If your computer shuts down by itself, it is not a reason to run to the nearest store to buy computer equipment and new.Sometimes the cause of the anomalous behavior rather trivial and easily eliminated, even without visiting the service center.In today's article we will focus on why the computer is turned off, and how the user can help your electronic assistant.
Since causes off, are different, and their expression is different.This allows a high probability to determine why the computer is turned off.Although, of course, for a reliable diagnosis is necessary to see the electronic device itself.
If the computer shuts itself, the reasons may be as follows:
- exceeding the permissible temperature of the CPU and / or video;
- mains voltage mismatch accepted norms;
- damage to the elements of the power supply;
- component failure.
Some components of the system unit become very hot during operation and need for heat dissipation active cooling.To do this on the CPU chip and a discrete graphics card installed radiators with fans.Gradually cooling fin dust settles worsening the heat, which reduces the efficiency of the cooling system.Sometimes the situation is aggravated by dust in the fan bearing that jammed it.The result - the computer is switched off after a few minutes of operation.Wherein the deactivation is rather higher than the computational load.In other words, if the system unit turns itself off after a while, you should check the status of the cooling systems (if the fan is spinning), clean them.Sometimes it helps to simply remove the body cap or move aside the system unit from the radiator.During operation, the temperature of the components must be controlled.You can use the software SiSoft Sandra, AIDA64 or HMonitor.Heat should not exceed 60-70 degrees (depending on model).
of the computer is switched off due to an excessive or insufficient supply voltage.To test the need voltmeter with relevant outside measurements.The home outlet should be from 200 to 240 volts.If this is not the case, the stabilizer must be purchased and to connect the computer to the network through it.
Many cheap power supply has insufficient quality, so do not regularly work more than 1-2 years, after which they need to be replaced.Alas, this rule should be very few people, but in vain!Believe me, the amount spent on the replacement of burnt motherboard and processor, much higher than the cost of a new budgetary power supply.
Of course, one can not ignore the damage to the components.For example, any electronic components have their lifespan, after which the manufacturer disclaims all warranties.The realities of our country is such that computer owners exploit them "to the last."You can consult periodically look into the case of the system unit, clean the dust, check the status of components.
So, the answer to the question of what to do if the computer itself is turned off, is thoroughly checked the status of all components and their revisions.If all else fails, you may need to replace the failed component.
