If the computer turns off by itself, then this is not a reason to run to the nearest computer store and buy a new one. Sometimes the reason for this abnormal behavior is quite trivial and can be easily eliminated even without visiting service centers. In today's article, we will discuss why the computer turns off, and how the user can independently help his electronic assistant.
Since the reasons for turning off the power are different, their manifestation is different. This makes it possible to determine why the computer is shutting down. Although, of course, for reliable diagnosis, you must see the electronic device itself.
If the computer itself shuts down, then the reasons may be as follows:
- excess of the permissible temperature of the central processor and / or video adapter;
- non-compliance of the mains voltage with the accepted standards;
- damage to the elements of the power supply;
- malfunction of components.
Some components of the system unit become very hot during operation and require active cooling to remove heat. To do this, radiators with fans are installed on the central processor and chip of the discrete video card . Gradually, dust settles on the fins of the radiators, worsening heat transfer, which leads to a decrease
Efficiency of the cooling system. Sometimes the situation is exacerbated by dust entering the fan bearing, which seizes it. Result - the computer turns off a few minutes after turning on. Moreover, the shutdown will occur the sooner the higher the computational load. In other words, if the
system unit spontaneously shuts down after a while, then you need to check the status of the cooling systems (does the fan spin), clean them. Sometimes it helps to simply remove the housing cover or move the system unit away from the radiators. During operation, you need to control the temperature of the components. You can use SiSoft Sandra, AIDA64 or HMonitor for this. Heating should not exceed 60-70 degrees (depending on model).
Often, the computer shuts down due to over or under voltage. To check, you need a voltmeter with the corresponding measurement limits. The home outlet should be between 200 and 240 volts. If this is not the case, you should purchase a stabilizer and connect the computer to the network through it.
Many inexpensive power supplies are of insufficient quality, so they work properly for no more than 1-2 years, after which their replacement is necessary. Alas, few people follow this rule, but in vain! Believe me, the amount spent on replacing a burned out motherboard and processor far exceeds the cost of a new budget power supply.
Of course, damage to components cannot be ignored. For example, any electronic elements have their own life, after which the manufacturer declines all warranty obligations. The realities of our country are such that the owners of computers exploit them "to the last." It is advisable to periodically look into the body of the system unit, clean it of dust, and check the condition of the components.
So, the answer to the question of what to do if the computer turns off itself consists in a thorough check of the status of all components and their revision. If all else fails, then you may need to replace the failed component.
