How to Fix Your Computer Randomly Turning Off

Computer Randomly Turning Off

The computer randomly shutting down can be a frustrating and annoying problem. The good news is that it's usually an easy fix. Here are some possible solutions for when your computer shuts down randomly.

Why Does the Computer Randomly Shutdowns?

The computer randomly shuts off when it is running on battery power. This is because the computer's processor has to work harder to run on battery power, which causes the fan to speed up and generate more heat. If a laptop is not cooled properly, it will shut down to protect itself from overheating.

Common Problems with Windows Operating System That May Cause Computer Random Shutdowns

If your computer shutdowns, then here are some tips to help you solve your device issues:

  • Suppose your computer has overheated (your PC's CPU should never be above 80 degrees Celsius, or the heat will ruin it in the long run). In that case, you should clean the excessive dust and try to improve the airflow with your computer fans. To measure your computer's temperature, we recommend you use MWSoft software. Its Health section will automatically scan your computer hardware to find potential hardware malfunctions so that you can resolve the issue.
  • Your computer's power supply may have applied security measures to prevent higher voltage. You may need a better power supply with higher voltage.
  • Disable fast startup: Windows 10 Start -> Power Options -> Choose what the power buttons do -> Change settings that are currently unavailable -> Shutdown settings -> Uncheck Turn on fast startup -> Click Ok.
  • Your computer may have a faulty power supply, so you should buy a new one.
  • There is a chance that you have a virus in your computer that has shut down your computer. In this case, we recommend ESET antivirus, which will scan your computer to find potential viruses.
  • You should update all your computer drivers from the device manager of Windows. An outdated driver could cause your computer's shut down problem.
  • If your computer keeps shutting down, we recommend you unplug it for ~5 minutes and then plug it in again. If it keeps closing, you may have hardware issues, and you have to buy new hardware.
  • Your RAM may have reached its maximum capacity.
  • Check and make sure that your computer video card fans, processor fans, or case fans are spinning correctly. If not, then your computer may have overheated. You should ensure your computer's processor temperature is not too high. Your graphics card may be faulty, so you have to buy a new one. Your motherboard or CPU may have reached its maximum capacity or experienced hardware failures.
  • Remove your power cord for ~5 minutes if you're on a laptop, then plug it in again.
  • If none of this work, you may want to try to update your Windows 10 PC or even completely reinstall it.

Why the Computer Randomly Turns off While Gaming?

The computer randomly turns off, while a few different things can cause gaming. The most common reason is overheating. This is because the heat generated by the GPU and CPU can't escape the case and causes both components to shut down to prevent damage. If the computer randomly shuts down while gaming, it's essential to check that there's sufficient airflow inside the case or that you're not running too many programs simultaneously.

If you have enough airflow in your case and are not running too many programs at once, then your power supply might be faulty. This could cause your computer to randomly turn off while gaming because it doesn't have enough power for everything you're running on it.

Why the Computer Randomly Turns off but Fans Still Running?

In this case, your computer isn't off, but your GPU may be defective.

Why the PC Randomly Turns off and Restarts Windows 10?

A PC randomly shuts off and restarts Windows 10 can be caused by several factors.

Some of the most common causes are:

  • The PC has overheated and needs to cool down before it can turn back on.
  • The PC is not getting enough power from the power supply, and you may need to replace the power supply.
  • The PC's graphics card is overheating and needs to be cooled down before it can turn back on.
  • The PC's hard drive is failing and needs to be replaced.
  • A virus or malware has infected your PC, which requires a system restore or other measures.

Driver Cause PC to Shut Down

In this section, you will find out why your PC might shut down.

The power management on Windows is designed to turn off the computer when it is inactive for a specified time. This feature is implemented through a driver. When the driver detects that the computer has been idle for an extended time, it sends a signal to Windows to request that Windows put the computer into sleep mode or shut it down.

There are also settings and power policies configuring through the Power Options in Control Panel.

The hibernation feature allows the computer to go into a low-power state similar to sleep mode, but without completely shutting down the computer.

This is accomplished by writing a small amount of data, such as those saved in RAM, to a file on disk and then rebooting. On restarting, the operating system loads from that file instead of from scratch. Hibernation saves all the data in RAM to disk and then shuts down the computer.

This allows you to resume your work where you left off when you boot the computer. For example, suppose you were working on a document. In that case, hibernation can be used to save it so that it remains accessible when the computer is restarted.
