The screen goes intermittently black and then returns to normal within a second. It could happen from once to multiple times per day. The most frustrating part is that there is no indication of errors that can help you determine the reason or fix the issue.
Some users claim to see the cursor of their mouse when they make a mistake, while others have a dark screen.
Some users report that their monitor’s LED begins flashing. Other reports claim that everything, including the lamp on the monitor, fades to a black streak.
No matter the specifics or the details, a blackout on a screen is possible due to various causes. Find out which of these triggers yours Monitor Turns Black for a Second.
Monitor Turns Black for A Second (Causes and Solutions)
Verify Your Connections
If you’re fortunate to get the black screen, it is due to an insecure connection.
Shut off the computer, pull the cables out, and begin examining the cables as your first step.
Examine the cords to find corrosions, bends, cuts, and other indications of wear and tear.
If there’s nothing to indicate a problem Try pulling the cable in length to see if your internal circuit is running short.
Make sure that the plastic cover is sealed and not exposed.
Next, you should go to the ports located at the rear of the tower and scan the ports for signs of deformation or unstable.
It is also possible to replace your cables by using a spare or test your current cable using a different device or port to see if it changes.
A different cable type could also accomplish the trick, should that be an alternative.
For instance, connect your monitor using the HDMI cable if you’re using VGA.
Based on the issue, you may bring your device to a repair shop to upgrade its ports or buy an entirely new cable.
If all seems well, everything is fine, move on to the next step.
Check Your Monitor
Before you move into more complex problems, it’s good to test your display with another tower before you move into more complex problems or reverse the process. You can borrow a friend’s monitor to test it on your case.
This allows you to rule out the possibilities and help you find the solution faster.
Try reducing the brightness of your monitor to see if the screen functions are gone.
Sometimes your monitor is old, expensive, or inefficient for extended hours or at its maximum capacity.
It gets overloaded when you put too much pressure on it.
Reducing brightness is an effective solution to rid yourself of this problem.
Re-evaluate The Cables
HDMI, VGA, DVI, and others video controllers transmit audio or video signals.
If these signals can’t get through to your screen, the screen will become black.
This could be due to using an adapter, an unsuitable cable or too long, or a poor quality one.
To eliminate those possibilities, increase the cable’s AWG size, and make sure it’s not more than seven feet.
Remove the receivers, adapters, or splitters in the circuit and check to see if the issue persists.
Start Your PC In The Safe Mode
While it isn’t the ultimate solution, this Method serves as a diagnostic tool to determine the cause of the issue.
A safe Mode is an option for booting that disables the non-essential settings, apps, and widgets to boot the OS in its basic state.
If you don’t notice the stuttering display, in this case, it’s a sign that you’re dealing with an obvious issue, and you should not be focusing on the specific hardware ones.
Here’s how to make use of it:
- Visit the Windows Settings through the Start menu.
- Select ” Update & security” and select ” Recovery.”
- Click the ” Restart Now” button under the “Advanced Startup” header ” Advanced Startup” header.
- You will be taken to a blue screen, where you will be able to select between Startup options.
- Enter F4 in Mode Safe Mode, then wait till the PC starts to reboot itself.
Change the Video Card Driver on your computer.
Another common reason for an intermittently dark screen is your driver for your graphics card.
If they’ve been updated recently or replaced, you might be on damaged files. If you’ve not updated them in many years, then it’s likely that your drivers are out of date.
In both instances, the driver ceases to respond to the monitor, turning off the images frequently.
Try these suggestions to determine whether you are experiencing this issue:

Make sure to restart your Windows Explorer.
As you may know, Windows Explorer is a graphical interface that runs on your OS that allows you to manage your folders and files.
However, certain of the graphics functions are quite resource-intensive and cause pressure on your CPU and working memory.
This means that your computer could slow at a snail’s speed and behave strangely in how it displays things.
It’s recommended to restart the tool and check whether the headache is gone.
- Click the keys Ctrl, Alt, and delete simultaneously to launch your Task Manager. (You can also search for its name within the Start menu if the shortcut does not work.)
- Scroll through the list of applications to locate Windows Explorer.
- Right-click it and hit ” Restart.”
Make Your Way To Your PSU
A PSU, also known as Power Supply Unit, is a small box that converts the main power source into a suitable voltage before feeding it to other PC components.
If the component is damaged, it cannot send the right voltage for your display.
It could cause your display to blink, turn off or even go dark for a short period.
It has nothing to do with your battery and could occur even if you’re attached to the wall.
Take out the component, and then start your PC with no piece.
If the issue is not apparent, check that your PSU fans are running smoothly and that they aren’t overheating.
Check the physical appearance of the item for signs of corrosion, cracks, etc.
Replace the connected wires, and if the wires are still in good condition, Send the entire system to be repaired.
Experts may also recommend buying a brand new PSU. Be prepared to deal with that possibility.
Look for Power Interference
The power supply issues aren’t just concerned with energy-saving settings or the powerful hardware that supplies power.
They can be caused by external factors, for example, a power failure home and local wiring, etc.
Use the tracking device for power interruptions, or contact your local power provider to determine if there’s an electrical problem in your community.
You can also utilize a UPS to determine whether the issue is still present with your emergency power.
The device can keep the connection at an acceptable voltage and is not a victim of interruptions or malfunctions.
It is easy to rule out the possibility of interference with the power out if you are still experiencing the same problem.
Another option is to switch off the lighting and kitchen appliances, and other appliances that use energy to see whether the black screen is showing up randomly.
Make sure you check your GPU.
The GPU (graphics processing unit) is a special computer chip used to accelerate the production and display of images.
It’s not jolting me to check whether it’s causing issues with the display. It could be that it has been unable to function because of long-term usage, or it may have become disconnected from your monitor.
You must first disengage this circuit from your system to confirm that it’s the primary cause.
- Enter ” Device Manager” in the Windows search bar and launch the application.
- Extend your search to the ” Display adapters” category to find the name of your GPU from there.
- Right-click and select ” Disable device.“
- Restart your PC and use it for a couple of minutes to determine whether the issue continues. If it appears to resolve the issue, you can try the next step to identify the problem with your graphics card.
- Cool It Down
Install and download monitoring software, like HWmonitor, Open Hardware Monitor, or SpeedFan to monitor your GPU temperatures and the speed of your fan.
If they appear to be below the threshold:
- Vacuum out the dust inside the fan and clean the fan.
- Include an additional cooling system.
- Replace the paste that was used for heating.
- Bring your GPU into the repair facility.
- Purchase a brand new piece.
You are overclocking your device forces it to render multimedia files more quickly than the standard.
Although it is designed to increase performance, this can harm your experience on the screen and can have a negative impact.
Use the same tools described above to find the GPU primary clock.
If you find that it’s not perfect, you can disable the overclocking feature on your computer.
Here’s a second guide to help you examine your GPU for issues.
Make use of a third-party assistant.
Outward repair tools are your best friend in the event of repairing a system-specific issue.
They can locate and remove duplicate files, fix damaged registry entries, remove annoying bugs, and add new life to your computer.
Make sure you find a trustworthy platform that doesn’t cause problems instead of finding the solution.
This is because these settings are extremely sensitive, and if they are not altered sensibly, it could make your computer unusable.
