Why does the computer turn off? This question is asked by many people who have encountered this. There are many problems that can cause this behavior of your iron friend. Consider the main ones.
First of all, if your computer shuts down suddenly, you should not panic. But since you are reading this article, you have found the opportunity to access the network from another device and have probably calmed down. You need to understand the reason why the computer turns off.
If it turns off 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 shortly 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 problem: just pick up the button and return it to its original position.
If this check does not help, look at the system unit of the computer. Do not be afraid to do this, but first disconnect the wires. You won’t be shocked, because the voltage inside the unit is minimal even when the power cord is connected, but you can accidentally pull it out with the socket, and you don’t need it at all. Having unscrewed the bolts holding the system unit cover, assess the condition of the computer components visually. If the capacitors are not swollen, there are no traces of thermal damage on the printed circuit boards and other elements, which means that the device is not damaged on a physical level.
By the way, before you close the
system unit, check whether you have been cleaning the cooling system for a long time. This may provide an answer to the question of why the computer shuts down. If you ignore this necessary service for too long, a lot of dust will accumulate in the system unit, which will impede the flow of cold air to the device. Therefore, it will turn off from overheating. Look at the large cooler in the center of the motherboard. It cools the processor. If it is too clogged with dust, clean it. A vacuum cleaner can help with this, although a more thorough cleaning is best done independently, for example with cotton buds.
Incidentally, the reason why the computer shuts down can be a completely trivial thing. The house can simply turn off the electricity, your cat or dog gnawed the wire, your grandmother overdid it and pulled the plug from the outlet, wiping the baseboard.
If you are not interested in the question of why the computer turns off, and you are the owner of a laptop, then the reason is most likely one. Since in such a device
the cooling system is in even more adverse conditions, it is very easily clogged with dust. To clean it, you need to take the laptop to a service center, where dirt will be removed for a small fee. Of course, you can do it yourself, if you have the necessary skills. It is enough to understand in what places you need to unscrew the laptop bolts to remove the cover and gain access to the coveted cooling system. However, some devices are made in such a way that this requires disassembling the entire case, and only specialists can do it.
