Why does my computer shut down? This question is asked by many people who are faced with this. There are a lot of problems that can cause this behavior of your iron friend. Consider the main ones.
First of all, if your computer suddenly shuts down, do not panic. But since you are reading this article, it means that you found the opportunity to go to the network from another device and probably already calmed down. You need to understand the reason why the computer is turned off.
If it shuts down shortly after a successful boot, check the power button. Yes, do not laugh, because if it is stuck, then it, accordingly, sends a signal to turn off soon after activation, and the computer turns off. Many people come to the service center with this problem, and they are helped in a few minutes, but they take money for it. But you yourself can cope with this minor malfunction: just pick up the button and return it to its original position.
If this does not help, check the computer's system unit. Do not be afraid to do this, but first disconnect the wires. The current will not hit you, since the voltage inside the unit is minimal and with the power wire connected, however you can accidentally pull it out with the socket, which you absolutely do not need. Unscrewing the bolts holding the cover of the system, evaluate the status of computer components visually. If the capacitors are not swollen, there are no signs of thermal damage on the printed circuit boards and other elements, so the device is not damaged at the physical level.
By the way, until you close the system unit, check whether you have long cleaned the cooling system. This can give an answer to the question of why the computer is turned off. If you ignore this necessary maintenance for too long, a lot of dust will accumulate in the system unit, which will hinder the flow of cold air to the device. Consequently, it will turn off from overheating. Look at the big cooler in the center of the motherboard. It cools the processor. If it is too clogged with dust, clean it. This can help a vacuum cleaner, although it is better to carry out a more thorough cleaning yourself, for example with cotton buds.
By the way, the reason why a computer turns off can be a completely trivial thing. In the house they can simply turn off the electricity, your cat or dog gnawed the wire, the grandmother overdid it and pulled the plug out of the socket, wiping the plinth.
If you are not interested in the question of why the computer is turned off and you are the owner of the laptop, then the cause is most likely one. Since in this device the cooling system is in even more unfavorable conditions, it is very easily clogged with dust. To clean it, you need to take the laptop to a service center where dirt is removed for a small fee. Of course, you can do it yourself if you have the necessary skills. It is enough to understand in which places it is necessary to unscrew the bolts of the laptop to remove the lid and gain access to the cherished cooling system. However, some devices are made in such a way that it requires disassembling the entire enclosure, and this is only possible for specialists.
