The joy of a person who has become the owner of a new personal computer in most cases has no limit. Indeed, the brand new shiny plastic, flashing lights, the highest technical specifications that allow you to instantly perform almost any task and many other joyful moments brought by the purchase, rarely leave anyone indifferent. At the same time, time passes and the joy fades, and sometimes develops into annoyance, especially when PC malfunctions, freezes, reboots and spontaneous shutdown for no apparent reason. All this does not allow you to work and have fun and turns the use of a computer into real flour. Below, an attempt will be made to understand why the computer itself shuts down, why the computer freezes, and also reboots itself spontaneously.
In fact, users asking questions why the computer itself shuts down, why the computer freezes, 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 first. The cause of a sudden reboot or shutdown may be the consequences of computer viruses. To get rid of this trouble, you need to conduct a full PC scan for viruses through a reliable antivirus program with the latest databases. Sometimes it is advisable to use two antiviruses, due to the fact that the infection may not be detected by one of them, but it will definitely be noticed by the second. In some cases, this approach does not allow you to get rid of the problem - then only the formatting of the hard disk and, accordingly, reinstalling the operating system remains. If in this case too, the question of why the computer turns off itself remains open, that is, the problem continues to appear, the reason must be sought in another - the hardware. By the way, due to the repetition of spontaneous shutdowns due to hardware problems, attempts to install the OS on a formatted disk or formatting itself may fail.
The second one. 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 of why the computer itself shuts down, you need to remember when the device was last serviced, that is, cleaned. The fact is that PC components that are prone to heat are cooled by fans that blow air from the outside. In any room where the computer is installed, there is dust that enters the system unit along with the air drawn in, where it settles on the components, reducing heat dissipation, which over time causes the components to overheat. Thus, experts recommend cleaning the system unit from 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, PC freezes and reboots. Cleaning can be carried out both by service center specialists and independently - the procedure is not as complicated as it might seem at first glance - to carry it out you need only a soft brush, a vacuum cleaner and accuracy.
The third. CPU overheating . This component in the event of freezes and sudden reboots should be highlighted. The fact is that overheating of the central processor can be caused not only by dust deposited on the blades of its fan and radiator, but also by dried or improperly applied thermal grease - a special mixture that provides heat exchange between the processor case and the cooling radiator. If processor overheating is detected , then the first thing to do is replace the thermal paste!
