The black screen is one of the classic computer operating problems. If your PC is black-screened when you switch it on and you don't know what to do.
Don't panic, in our article we'll show you how to solve this black screen problem on Windows. However, before we look at the latter, let's first see why your computer's screen remains black when you turn it on. What are the solutions to this black screen problem on startup?
When I turn on my PC, the screen stays black?
There are several possible reasons for a black screen at startup. It may be that your computer's graphics card has broken down, or that the connector on your motherboard is no longer working. The latter happens when your motherboard is old or has a power surge problem. You should also check that you have a dedicated graphics card and not integrated graphics.
Also check that your screen isn't the problem. For example, you can test your screen cable with your TV. If it works on another device, your PC screen is no longer working or is defective. However, it's also possible that your computer is suffering from a power surge, and this is not necessarily a hardware failure. In these cases, simply switch off your computer and restart it again.
Detect the source of the problem
Before starting to solve your computer's black screen problem, it's important to diagnose the source of the problem. Check that your screen is switched on and that the LED lights up when you press the power button.
If it doesn't light up, there's a wiring problem and the current isn't flowing. You can, for example, test another cable to see if it's the cable that's damaged.
It may also happen that when you switch on your PC, the LED lights up, but the screen doesn't display anything. In this case, you'll need to interpret the various noises made by your computer to detect the problem.
It may be that one of its components is missing, and you'll need to replace it to get it working normally. However, if the light is off, either the plug doesn't work and you'll need to find another socket to plug the computer into, or it's your screen that's faulty and needs to be repaired or replaced.

Before solving the problem too, check that your screen is switched on and that the cables are connected. Sometimes, the screen may not work due to a simple oversight. You can also reconnect your computer and its screen. You can force the shutdown by combining Ctrl + Alt + Delete to make the black screen disappear on Windows.
