What to do if the monitor does not turn on when you turn on the computer

A computer is a rather complex device, which consists of many different parts. At the same time it installs specialized programs on which its operation depends. That's why when there is a certain breakdown, it must be considered in the whole device, rather than evaluate one part.

For example, if the monitor does not turn on when the computer is turned on, there may be many reasons for this, and they may not even be connected to the monitor itself. Therefore, in order to determine the real cause of the failure, it is necessary to perform a certain sequence of actions, as a result of which a breakdown will be detected.

First of all, if the monitor does not turn on when you turn on the computer , you need to check whether the power cord of its power outlet is connected to the outlet. At the same time, make sure that the socket itself is also energized.

If everything is in order and the problem is not fixed, then it is necessary to check the connection of the computer to the monitor itself and, in addition, the correctness and quality of the wire connection.

If all of the above steps are performed, and when you turn on the computer does not turn on the monitor, then you need to check the monitor itself. To do this, you need to make sure that the power button is turned on, and if there are no changes, you should connect the monitor to another computer. Thus, it is possible to detect its breakdown.

If the device proved to be working, and when you turn on the computer does not turn on the monitor, you need to check the video card. On modern system blocks, this is quite simple. It is necessary to switch the video cord from the video card connector to the built-in video connector of the motherboard. If the monitor works, then the fault is in it. However, if there is no integrated graphics card on the system unit, you can rearrange the main board to another computer for verification.

If all the actions were performed correctly, and when the computer is turned on the monitor does not turn on, there is a high probability that the malfunction is in the motherboard or power supply.

To check the motherboard, it is necessary after touching the power switch to touch some of the microcircuits to check for elevated temperature. If an overheating element was found in such a survey, then the problem is in the motherboard. If no such part is found, then you can check the power supply. Usually the reason is that there is no power supply to the cooling fans.

When all the above actions are performed, and the monitor does not turn on when you turn on the computer, the last thing you can do at home is to clean the system unit from dust. It is a good conductor and can cause a short circuit, especially on old or damaged cards.
If during the process of performing this check a nonworking part was found or the cause of the failure was not found, you should contact the service center where the computer will be inspected on a special stand, and the nonworking part will be replaced.
