Is your PC monitor turning black randomly?
Lately, some Windows users have complained that their computer screen keeps turning black, mostly while playing games or doing graphics-intensive work.
If you are having the same issue, follow this guide. Here are the reasons for the issue and the solutions to fix the problem.
Why Does My Monitor Keep Going Black?
The computer monitor can turn black due to the following reasons:
- Loose Connection of the HDMI cable
- Bad Power Supply Unit or PSU
- Outdated OS
- Third-party applications

What To Do If Monitor Keeps Going Black?
Here are the working solutions to fix the PC screen when it is randomly turning black.
1) Check The HDMI Cable
If the HDMI cable is not properly connected, the monitor can go black.
Make sure to connect it properly. Also, Check the HDMI cable for any physical damage.
You can change the HDMI cable and try another cable to check if everything is working properly.
There can be a problem with the HDMI port you are using. So, change the port and see if it is working.
If you use an HDMI to VGA converter, use a pure HDMI cable instead.
This will help you to check if the HDMI module on both the input and output is working properly.
2) Check The Main Power
If there is no power supply, you cannot turn on your PC monitor.
So, check the main power outlet. You can try connecting your PC to some other source and check if the monitor is turning on.
You can disconnect all the cables attached to the back of the monitor and reconnect them tightly.
If there is any power interference, the monitor can also go lacking. Observe the monitor while turning on a light or some other electrical appliance.
If you see the monitor fluctuates, this means that the wiring is not proper.
You can use a UPS to regularize the voltage to fix the problem. If this does not fix the issue, check your PSU.
3) Check The PSU
The power Supply Unit or PSU takes the AC power from the main electric outlet and transmits the voltage you’re your PC.
If the PSU is damaged and not transmitting the power correctly, the computer screen can go black.
To check if this is happening from the PSU, you can try another PSU. Also, ensure that the cable that is connecting the PSU to the main electric outlet is not damaged.
Once checking all these, if the problem persists, check the GPU.
4) Check The GPU
If you have installed any third-party GPU like NVIDIA or AMD, and it is not working properly, the monitor can also keep turning black.
