If your computer suddenly goes black, the first thing to check is whether the computer is set to enter sleep mode, which turns off the monitor.  It could be a problem with the hardware, or it could be a problem with the software. It could also be a problem with the internal wiring of the monitor or a problem with something connected to the monitor.

Why does my monitor keep turning off when my PC is still on?

This is a problem in which the display randomly turns off and on. The display can be on for a few seconds to several minutes, then turned back off.  There are many possible reasons for this. Some include:

Screen issues – One of the most common problems is something wrong with the screen itself. If you notice that your screen turns off when it gets hot, then there’s likely an issue with the cooling system in your computer. It, therefore, shuts down to minimize the risk of damage. Faulty power switch – Your monitor may turn off randomly because of a faulty power switch on the back of the monitor. In your computer’s case, the power supply unit could be failing to send enough power to the monitor, causing it to shut off. Loose connection – Another possible reason why your computer monitor randomly turns off could be due to a loose connection between the computer and the monitor. Faulty GPU – If your graphics card drivers are outdated, it can cause crashes, video playback and display issues, game performance problems, and other related issues.

Fixing this problem is not as difficult as you might think. You can often use simple troubleshooting steps to determine why your computer monitor randomly turns off and fix it.
