How to fix a computer that randomly restarts

If you are a regular PC or laptop user, there might not be anything as annoying as your device periodically rebooting itself. This is not only unpleasant, but it also causes you to lose important work in progress.

If you’re having trouble with your computer’s random restarting and you want answers, you’ve come to the right place. This article will share tips to solve the problem on Windows 10, 7 and Mac. Learn how to regain control of your device with ease.

Random reboot of Windows 10 PC

If your Windows 10 restarts as soon as you open a program, don’t worry. Many users experience the same problem. Below are the most common solutions to Windows 10 random restart problem.

Disable the automatic restart function

A common reason a computer randomly reboots is that a feature tells it to do so. Check if this is the problem by following the steps below:

  1. Enter “This PC / My Computer / Computer” in the search box next to “Start.”
  2. Right click on the result.
  3. Go to “Properties”.
  4. Go to “Advanced system settings”, then to “Settings …”
  5. Uncheck the “Automatically restart” function and press “OK”.

You have now disabled the feature that causes your computer to randomly reboot. Keep working on your PC to see if the problem is resolved.

Maybe there is an automatic driver update that requires your PC to restart every time. If you are sure that your drivers are installed correctly, you can disable the automatic driver update feature.

  1. Navigate to the Windows search bar and enter “Advanced Settings.”
  2. Select “View advanced settings” from the results.
  3. Go to “Hardware” and then “Device Installation Settings”.
  4. Check “No (your device may not work as expected)” and select “Save changes”.

Adjust power settings

Another reason your computer may be restarting is that the power settings are not configured correctly. Here’s how to reconfigure the settings to hopefully solve the problem:

  1. Enter “Power Options” in the search box on your Windows 10.
  2. Select “Edit power plan” or similar items in the power settings.
  3. Select “Change advanced power settings”.
  4. Stay in the “Balanced” section and click on “Processor Power Management.”
  5. Select “Minimum processor state” and set it to 5% or even 0%.
  6. Click “Apply” and then “OK”.

If your computer continues to restart after editing the power options, continue to the next section.

Update your BIOS

Updating the BIOS is another way to resolve random Windows crashes. Just navigate to your motherboard manufacturer’s website and get the latest BIOS version. It is essential to consult your motherboard manual for the correct version. Otherwise, you risk damaging your computer. If you are not sure which BIOS you need, it is best to contact a professional.

Check for overheating

If your PC overheats, it can cause occasional reboots. You can check the temperature of your computer by accessing the BIOS or with any third-party software. Also, your device may need some pressurized air or dust cleaning to clear vents or other openings of debris.

Inspect your computer for hardware problems

If none of the above suggestions work, a hardware problem may be causing you to randomly reboot. Check the CPU (central processing unit) or power supply and make sure they are in perfect order. If your laptop or PC is still under warranty, have it checked at your local repair shop.

Mac computer keeps rebooting randomly

Mac computers are known to be resistant to many common Windows operating system problems. However, they are not perfect. If you have a restart problem with your Mac, try the suggestions below.

Check your software

Make sure to install all software updates on your Mac. If the operating system indicates that an application is causing the restart, you may see a warning suggesting moving it to the Trash. Go ahead and see if the problem is fixed.

Also, you can isolate the cause by running your Mac in safe mode.

Finally, you can reinstall macOS. If the problem is not resolved, check the hardware as detailed below.

Check Mac hardware

You want to start by checking your peripheral devices. If you don’t have any, skip the steps below and continue to the next section.

  1. Turn off your Mac.
  2. Disconnect all printers, hard drives, and other devices. For desktop Mac users, leave the keyboard, display, and mouse connected.
  3. Turn on the Mac.
  4. Check if the device continually reboots.
  5. If so, check the internal RAM and third-party hardware in the next section.
  6. If not, reconnect each peripheral device until you find out what is causing the problem.

Check RAM and third-party hardware

Some Mac models come with removable RAM. Maybe the SSD you recently installed is not compatible with your system or is not installed correctly. Remove it if possible and run a test with the original disk or memory.

Check for RAM problems

If there is a problem with your RAM, it may result in random reboots of your PC. Use MemTest86 or run a benchmarking test to find out if RAM is causing the problem.

To use MemTest86, simply download it to your computer and the application will launch automatically. Run six or seven scans to get accurate results. Red result means bad RAM.

Run a benchmarking test by following the steps below:

  1. Open your Performance Monitor by pressing “Windows Key + R” and typing “perfmon / report”.
  2. Wait 60 seconds for the system to collect data.

The results will be visible in the “Diagnostic Results” tab. There will be three sections: Informational, Basic System Checks, and Resource Overview. If there is any serious problem your PC is facing, you will also see the “Warning” section. If not, look for RAM problems in “Resources Overview”.

Check or replace the power supply

Use this step if you think dust or dirt may be affecting your power supply.

  1. Shut down the computer and unplug the system.
  2. Open the side cover of the PC case or the back cover of your laptop by unhooking or unscrewing. There will be a small box in one corner with a fan and a rating sticker. This is the power supply.
  3. Disconnect the cables connected to your motherboard.
  4. Unscrew and unhook the power supply once you disconnect the cables.
  5. Look for blocked airways or dust in the power supply. Clean it up and return it all.

Check for overheating

Have you noticed that your computer randomly reboots after running a specific program? If so, your CPU may be working too hard and causing the device to overheat, leading to random reboots. You can use third-party software such as CPUID or your PC’s built-in sensors to investigate the problem.

You can download HWMonitor PRO here. Just install it on your computer and launch it. You will see a list of processes and their value in terms of temperatures. Check temperatures after running a task intensive program.

You can also use its built-in sensors. To do so, follow the steps below:

  1. Restart your PC or laptop.
  2. Press F2 when the Windows logo appears. For Dell devices, press F10.
  3. You will be transferred to BIOS. Otherwise, you will see a menu with different options. Select BIOS using the arrow keys and press “Enter” once you are there.
  4. Use the arrow keys to choose H / W monitor and press “Enter.” Alternatively, select ‘Status’ and press ‘Enter’.

The system will display temperature and voltage readings for your PC. Readings should be within limits. Otherwise, it means that your device may have an overheating problem.

To solve the overheating problem, clean your system and make sure the cooling system (fan) is in order. You may need to replace your thermal paste (a gel-like substance) or clean your heat sinks (small objects that attract and evenly distribute heat).

Computer randomly restarts while gaming

If your computer continually reboots while gaming, you may want to try one of the suggestions below.

Prevent overheating

One of the most common reasons a PC reboots during gaming is because the CPU is too busy. To prevent this from happening, you must clean your computer. Clean the dust from the PC and make sure the fans are working properly. If nothing changes after cleaning the fans and the CPU continues to overheat, consider replacing the CPU cooler.

Check for problems with the GPU

If your computer mainly reboots while gaming, the problem may be with your GPU (graphics processing unit). Unplug your GPU from the device and use the system’s integrated graphics. If the computer no longer restarts, it means you need to check your graphics card.

Also, always make sure you have a proper cooling system and do regular driver updates.

Take back control of your PC
