In this tutorial, learn how to fix Monitor randomly goes black.
Several customers have recently reported that their monitors have gone black for a brief period of time. This behavior has been reported to occur on a regular basis, ranging from every second to every few minutes. The problem is exacerbated by the fact that the monitor fails without regard to any specific event or time.
This problem was reported by many users to occur either when utilizing graphics heavily or at random. There is no formal declaration from official sources, according to our study. In this article, we’ll go over all of the possible causes for this problem on your computer.
What causes the Monitor to go Black Randomly?
We concluded that this issue happened for a variety of causes after doing comprehensive investigation and aggregating user reports. Some of the causes of your monitor going dark include, but are not limited to:
Bad PSU: The most common cause of your monitor going dark is a faulty power supply unit. Because this provides power to your motherboard, it’s conceivable that the right voltages aren’t being delivered.
Video cable: The video cable connecting your monitor to your PC, whether HDMI or VGA, may be broken or damaged. When touched, this usually results in a black screen, although it can sometimes happen at random.
GPU: If you have a dedicated GPU installed and the display is connected through it, it may cause issues if it is damaged or not correctly plugged in.
Overclocking: While overclocking might be beneficial for some users in terms of increasing core power, it can also come with problems, such as the one discussed above.
Outdated OS files: If the operating system files are faulty or missing, this could be the source of the problem. Windows versions that are no longer supported can also be found here.
Third-party Graphics Options: If third-party graphics boosting features (such as AMD, NVIDIA) are used, they may not be in sync with the operating system and cause problems.
Power settings: The power settings in your system determine how much power your computer will use and when it will stop using it. If these power settings do not match your consumption, you may experience issues such as the monitor going black.
Bad drivers: The fundamental driving force in linking your operating system to the hardware is graphics drivers. If they are obsolete or corrupt, communication will be hampered, and you will face a slew of problems.
Third-party software: Even though this is extremely unlikely, there may be some third-party software on your machine that is incompatible and generating strange troubles like the one described. Here, we can attempt to troubleshoot and permanently uninstall the software.
Power interference: Last but not least, if you have defective wiring or electrical interference in your home, your monitor may flicker for a brief period of time. To correct this method, there are a few more options.
Make sure you have an active internet connection and are logged in as an administrator before moving on to the solutions. We also recommend that you make a backup of your data just in case.
Solution 1: Checking HDMI/VGA Cable
It’s possible that your HDMI cable isn’t functioning properly or is damaged. The same can be said for your television or monitor, which may or may not be working. We’ll use some simple troubleshooting techniques to see if they can help us diagnose and fix the problem.
- Replace your HDMI cable with a new one. Before you go out and get a new one, see if the present one works on another system. If it doesn’t work, the cable is most likely damaged. Replace the cord and give it another shot.
- Changing the monitor or TV’s different input source may help. If you’re using a laptop as an input source, try connecting to it using a different laptop to see if it makes a difference. If the signal is detected on the other laptop, it is likely that your laptop has some misconfigurations or that the HDMI port is broken.
- You can also try to isolate the problem by seeing if the monitor/TV works with alternative inputs.
- This can be problematic if you’re utilizing an HDMI to VGA converter. Use a pure HDMI cable to ensure that the HDMI module on both your input and output is working properly.
Solution 2: Disabling Overclocking
Nowadays, overclocking is a popular component in many PC builds. In this case, the processor executes quick bursts of processing over a short period of time. The CPU reaches its threshold temperature during this time, and overclocking is disabled until the CPU is cooled again. Users reported that deactivating overclocking solved their problem with the monitor going black repeatedly. Although these options are supposed to boost the computer’s performance, they appear to have the opposite effect.
We recommend that you disable all types of overclocking and return your CPU to its original settings. In addition, make sure your PC isn’t running any computer-enhancing software. When attempting to ‘optimize’ the computer by deleting various critical processes, these apps have been known to interfere with the OS and graphics.

Solution 3: Updating Windows to the Latest Build
Microsoft publishes updates on a regular basis to repair bugs and add new features. It is suggested that you upgrade Windows straight away if you haven’t done it in a long time. There have been previous instances where the graphics system failed to function properly due to bugs introduced into the system.
When these problems are discovered, Microsoft developers work quickly to release updates that address the problem. The display appears to be in fine working order after installing the upgrades. Before continuing, make sure you’re logged in as an administrator.
1. To open the application, press Windows + S, then type “update” in the dialogue box.
2. The Settings menu will now appear. Check for updates by clicking the button. Your computer will now automatically look for and install any new updates that are available.
Note: To apply the updates, you’ll need an active internet connection. Also, depending on the size of the update, it may take some time.
Solution 4: Updating Graphics Drivers
Graphics drivers, as you might expect, are the major components that connect and relay instructions from your operating system to the graphics hardware. You will encounter stuttering and strange difficulties such as the monitor screen going dark if these are obsolete or corrupt. We’ll start by properly uninstalling the current drivers before attempting to install fresh ones.
PRO TIP: If the issue is with your computer or a laptop/notebook you should try using Restoro Repair which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption. You can download Restoro by Clicking Here
1. DDU (Display driver uninstaller) can be downloaded and installed from this source.
2. Start your PC in safe mode after installing Display Driver Uninstaller (DDU).
3. Select the first option “Clean and restart” after running the DDU. This will totally remove the current drivers from your machine.
4. After you’ve completed the uninstallation, restart your computer normally without using safe mode. Enter “devmgmt.msc” in the dialogue box by pressing Windows + R. Select “Search for hardware changes” from the context menu of any place. Drivers will be installed by default. Try relaunching the game to see if it resolves the issue.
5. The default drivers will not work in the vast majority of cases, so you must either install the latest drivers through Windows Update or go to your manufacturer’s website and get the latest ones.
Restart your computer after installing the drivers to see if the problem has been resolved.
Solution 5: Checking your PSU (Power Supply Unit)
The power supply unit (PSU) is the main component that receives AC power from an external power outlet and then delivers the correct voltage to other components in your computer. SATA connections, for example, may consume more power than the motherboard. If your power supply is faulty or not delivering electricity properly, you can encounter a variety of issues, ranging from your monitor blinking repeatedly to the computer crashing.
You could try another power supply for a while. Check to see if the problem persists while using that particular piece of hardware. Also, ensure sure the cable connecting the PSU to the mains energy outlet is changed. If the problem still exists, you should get your power supply checked. If it does, you can move on to the next step in the troubleshooting process, which is listed below.
Solution 6: Uninstalling/Disabling third-party programs
Third-party applications, such as NVIDIA GeForce Experience and AMD applications, are frequently packaged alongside graphics hardware and drivers. Almost all of these tools allow users to alter the visual settings in order to enhance or add custom features.
Despite their utility, they are known to cause problems with the system. Disable all third-party programs that are operating in the background, and if there are any options that allow you to manipulate graphics, make sure these are disabled as well. The following is the procedure for uninstalling these applications:
1. Enter “appwiz.cpl” in the dialogue box by pressing Windows + R and then tap Enter.
2. Once you’re in the program manager, look for the app that’s causing the problem, right-click it, and choose Uninstall.
3. Check to see if the problem has been resolved after removing the application.
Note: If you wish to reinstall the third-party application and don’t want to lose all of your settings, you can always save the temporary configuration file.
Solution 7: Changing Power Settings
The primary protocols or rules that tell a computer how much power to use and when to save it are known as Power Settings. These power settings could be adjusted to a value that is incompatible with your system or incompatible with your motherboard. In this approach, we’ll modify the power settings by navigating to the motherboard’s power settings.
1. To open the Run application, press Windows + R. Type “control panel” into the dialogue box and press Enter. This will open the control panel on your machine. Check that View by: is set to small icons in the top-right corner of the screen.
2. Select Power Options from the control panel.
3. This is where you’ll find the current power mode. Change it to High performance or Balanced if it’s set on Power saver.
4. If you’ve changed some of the internal settings of each plan in the past, go to Change plan settings and choose Restore default settings to this plan.
5. Save your changes and then depart. Check to see if the problem has been resolved by restarting your computer.
Solution 8: Checking your GPU
It is recommended that you check whether a third-party dedicated GPU (such as NVIDIA/AMD) is working properly and is properly connected if you have one installed on your computer. The fluctuating output to the monitor is known to be caused by a malfunctioned GPU that is frequently utilized and overclocked.
Disable your dedicated graphics and observe whether the problem occurs with your integrated graphics. If they do, it will aid us in determining the source of the problem. The procedure for disabling the specialized graphics is as follows:
1. Enter “devmgmt.msc” in the dialogue box by pressing Windows + R.
2. Look for Display adapters in the device manager, then right-click on the graphics card and select Disable device from the context menu.
3. Restart your computer once you’ve disabled the device to see whether the problem still exists.
Solution 9: Checking for Power Interference/Issues
Although this is the final method, it is equally vital as the others. Power interference is a common source of monitor jittering. You may check this by watching how the monitor reacts when you turn on a light or another electrical equipment.
If your monitor oscillates, it’s a sign that your wiring isn’t up to par or is quite old. A UPS (uninterrupted power supply) can help with this by regulating the voltage coming into your computer. If this resolves the issue, our diagnosis is correct.
Note: If none of the previous solutions work, it’s likely that your monitor has to be replaced.
Hope something helps you.
