The computer itself turns off: causes and solutions

“Help, the computer itself is turned off!” approximately this message can be found on various forums related to computer topics. Faced with the same dilemma? Then you have come to the right place! Today we will tell you what may result in spontaneous shutdown of the PC and how to fix it!

The computer itself is turned off: the most common causes and their solutions

1. Overheating PC components

Let’s start with the most common reasons for self-termination computer: overheating of components. Increasing the operating temperature of the CPU, GPU, PSU, and other hardware to critical indicators easily can cause a PC shutdown. Overheating occur for different reasons:

  • a strong accumulation of dust and other pollutants;
  • malfunctioning cooler;
  • poor air circulation in the system unit;
  • the dried up thermal grease;
  • excessive overclocking.

To check the temperature of various equipment, simply use the services of specialized software. Programs to measure the temperature a lot and generally they are distributed for free. Here is a list of the most popular FOR watching the temperature (and not only!):

  • MSI Afterburner;
  • SpeedFan;
  • Open Hardware Monitor;
  • Core Temp;
  • CPU-Z;
  • AIDA64;
  • GPU-Z;
  • HWMonitor.

Specify maximum operating temperature for each of your glands in the Internet and verified against the data in one of these programs. “Burn” the CPU? Help cleaning old or installing a new cooler, replace the thermal paste. The graphics card used roughly the same steps. If heated the North or South bridge on the motherboard, it may help to install additional radiators. Once you eliminate overheating, your computer itself off will definitely stop.

2. A faulty power supply

The processing brain of the computer and the power supply is its heart. If your PC constantly turns itself off (or restarts frequently), the power supply can be cause.

Unfortunately, in the home to perform a precise diagnosis can not everyone. However, there are a couple of obvious signs of a faulty PSU, which will catch any user. First, just test the PSU and see how hot air blown out of him. Secondly, the smell — it smells something unpleasant?

The answer is obvious, when the computer itself is turned off, the power supply will not touch, and he smells. In this case, we recommend that you either go in service to the local guys tried to revive him, or to shell out for a new PSU.

3. Problems with RAM

Random access memory (or simply RAM) is another component of the computer that may cause it to shutdown, if that is not working properly. The most obvious signs of problems with RAM is a blue screen of death, slow performance and intermittent errors while performing certain actions in Windows.

RAM you can check the system and third party software. To run the Windows memory diagnostic, you need to do the following:

  • press Win+R to call up the window “Run”;
  • list the value mdsched.exe and press Enter;
  • in the resulting window, click on “restart now and check for problems (recommended)”.

Next, your computer will restart and the standard start testing RAM. You can change the testing options by pressing F1 to select a wide range of tests for more accurate testing.

As soon as the test memory completes, your PC will reboot. Next you need to go to the “event Viewer” and see the results of the testing that is done like this:

  • press Win+R;
  • list eventvwr.exe and press Enter;
  • go through the “Windows Logs→System”;
  • click on the icon “Find…” from the right side of the window;
  • write the value of MemoryDiagnostics-Results and click “Find next”;
  • double click the found event and read the test results.

Here you will immediately understand, whether all is normal with your RAM or not. If the RAM there are some problems, then you probably will have to replace it.

4. Problem with HDD/SSD

Hard (HDD) or solid state (SSD) drive — the PC component that stores your operating system. If this unit fails or starts to work incorrectly, the problem guaranteed — to the extent that the computer will start itself off.

Problem with HDD/SSD can be divided into two categories: hardware and software. The first category can be attributed to corrupt file system, bad blocks. Both you can try to fix Windows tools or third-party software. To use the system tool, do the following:

  • open “This PC”;
  • right click on the system drive and select “Properties”;
  • go to the tab “Tools” and click on “Verify”;
  • click on the button “Verify disk” in another window;
  • wait until check disk and check the results.

With hardware problems a bit more complicated. Here is a list of possible problems with the HDD:

  • the failed controller, BMG or the switchboard-preamplifier;
  • a damaged power cable or SATA;
  • damaged HDD motor;
  • damage to the magnetic platters;
  • and more.

SSD, unlike HDD, has no moving parts and works about as well as any flash card. So with SSD experience several other problems:

  • a breakdown of the controller;
  • defective memory chip;
  • problems with the connection interface of the disk;
  • and more.

In the case of a hardware failure you almost certainly have to seek assistance from the local service center.

5. Specific Windows settings

Maybe your computer turns off on its own because your Windows is set to a sufficiently specific settings. Spontaneous PC shutdown may occur if you install parental control or presence of the corresponding task on the scheduler. In the first case everything is clear: trying to persuade my parents to remove the restrictions or tries with reality.

Tasks disabling the PC can be created the same. For example, users often forget to untick the option that is responsible for turning off your PC, the installer of some program or game. Antivirus, media players, utilities for recording, download managers files, etc. — all it can create on your computer a task to automatically shutdown.

Just be careful when working at the computer and it will never itself off.

6. Viruses and malware

Some viruses and is not a credible program can significantly harm your PC — so much so that he starts himself off. If none of the above not apply to you, then we suggest you scan Windows for viruses. At the recent installation — get rid of it. Testim system and see if it helped.

7. Own negligence

Decided to clean your disk from junk? You could delete critical OS files, especially if the cleaning was conducted in the Windows folder on the system partition. And now, when the OS tries to access remote files, an error occurs and the PC shuts down. In such a situation it is better to use Windows recovery and even to reinstall it.

The situation has not changed? The computer itself turns off, despite all your actions? It’s time to go to the service center…
