Top 5 reasons why a computer keeps shutting down

Many people said that they felt annoyed by the situation or had met it before: the computer randomly shuts down or the laptop randomly turns off. You have a question on your mind: Why does my computer keep shutting down? Let's take a look at that.

#1. Power supply problem

First of all, you should check the power supply: whether it is well connected and whether the supply is stable. A faulty power adapter, battery, or charger can cause your computer to malfunction and even shut down. You will also find that the computer keeps turning itself off when the charger does not have enough voltage.

Then check the following things.

# 2. Overheating

Most computers on the market today are designed to shut down unsigned when internal components overheat. Although there are heat sinks and fans that help cool the CPU (Central Processing Unit), it still sometimes overheats, resulting in an unexpected shutdown of the computer / laptop. You should suspect overheating if your PC accidentally turns off after a long period of work (playing computer games or editing / watching videos).

Tip: Dust, dirt, scraps of food, hair, or other things could be the cause of overheating as they hinder effective heat dissipation and block proper airflow. So please remember to keep your computer clean.

# 3. Hardware failure

Another common cause of computers turning off randomly is hardware failure. It can happen that the PC randomly shuts down if one of the hardware components suddenly fails. In this case, you should look for hardware failures.

There are two ways to check for hardware errors:

  • Remove the non-essential hardware (one at a time) while the PC is switched off -> restart the PC for diagnosis.
  • Open Device Manager -> look for a special marker that shows the error.

When you find the faulty component, please replace it with a new one that should be compatible with your computer.

Tip: If you recently added new hardware to your PC, please try removing it and restarting the PC to see what happened.

# 4. Virus and malware

Computer viruses and malware are another common factor responsible for turning the computer on and off. Viruses, malware, trojan horses, and worms are developed by malicious individuals to attack other people's devices, including computers. Some of them are programmed to shut down your system under certain conditions once your computer is infected. (Please use Windows Defender or third party software to protect your PC).

You should suspect that your computer is being attacked by a virus or malware if it shuts down when you run a certain program / tool at certain times (e.g. your laptop keeps shutting down on startup). On this occasion, you should immediately delete the virus with a powerful antivirus program. But don't forget something else - data recovery after a virus attack.

We are happy to provide solutions to users to help them quickly and safely recover files that have been deleted by virus attacks.

# 5. Operating system error

Many operating system errors can cause the computer to shut down randomly. Some serious problems can even prevent your computer from turning on again (e.g. operating system not found). This part lists some of the most common errors (the list is in random order).

Error 1: quick start

The quick start function was developed to reduce the time the computer takes to start up after a shutdown. Your user account will be logged out and the applications will be closed as usual if the quick start function is activated. The function helps to save the current system state in the hibernation file so that the system does not have to reload the kernel, system files and drivers. This will reduce the boot time.

However, it can lead to an unstable system - your computer turns itself off, that's one of the phenomena. In such circumstances, you should try to disable this feature.

Please deactivate the quick start if your computer accidentally shuts down Windows 10 (the step-by-step instructions will be given later).

Error 2: Problem with the device drivers

Also, if any of the device drivers are incompatible, out of date, damaged, or missing, you will find the computer shut down without warning. That reason is a driver crash. What you should do at this point is try to identify the problematic driver and fix the error.

You can open Device Manager to look and see if there is a yellow warning label in front of the devices (the yellow warning label indicates an unknown device). If so, please correct the problem by updating the driver.

Error 3: Operating system installation damaged

It causes the computer to shut down again and again when there are problems at the operating system level.

How to check this:

  1. Restart your computer after it shuts down.
  2. Press the appropriate key to enter the BIOS setup.
  3. After entering the BIOS setup, leave the computer alone for a while.
  4. If the computer does not shut down, it indicates that your operating system installation is damaged or corrupt; if it still shuts down, you should suspect a hardware problem.

In the first case, you should restore your system to an earlier point where the random computer shutdown did not occur (you can also try resetting the computer or reinstalling the system from scratch); while in the second case, you can consider locating the problematic hardware component and repairing / replacing it.

Error 4: Sleep mode malfunction

The Sleep moderefers to a power-saving state of the device. When it is activated on the computer, all actions will be stopped and all open files, programs and applications will be written to the memory so that it can access the power saving mode. You can wake a computer from sleep in a matter of seconds.

However, when sleep mode does not work properly it will result in random shutdowns. You can try to fix this problem by turning off sleep mode.

Error 5: Out of date BIOS

If you find the computer turning on and off and this phenomenon keeps popping up, the cause could be in your BIOS - it may be out of date (damaged or corrupt). Therefore, you should seek professional help in updating the BIOS.

Other problems you may encounter:

  • UPS or surge protection problem
  • Overclocked CPU or GPU
  • Windows registry problems
  • Corrupted or missing system files
