or defective graphics driver can also cause monitoring problems. It is important that you always use the latest graphics driver in order for your monitor to work properly. There are two ways to get the latest and correct graphics driver:

Option 1 – Download and install the driver manually:

To update the drivers this way, you will need computer knowledge and patience, as you will need to find the exact driver online, download, and install it step by step.

The manufacturer of your video card constantly updates the drivers. To get them, you need to go to the manufacturer’s support site, find the driver for a specific version of Windows (such as 32-bit Windows), and download it manually.

Once you have downloaded the correct drivers for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver.

Option 2 – Automatically update your graphics driver:

This is the fastest and easiest option. Everything is done with a few clicks – it’s easy, even if you’re new to the computer field.

If you don’t have the time, patience, or computer skills to manually update your graphics driver, you can do it automatically using third-party software.

Third-party software will automatically detect your system and find the correct drivers for it. You don’t need to know exactly what system is running on your computer, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake during installation.

Resetting your monitor to factory settings

If your monitor keeps shutting down, it’s unlikely that the monitor setting is the main problem, but you should still rule that possibility out. Here’s how to reset your monitor to factory settings:

1.) Press the Menu key on the monitor and select Menu.
2.) Go to Advanced Settings and select Factory Reset.

See if this solves your problem. If your monitor remains randomly black, your problem is probably due to a hardware failure. If this is the case, you should take your monitor or computer to a repair shop and get professional help.
