When you turn on your computer in Windows, nothing happens on the screen side, it's absolute black. Want to fix your PC and get rid of that black screen?

Here I am going to show you some tips to follow to know exactly what is the cause of the problem and how can it be solved?

To know the cause of the black screen of your PC, you have to know how the image arrives on the screen from the center unit.

The path begins with the motherboard which sends a signal to the graphics card, which itself sends a signal to the screen via a cable so that it displays images and / or characters.

However, if an element of the chain fails, the screen remains permanently black and nothing happens or a simple message tells you that the screen for lack of data will go back to deep standby.

Motherboard or graphics card, cable and screen: each element of the graphics chain has a role to play and when this does not happen as it should normally happen, then the screen remains in the initial state, i.e. that is, the slab does not display anything.

In general, a black screen appearing on a computer running Windows indicates a problem on your computer, the solution of which can be the following steps:

Changing the cable can help

The first thing to do when your screen remains black is to check that the various cables are properly powered. Check that the cable connecting the screen to the tower is properly connected.

If you have a screen with an HDMI connection, normally the cables are securely harnessed on both sides.

In the case of DVI or VGA connections, it is possible that the wires are just placed on the sockets without being screwed on the side of the screen or the graphics card. A simple movement of one or the other can be enough to lose the signal.


Changing the cable can also solve the problem.

Try to use another screen

If your screen still remains black despite changing the cable, the problem may be with your screen.

To remove any doubt, if you have another monitor or a compatible television set, you can plug it in instead of the one diagnosed as sick. Or you can plug your display into another central unit.

At best, you will be able to confirm that your screen is the disabled item.

Replace your graphics card

If the second screen remains black despite changing monitors, it may be because your graphics card is faulty.

Normally your computer should have signaled this to you with a series of beeps at startup, but this feature is unfortunately not always implemented.

If it is an additional graphics card, sometimes you just have to take it out of its PCI Express slot and clean the tracks with a soft cloth to make it work again. In the event that this does not change the situation, its replacement is mandatory to resolve your black screen problem.
