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

Computers are machines that give users a lot of trouble. If the device works fine, then the gadget makes life much easier. But in the case of certain failures, serious problems begin. Often, users complain that the computer turns on by itself. Or not the first time it starts to work. Someone generally points out that a completely new gadget refuses to turn on at all. Or he starts to have problems with the monitor. For example, what is happening is not displayed. There can be a lot of problems. It doesn’t matter what the reason is if the user knows how to fix these or other computer malfunctions. That is why it is necessary to understand all of these problems. Particular attention will have to be paid to the situation when the device itself turns on. After all, all other cases are often corrected without any problems.

Buttons

Does the computer turn on by itself? The first reason is gadget wear. As a rule, this problem occurs mainly on stationary computers. They have a special switch on the system unit - turning on the power.

Over time, for one reason or another, this button may break. More precisely, we are talking about the contacts that connect the switch to the computer. For example, oxidation occurs. Then, from time to time, when the computer is connected to the network, a circuit will occur, as a result of which the machine will turn on spontaneously.

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

1. When turning off the computer, pull out the power cord from the network. Not too convenient, but 100% of the car itself will not turn on.
2. After turning off, set the switch on the back of the system unit to the off position
3. Refresh computer. It is recommended to change the system unit.

How to act? Each user decides for himself. In reality, the latter option most often occurs. But the computer does not always turn on by itself because of the power button on the system unit. There are other reasons for this behavior.

BIOS options

For example, due to the parameters and settings of the BIOS of the computer. You should not be afraid of this term. This is the name of the computer control system. Old PCs had to be turned off without fail by pressing the power button. Otherwise, the operating system continued to work, but nothing was displayed on the screen.

This feature has been preserved on new computers. A minor failure of the BIOS settings - and the system will be configured to turn on spontaneously. How to fix the problem? There are several ways to act.

Among the most common methods are:

1. Seeking help from a system administrator. He will quickly configure the BIOS and adjust the machine.
2. Self-debugging computer options. You need to visit the Power Setup tab in the BIOS and set the appropriate parameters there.

The choice of one way or another way to deal with the problem depends on the user's skills. Quite often they use the second option. If it does not help, then you can already seek help from a specialist.

Sleep

Does the computer turn on by itself? This reason has several reasons for the appearance. The next scenario can be found on desktop computers and laptops. It is about the fact that the machine was not initially in the off state.

Like this? There are currently two functions in operating systems:

• sleep;
• hibernation.

During the operation of one of them, the computer is, as it were, off. In fact, he is immersed in sleep or standby. It is often difficult to distinguish a real PC disconnect from "sleep". That is why it may seem that the operating system turns on itself.

What to 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” or “hibernation” is actually set on the shutdown function. The problem will disappear after the computer starts to really turn off, and not put into standby mode.

Viruses

But the options do not end there. Does the computer turn on by itself? Then you can make sure that all the previously listed layouts do not take place, and then turn on the scanning of the operating system for viruses. The thing is that the PC often turns itself on or off due to trojans and other dangerous malicious files.

The situation is corrected in several ways. Among them are:

1. Complete reinstallation of the operating system with formatting the hard drive. The method is radical, it is not recommended to apply it to emergency situations.
2. Computer treatment. Here you can use anti-spyware, antivirus and other software to protect the operating system from malicious files. A more humane, but not always effective option.

It is proposed to first try to treat the computer. If you cannot correct the situation, then completely reinstall the OS. It is imperative to format all sections of the hard drive, 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, you can end. No other causes of this problem have been found to date. Sometimes the computer does not turn on the first time. Also not the most pleasant situation. Each user should know how to deal with such a turn of events.

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

1. Viruses. Because of them, quite often there are various problems with the computer. Up to damage to the "iron" of the machine. If the computer does not turn on immediately, you need to check it for dangerous files and treat it.
2. "Sinking" of the power button. Actual for old cars. Over time, the power buttons may become damaged, the contacts "break", and therefore can not immediately make the computer work. Either repairing or replacing a component helps.
3. Broken 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, immerses the operating system in sleep. 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 worth panic. If you cannot correct the situation yourself, it is recommended that you take the computer to a service center. They will quickly carry out diagnostics, and then they will adjust the work of the gadget.

Power button

What else can be connected with the inclusion of the studied machine? There are not so many situations left. Sometimes it happens that the computer does not turn on with the power button. Quite often, owners of laptops face a similar 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 "Sleep" mode or reboot.

For the power button to work normally, you need to go to the power settings. Next, in the "Power Button Action", you will have to set the "Shutdown" parameter. Changes are saved. That's all. Now the computer should turn on and off by pressing the appropriate button.

Sometimes called a malfunction - a consequence of viruses or broken contacts. The situation is corrected in the same way as when you turn on the PC not the first time. There is nothing special or difficult about this!

Monitor

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

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 being repaired or replaced.
3. The 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 will have to try to install the appropriate software on the computer.
5. Graphics card problems. The component is either replaced or repaired.

But even this cannot end all the problems that only take place. What else should users pay attention to?

Reboot

The penultimate scenario is when the computer turns on and off constantly. Such situations do not allow you to work with the operating system. A phenomenon may occur if:

1. Damaged "battery" on the motherboard. The component is replaced.
2. There are viruses on the computer. I need treatment.
3. BIOS settings automatically restart the OS. It is required to change the corresponding options.
4. Hardware conflict or PC hardware failure. It is best to take 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 is only one phenomenon that has not been considered.

Off

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

Why is this so? Shutdown without a user command occurs if:

1. The machine is overheating. Then it urgently shuts off to cool.
2. The PC cooler is working poorly. Or if it is clogged.
3. Viruses. Antivirus programs help fix the situation.
4. Timer. Sometimes the computers turn off the off timer. Then at certain times the operating system will turn off. It is required 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.
