Why does the computer turn itself off? The three most common reasons.

The joy of a person who has become the owner of a new personal computer in most cases there is no limit. Indeed, brand new shiny plastic, flashing light bulbs, the highest technical characteristics that allow you to perform almost any task instantly and many other joyful moments brought by buying, rarely leave anyone indifferent. At the same time, time passes and joy fades, and sometimes grows into an annoyance, especially when there are malfunctions in the PC, hang-ups, reboots and spontaneous shutdown for no apparent reason. All this does not allow you to work and play normally and turns your computer's use into real flour. Below, an attempt will be made to understand why the computer itself turns off, why the computer hangs up, and also spontaneously reboots.

In fact, users asking questions, why the computer turns itself off, why the computer is hanging, should understand that there can be many reasons for such phenomena due to the complexity of modern technology. We will focus on the most common of them.

So the first. The cause of a sudden reboot or shutdown may be the effects of computer virus actions . To get rid of this trouble it is necessary to conduct a full scan of the PC for viruses by means of a reliable anti-virus program with the latest databases. Sometimes it is advisable to use two antiviruses, in view of the fact that infection can not be detected by one of them, but it will be accurately noticed by the second. In some cases, this approach also does not allow to get rid of the problem - then only the formatting of the hard disk remains and, accordingly, the reinstallation of the operating system. If in this case the question of why the computer itself is turned off remains open, that is, the problem continues to appear, the reason must be sought in the other - the hardware part. By the way, in view of the repetition of spontaneous shutdowns due to hardware problems, attempts to install the OS on a formatted disk or formatting itself can fail.

The second. Perhaps the main reason for the spontaneous shutdown of a personal computer is the overheating of the components from which it is assembled. In this aspect, before answering the question why the computer itself turns off, it is necessary to remember when the device was last subjected to maintenance, that is, cleaning. The fact is that PC components prone to heating are cooled by means of fans that pump air from outside. In any room where the computer is installed, there is dust that gets inside the system unit along with the drawn-in air, where it settles on the components, reducing the heat sink, which over time causes overheating of the components. Thus, experts recommend that the system unit be cleaned of dust with a frequency of at least once a year. In most cases, this ensures that there is no possibility of overheating of the components and, as a consequence, hangs of the PC and reboots. Cleaning can be carried out both by specialists of service centers, and independently - the procedure is not as complicated as it might seem at first glance - for its carrying out only a soft brush, vacuum cleaner and accuracy are needed.

Third. Overheating of the CPU. This component in the case of hibernation and sudden reboot should be highlighted. The fact is that the CPU can overheat not only the dust that has settled on the blades of its fan and radiator, but also the dried or improperly applied thermal paste - a special mixture that provides heat exchange between the processor body and the cooling radiator. If the CPU overheating is detected, the first thing to do is replace the thermal paste!
