The one thing that every computer user dreads is what is known as a Black Screen of Death. The biggest problem with this situation is that there is no error message that accompanies it so you are left in the dark when it comes to understanding the reason why your screen may be dark. Even though it is difficult to guess where the problem may be emanating from, experience has shown that some things are more likely to cause the problem than others. The leading culprits are errors in software, faulty connections or errors in the display, issues with power supply, and overheating.  

Power Supply

While the computer’s power supply is probably one of the easiest things to solve when it comes to a dark screen, it is often overlooked. Without power, the PC is unable to run. It is obvious that when there is no power, the screen of your PC will suddenly go off. This may be a different case when it comes to a laptop as the battery may last for some time even when there is no power coming from an external source. Sometimes if the PSU is faulty, it may power certain components and leave others without access to power.

Errors with Software

Sometimes your back screen could be a result of software with a fault. You will need to watch for this especially when you are dealing with programs that have the tendency to take over the whole screen. The black screen may be a result of locking up due to inability to display something. This can lead you to lose control of the PC. When this is the case, your computer may continue to do other tasks such as producing sound even when the screen is black.

Error with The Display

The error on a video can leave your screen dark. The black screen will just be a result of lack of video output. Before you panic, you may want to look carefully to ensure that the connection is not faulty. Check that there are no damages on the codes, the HDMI and DVI cords are secure, and the display cable is also sitting firmly in its slot. If the monitor has just had an upgrade, you may also want to review the resolution to ensure that it is right for your connection to handle.


Another big culprit behind a black screen is overheating. Since too much heat can be dangerous for your computer, it is designed to shut itself down if overheating is occurring anywhere in the system. This type of black screen is sometimes followed by a restart when the computer has cooled but this is not guaranteed.

As you can see, the problems that could lead to a black screen come from varied sources and can waste a lot of your time as you attempt to understand where they come from. This is the reason why resorting to tried and tested systems such as DriverAssist can help to keep your system and its drivers functioning at their best. The system takes away the need to keep trying to figure out where problems such as the black screen are coming from by doing a regular scan of your system. This identifies problems before they occur.
