Computer randomly restarts

Automatic restart of the computer in some cases happens; for example, after updating the system, correcting system errors, etc. However, there are times when the computer automatically restarts spontaneously without any warning messages in the middle of your work.

This accidental reboot can cause a lot of problems, as you may know. When it happens, you are unlikely to be able to save anything you were working on in time, which can be bad for you personally and professionally. To prevent this from happening and stop computer reboots from happening at bad times, read this article and study it carefully. You will get as much information as possible about the “computer reboots randomly” problem.

Why does my computer randomly restart?

This problem can be caused by many things:

  • Incorrect auto-restart function
  • Overheating or faulty power supply
  • Damaged RAM
  • Driver problems
  • Virus or malware
  • Updating Windows, etc.

How to deal with random restarts?


Turn off automatic restarts

By right-clicking "This Computer", select "Properties".

In the new pop-up window, click “Advanced System settings” and select the Advanced tab. Click “Options” in the “Startup and Recovery” section and uncheck the “Auto Restart” box in the “System Crash” section. Now click "OK" and check if the problem is gone.

Configure power settings

To do this, go to Power Options and go to the "Change plan settings" section. Next, select "Change advanced power settings" and at the bottom you will see the line "Processor power management"; click on it.

Next, select “Minimum Processor Health” and specify “On Battery and Plugged in as 5%”. Save all changes; after that, accidental reboot won't bother you anymore.

Check graphics driver

If the computer does not recognize the graphics driver, the system can automatically reboot. Try updating or even reinstalling your graphics driver.

Open Device Manager and navigate to Display Adapters. Then select "Delete" from the context menu. In the "Confirm to remove device" window, highlight "Remove driver software for this device", and click "OK". After restarting your computer, installing the driver will happen automatically.

To update the graphics driver, right-click the driver in Display Adapters and select “Update Disk Software”. Then follow the instructions of the Wizard to complete the update.

Overheating issues

Overheating a computer always entails a system reboot. Therefore, check all ventilation outlets, clean them if necessary, or take them to a service center to have them professionally cleaned. This should result in no more sudden restarts of your computer.

Power supply

One of the cables connected to the computer may be loose or damaged. In this case, the connection will be broken and the system will reboot from time to time. Replace the broken cables with new ones and the problem will be solved.

Update the BIOS

Perhaps your BIOS is outdated. Check the official website for your BIOS for available updates and install them.
