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.

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.

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.
