Why does the computer turn off on its own? Repair, computer setup

Many now can not imagine their lives without the daily use of a computer. 10 years ago it was a luxury, today there is practically a PC or a laptop for everyone. We are increasingly becoming dependent on such equipment. Monthly reports, photos dear to the heart, personal documents and much more - all this is stored today not on paper, but on the PC hard drive. Let's talk about typical problems, in particular about why the computer turns off on its own.

Some general information

A computer is an expensive and very complex electronic equipment that requires periodic maintenance and proper operation. To say that the computer does not work correctly or unstable, without observing elementary rules, it is not necessary at all.

You're probably wondering why the computer turns itself off ? To give an unambiguous answer to this question, it is necessary to go through a large number of options than we, in fact, will deal with in this article. But before that I would like to note that any computer or laptop, regardless of age or technical condition, should be modernized from time to time. It happens that the technology has simply worked its way, the resource of the mother card or other important component has been exhausted, and so failures occur. But now we will try to understand more specifically why the computer is turned off by itself, how to fix it, and whether it is possible at all. But first things first.

Excessive dustiness

Probably, in the workshops for computer repair specialists have long ceased to be surprised at the amount of dust that can settle in the system unit. Nevertheless, it can make an unforgettable impression on you. If you purchased your PC more than a year ago and never opened its lid for curiosity, then do it. Of course, if the equipment is still under warranty, then this should not be done, since the obligations signed in the contract will be violated. And if suddenly the system block fails because of you, and the seals are already torn off, you'll have to repair it for your own money.

So, what do you do if the computer turns off, you ask? Open the cover of the system unit and see if there is dust. Excessive amount of it can contribute to overheating of key nodes (video card, processor), etc. As a result, the protection is activated and the PC turns off. In any case, it is not a problem to blow out dust with the most common vacuum cleaner. True, it is necessary to be extremely cautious and to de-energize the equipment.

Problems with the operating system

Before you climb under the cover of the system unit, you need to understand your own operating system. If all the problems started after the reinstallation of "Winds", then it is obvious that the reason is exactly this. In addition, the case may be associated with a malicious program that has been accessed to you through the Internet or a memory card. Changing the source code of the operating system files will lead to errors. The system will try to fix them by rebooting. Therefore, first of all install the antivirus program.

Another important point is that not all assemblies, in particular pirate ones, work stably. This is obvious, so if possible try to install a licensed OS, well, or a "clean" pirate. Try to install another OS, if the problem does not resolve, then you need to look elsewhere. Of course, we need to start from the simplest, we'll talk about this.

The thermal paste has dried up

Generally, quite often any breakdown on the PC is due to overheating of the main working nodes. A dry thermal paste is one of the main reasons for the very excessive, critical heating. Modern computers are reliably protected from heat. If the temperature reaches a critical maximum, the PC turns off. It will turn on in 5-15 minutes, that is, when the node has cooled down. But the PC will turn on and after a couple of minutes it will turn off again, and it will be repeated indefinitely.

The reason can be very trite - the drying of the thermal paste. What is thermal paste, you ask? The so-called thermal interface is necessary for efficient heat removal from the working area. This is a viscous substance that helps cool the processor, video card and all those places where there are coolers. So, computer repair will be required exactly when the paste dries. It must be changed at least once every few years, at least so it is recommended to do so.

The computer shuts down during operation: causes and solutions

As noted, the problem often lies in too high a temperature. The processor in this case is the most vulnerable place. The fact is that during work it is heated very much, therefore this node is extremely dependent on the effective operation of the cooler. Often the problem lies in the following. You overclocked the processor and increased its power, say, by 10%. The fan rotates at the same speed. This will inevitably lead to overheating of the processor and, possibly, its failure. Nevertheless, if the acceleration is carried out correctly, according to the instructions, then problems are unlikely to arise.

The repair of computers after the processor out of order is quick, but very expensive. A powerful CPU will cost you a significant amount of money. Determine whether the processor is a weak link is very simple. For this you can download a program that controls its temperature. If it reaches the upper limit, you will definitely notice it. It will only take appropriate measures.

About the power supply

The situation when the power supply unit is the culprit of a sudden shutdown is relatively small, but they do occur. Most often this happens because of its insufficient power. For example, you bought a system unit, and then changed the graphics card and processor to more powerful analogs. At the same time, the power supply unit (PSU) remained standard. While increasing the load on it, say, at the start of any demanding game, it may simply not provide enough power to "stuff" your system unit and shut down.

If the computer turns off when you turn it on, things are completely bad. Most likely, you will need to replace the power supply with a more powerful one. By the way, this parameter must also be calculated in order not to spend too much. The more powerful the system unit as a whole, the more efficient the PSU must be. By the way, look at its cooling, perhaps there is too much dust.

Shutdown due to video card and RAM

If the computer is turned off during the game, then most likely we are faced with any failure of the video card. The problem may be that the cooler can not cope, as a result, the temperature rises and protection works. If you performed overclocking the video card, then return all to the factory settings and, probably, the problem will disappear.

As for RAM, it is better to start diagnostics. If you notice periodic system hangs, brakes, incorrect playback of video files and games, then the case may be in RAM. You can check it under load using AIDA 32/64.

Motherboard

This is the most expensive and important element of the system unit. It is on the motherboard that the whole system is held. If the computer shuts down during bootup, this may be a signal that it's time to check the "mother". If capacitors are out of order, then they can be soldered. If there are microcracks in the soldering, then there is a possibility that they will be filled with dust, and everything will fall into place. Otherwise, you have to change the board.

There is still such a crucial element as the chipset, it is on the motherboard and is cooled by a small metal cooler. So, it often overheats, because of what OS and reboots. Check it with a multimeter and change the cooler if necessary.

I / O device is turned off

Often there are problems with periodic disconnection of the keyboard, mouse, webcam and other peripherals. Fortunately, most of these ailments are simply and quickly eliminated. Something is treated by installing the latest drivers. If this does not help, then the case may be in the port to which the device is connected. If the keyboard is disabled on the computer, check the driver's urgency, the port's working capacity. If it does not help, take the keyboard to the repair shop, perhaps it's in it.

It happens that the sound on the computer suddenly went off. In this case it makes sense to check the same port, and then the wire going to the column. It is possible that you have a sound driver, in this case, no sounds on the PC will not be played. A fresh driver can be downloaded from the official website of the manufacturer.

How to set up your computer correctly

The correct configuration of the system plays an important role . Here we mean different BIOS settings, in particular, it is not recommended to overclock the PC. If you do this, then soberly assess all the risks. In too weak personal computers, overclocking will not give any performance gain. It is advisable to always use the factory settings and frequencies, which will guarantee a long and trouble-free operation. For example, if the computer monitor turns off during operation, this may indicate a gradual failure of the matrix. It will be easier for you to buy a new display, rather than repairing an old one. From you, this failure does not depend much, but everything that is in the system block is better left as it is.

Conclusion

As you can see, quite a lot of reasons why the computer turns off on its own. To quickly deal with the problem, it is recommended to use monitoring programs. So you can control the temperature of all components. If necessary, you can run the test under load, which will show what exactly is causing the failure, and why the PC is turned off. As for the repair, it is unlikely that you can qualitatively solder the capacitors of the motherboard, but here is to replace the thermal paste or perform a blow from the dust under the power of everyone. To work the computer for a long time, it is necessary to ensure a stable voltage. To do this, use voltage regulators, and you will be happy.
