What to do if the computer turns off

If the computer turns off by itself, it's not an excuse to run to the nearest computer store and buy a new one. Sometimes the reason for this abnormal behavior is trivial enough and can be easily eliminated even without visiting the service centers. In today's article, we'll talk about why the computer shuts down and how the user can help his electronic assistant on his own.

Since the reasons for switching off the power supply are different, their manifestation also differs. This makes it possible to determine with high probability why the computer turns off. Although, of course, for a reliable diagnosis it is necessary to see the electronic device itself.

If the computer itself turns off, the reasons can be as follows:

- exceeding the permissible temperature of the CPU and / or video adapter;

- mismatch of mains voltage with the adopted standards;

- damage to the power supply unit;

- malfunction of components.

Some components of the system unit are very hot during operation and require active cooling to remove heat. For this, radiators with fans are installed on the central processor and a chip of a discrete video card . Gradually, the dust settles on the fins of the radiators, which worsens the heat transfer, which leads to a decrease Cooling system efficiency. Sometimes the situation is aggravated by the ingress of dust into the bearing of the fan, which jams it. The result is that the computer turns off after a few minutes. And the disconnection will occur sooner, the higher the computing load. In other words, if the system unit spontaneously shuts down after a while, you need to check the condition of the cooling systems (whether the fan is spinning), clean them. Sometimes the simple removal of the housing cover or the removal of the system unit from the radiators helps. During operation it is necessary to control the temperature of the components. To do this, you can use the programs SiSoft Sandra, AIDA64 or HMonitor. Heating should not exceed 60-70 degrees (depending on the model).

Often, the computer turns off because of an overestimated or underestimated mains voltage. To check, you will need a voltmeter with the appropriate measurement limits. The home socket should be 200 to 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 have insufficient quality, therefore, they do not work more than 1-2 years, after which their replacement is necessary. Alas, very few people follow this rule, but in vain! Believe me, the amount spent on replacing a burnt motherboard and processor is much higher than the cost of a new budgetary power supply.

Of course, you can not ignore the damage components. For example, any electronic components have their own lifetime, after which the manufacturer disclaims all warranty obligations. The realities of our country are such that the owners of computers exploit them "to the last." You can advise periodically to look into the case of the system unit, clean it from dust, check the status of components.

So, the answer to the question of what to do if the computer itself turns off, is to thoroughly check the status of all components and their revision. If nothing helps, then it may be necessary to replace the failed component.
