Why computer turns off by itself? Repair, computer setup

Many people now cannot imagine their lives without daily computer use. 10 years ago it was a luxury, today PC or laptop is almost everyone. We are increasingly becoming dependent on such equipment. Monthly reports, great photos, personal documents, and more – all this today is stored not on paper but on the PC's hard drive. Let's talk about the typical issues, in particular on why the computer turns off by itself.

General information

Computer – it's expensive and very sophisticated electronic equipment that requires periodic maintenance and proper operation. To say that the computer incorrectly or becomes unstable, not respecting basic rules, generally do not need.

You probably wonder why computer turns off by itself? To give a definite answer to this question, you must iterate through a large number of options, what we are actually going to do in this article. But before that I would like to note that any computer or laptop, regardless of age or condition, should from time to time to modernize. It so happens that the technology simply worked, consumed resource parent card or other important component, that is causing the problems. But now we will try to more specifically deal with why computer turns off by itself how to fix it, and if it's even possible. But about all under the order.

Excessive amounts of dust

Probably in the workshops of the computer repair specialists has long ceased to be surprised by the amount of dust that can settle in the system unit. Nevertheless, you is able to make a first impression. If you bought your PC a year ago and never opened the cover for the sake of curiosity, then do so. Of course, if your appliances are still under warranty, you should not do this because they violated the commitments in the contract. And if the system unit will be damaged not because of you, and the seal is already broken, will have to be repaired with his own money.

So, what to do if computer turns off, you ask? Open the cover of the system unit and see if there's dust. Excessive amount of it can contribute to overheating of key components (video card, processor) and for fire protection and the PC shuts down. In any case, to carry out the blowing of dust using an ordinary vacuum cleaner can not hurt. However, you must be extremely careful and pre-disconnect equipment.

Problems with the operating system

Before you climb under the cover of the system unit, you need to deal with their own operating system. If all the problems started after reinstalling “Windows”, it is obvious that this is the reason. In addition, it might be related to a malicious program that via Internet or memory card gets to you. Change the source code of the operating system files will cause errors. The system will try to correct it by rebooting. So first of all install the antivirus program.

Another important point is that not all of the Assembly, in particular the pirate working. So if possible, try to install a licensed operating system, well, or “clean” pirates. Try to install another OS, if the problem is not solved, it is necessary to look elsewhere. Of course, you need to start with the basics, we'll talk.

Dried up thermal grease

Actually, quite often any failure on the PC connected with the overheating of the major job sites. Dried thermal paste – one of the main reasons for the excessive, critical heat. Modern computers are protected from the heat. If the temperature reaches a critical maximum, the PC turns off. It will turn on minutes 5-15, that is, when the site has cooled. But the PC turns on and after a couple of minutes will turn off again, and it will be repeated indefinitely.

The Cause may be very trivial – drying of thermal paste. What is thermal paste, you ask? The so-called thermal interface is necessary for effective heat removal from the working area. Cholesterol is a waxy substance that contributes to the cooling of the CPU, graphics card and all those places where there are coolers. So, computer repair services, you will need exactly when pasta was dry. It should be changed at least every few years, at least as recommended.

Computer turns off during operation: causes and Troubleshooting

As noted, often the problem is too high temperature. The processor in this case is the most vulnerable place. The fact that during work he is very hot, so this node is very dependent on the efficient operation of the cooler. Often, the problem lies in the following. You have carried out the overclocking and increased its capacity by, say, 10%. The fan is spinning at the same speed. This will inevitably lead to the CPU overheating and possible failure. However, ifto overclock properly according to the manual, the problem is unlikely to arise.

Repair of computers after the CPU down is fast, but very expensive. A powerful CPU will cost you a considerable amount of money. To determine whether the processor is the weak link, very simple. For this you can download a program that controls its temperature. If it will reach an upper limit, you will definitely notice. Will only accept the appropriate actions.

Power supply

Situations where the power supply acts as a culprit for the sudden disconnection, is relatively small, but they do occur. Most often it happens because of his lack of power. For example, you bought a system unit, and then changed the graphics card and the processor on more powerful counterparts. At the same time, the power supply unit (PSU) remains the standard. During increase of load on it, say, when you run any demanding games, it may just not provide enough power “stuffing” your system unit on and off.

If the computer shuts off when turned on, things really bad. Most likely need to replace the power unit on more powerful. By the way, this option should also expect not to spend too much. The more powerful the system unit as a whole, the more productive must be the PSU. By the way, look and for its cooling, maybe there's too much dust.

Off because of the video card and RAM

If during a game the computer turns off, then most likely we are faced with any failure of the graphics card. The problem may lie in the fact that the cooler is unable to cope, as a consequence, the temperature rises and triggered protection. If you were overclocking, return all to factory settings and maybe the problem will disappear.

As for the RAM, then it is better to start diagnostics. If you noticed periodic freezes of the system, the brakes, or incorrect video playback and games, the case can be in the RAM. Check it under load, you can use the program AIDA 32/64.

Motherboard

This is the most expensive and important element of the system unit. It is on the motherboard and the whole system. If when booting the computer turns off, then it may be a signal that it's time to check ‘mother”. If down came the capacitor, you can resolder. If soldering is formed microcracks, that is, the probability that they will be filled with dust, and all will fall into place. Otherwise, you will have to change the cost.

There is still such a crucial element of the chipset, it is on the motherboard and is cooled by a small metal cooler. So, he often overheats, causing the OS and rebooted. Check it with a multimeter and if necessary, adjust the cooler.

Turn Off the device I/o

Often have problems with periodic off keyboards, mice, Webcams and other peripheral devices. Fortunately, most of these diseases simply and quickly eliminated. Something cured by installing the latest drivers. If that doesn't work, then it may be the port to which the device is connected. If off, the keyboard on the computer, check the relevance of the driver, the operability of the port. If all else fails, take the keyboard to check in the workshop, maybe it is there.

It so Happens that suddenly turn off the sound on the computer. In this case it makes sense to test the same port, and then wire going to the column. It is quite possible that you flew the sound driver, in this case, no sound on PC cannot be played. The latest driver can be downloaded on the official website of the manufacturer.

How to configure the computer

The Important role played by proper configuration of the system. Here refers to the various settings of the BIOS, in particular, it is not recommended to overclock a PC. If you are doing this, and then assess all risks. Too weak in personal computers, overclocking will not give any performance boost. It is advisable to always use the factory settings, and frequency that will guarantee a long and trouble-free operation. For example, if computer monitor turns off during operation, this may indicate a gradual breakdown of the matrix. You will be able to buy a new display than to repair the old. From you this failure is little affected, but all that is in the system unit, it is better to leave the way it is.

Conclusion

As you can see, reasons why computer turns off by itself, pretty much. 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 perform a test under load, which will show what exactly fails, and why the PC shuts down. As for the repair, it is unlikely that you will be able to resolder the capacitors of the motherboard, but to replace the thermal paste, or purge dust under the force. The computer worked for a long time, it is necessary to provide a stable voltage. To do this, use surge protectors, and you will behappiness.
