The computer turns on by itself: how to solve the problems associated with the inclusion

Computers are machines that deliver a lot of hassle to users. If the device works normally, then the gadget makes life much easier. But in the case of those or other failures, serious problems begin. Often, users complain that the computer turns on by itself. Or not from the first time begins to work. Someone in general indicates that the absolutely new gadget at all refuses to turn on. Either he and the monitor have problems. For example, what is happening is not displayed. There can be a huge number of problems. No matter what the reason, if the user knows how to fix these or other malfunctions in the computer. That is why it is necessary to understand all these problems. Particular attention will have to be paid to the situation when the device switches itself on. After all, all other cases are often corrected without any problems.

Buttons

Is the computer turned on by itself? The first reason is the wear of the gadget. As a rule, this problem arises mainly on stationary computers. They have on the system unit a special switch - power on.

Over time, for some reason, this button may break. Or rather, it is about the contacts that connect the switch to the computer. For example, there is oxidation. Then from time to time, when the computer is turned on, a short circuit will occur, and the machine will automatically turn on.

How to deal with this situation? There are several options:

1. When you turn off the computer, pull out the power cord from the mains. Not very convenient, but 100% of the machine itself does not turn on.
2. After switching off, switch on the rear panel of the system unit to the "Off" position.
3. Update the computer. It is recommended to change the system unit.

How to act? Every user decides for himself. In fact, the last option is most often the case. But not always the computer turns on by itself because of the power button on the system unit. There are other reasons for this behavior.

BIOS Settings

For example, because of the BIOS settings and settings of the computer. To be frightened of the given term is not necessary. This is the computer control system. Older PCs had to be turned off by pressing the power button. Otherwise, the operating system continued to work, but nothing was displayed on the screen.

This feature is also preserved on new computers. Slight failure of the "BIOS" parameters - and the system will be configured to switch on spontaneously. How to fix the problem? You can act in several ways.

Among the most common methods are:

1. Contacting the system administrator for assistance. He will quickly configure the BIOS and adjust the machine.
2. Self-debugging computer options. You need to visit the "BIOS" tab of the Power Setup tab and set the corresponding parameters there.

The choice of one way or another to combat the problem depends on the user's skills. Quite often use the second option. If he does not help, then you can already turn to a specialist for help.

Sleep

Is the computer turned on by itself? This reason has several reasons for appearing. The next version of the development of events can occur on both stationary computers and laptops. It is a question of the fact that the machine was not initially turned off.

Like this? At the moment there are two functions in operating systems:

• sleep;
• Hibernation.

During operation of one of them, the computer is as if turned off. In fact, he is immersed in sleep or a waiting mode. It is often difficult to distinguish between a real PC shutdown from "sleep". That is why it may seem that the operating system switches on independently.

What should I do in this case? You really need to turn off the computer. To do this, it is recommended to check the system settings. Sometimes the sleep function actually sets "sleep" or "hibernation." The problem disappears after the computer starts to really shut down, rather than being put on standby.

Viruses

But this does not end with possible options. Is the computer turned on by itself? Then you can make sure that all previously listed layouts do not exist, and then include scanning the operating system for viruses. The thing is that the PC itself is often turned on or off because of Trojans and other dangerous malicious files.

The situation is corrected in several ways. Among them we can mention:

1. Full reinstallation of the operating system with the formatting of the hard disk. The method is radical, it is not recommended to apply it to critical positions.
2. Computer treatment. Here you can use anti-spyware, antivirus and other software to protect the operating system from malicious files. More humane, but not always effective option.

It is suggested to try to treat the computer first. If you can not fix the situation, then completely reinstall the OS. It's mandatory to format all partitions of the hard disk, otherwise there is a risk that spontaneous inclusion will continue.

Not the first time

On this with the inclusion without the knowledge of the user can finish. There are no other reasons for this problem to date. Sometimes the computer does not turn on the first time. Also not the most pleasant situation. Every user should know how to deal with this turn of events.

So, at the moment you can face the described problem for the following reasons:

1. Viruses. Because of them quite often there are different problems with the computer. Up to the damage to the "iron" of the machine. If the computer does not immediately turn on, you need to check it for dangerous files and treat it.
2. "Fall" button on. Actual for old cars. Over time, the power-on buttons can be damaged, the contacts "torn", so you can not immediately make the computer work. It helps either fixing or replacing the component.
3. Failed settings. Both in the BIOS and in the operating system itself. Sometimes it turns out that the PC power button performs a different function. For example, it immerses the operating system into sleep. You can correct the situation only by changing the settings.

In any case, if the machine turns on, this is already a good sign. Therefore, it is not necessary to panic much. If you can not fix the situation yourself, it is recommended to take the computer to a service center. There they will quickly diagnose and then adjust the work of the gadget.

Power button

What else can be connected with the inclusion of the machine being studied? There are not many situations left. Sometimes it happens that the computer does not turn on with the power button. Quite often, laptop owners face this phenomenon.

What can help fix the situation? It has already been said that the reason for this behavior lies in the downed system settings. Most likely, the power button is responsible for another function. For example, for the mode "Sleep" or restart.

To enable the computer power button to work properly, you need to go into the power settings. Further in the "Action button power" will have to set the option "Shutdown". Changes are saved. That's all. Now the computer should be turned on and off by pressing the corresponding button.

Sometimes the named failure is the result of viruses or contact rupture. The situation is corrected exactly the same as when you turn on the PC not the first time. Nothing special or difficult in this!

Monitor

Why does not my monitor turn on when I turn on the computer? This is another question that interests users. The phenomenon mainly concerns owners of stationary machines.

The monitor may refuse to work for the following reasons:

1. No connection to the system unit or network.
2. Damaged wires or connectors. Relevant components are repaired or replaced.
3. Marriage of the monitor or its malfunction. You need to connect a new device.
4. Lack of drivers or the need to update them. In this case, you'll have to try to install the appropriate software on your computer.
5. Video card problems. The component is either replaced or repaired.

But this can not finish all the problems that just happen. What else should users pay attention to?

Reloading

The penultimate layout is when the computer turns on and off all the time. Such situations do not allow working with the operating system. A phenomenon can be observed if:

1. The "battery" on the motherboard is damaged. The component is replaced.
2. There are viruses on the computer. I need treatment.
3. The BIOS settings automatically reboot the OS. It is required to change the corresponding options.
4. Hardware conflict or hardware failure of the PC. It's best to give the computer to a service center to fix the problem.

From now on it is clear why the computer turns on and off endlessly. Perhaps there was only one phenomenon left that was not considered.

Shutdown

The last thing that can cause a lot of problems is the spontaneous shutdown of the computer. It occurs on both laptops and stationary machines.

Why does this happen? Shutdown without a user command takes place if:

1. The machine overheats. Then she immediately turns off to cool.
2. The PC cooler is not working well. Or if it's clogged.
3. Viruses. Help to fix the situation of antivirus programs.
4. Timer. Sometimes the computers turn on the off timer. Then at some point the operating system will shut down. You want to disable this feature.

That's all. Now it's clear why the computer turns on by itself, turns off or reboots constantly. In fact, everything is not so difficult to understand and correct, as it seems at first glance.
