Computers have become an important and inevitable tool in people’s lives, because with them they work, study and communicate with their loved ones, but also, malfunctions of these devices have become common in everyday life. For example, with Desktop computers, sometimes the screen goes black or immediately into hibernation.

This is because The monitor is not receiving a signal from the CPUAnd while in some cases the only thing that can be done is to take the computer to a technician, it’s always a good idea to solve the problem yourself first.

Without a doubt, the technical failure that can cause the most confusion and irritation is that The screen does not turn onBecause that’s how you have access to all the features of the equipment, and if it doesn’t represent a picture, it’s impossible to know what happened, and although this type of inconvenience is related to the hardware and connection points, Some users have experienced this after updating their operating system. These are some actions that can be done before going to the repair center.

When checking the image again lost. This is because the faulty cable may not be from the monitor, but from another element that is causing the shorted cable.
