Updating your BIOS

Another way to fix random Windows problems is to update your BIOS. Navigate to the website of your motherboard manufacturer to download the most recent BIOS version. You must ensure that you have the correct version of the motherboard manual. You could end up damaging your computer. It’s best to consult a professional if you aren’t sure which BIOS you require.


Overheating can cause your computer to restart occasionally. The BIOS can be accessed to check the temperature of your computer. Your device might also need to be cleaned with pressurized air, dust cleaning, or any other method of clearing debris from openings.

Check your computer for hardware issues

You might have a hardware problem if none of these suggestions work. Make sure you check the power supply (central processing unit), and that everything is in order. Your local repair shop can check if your laptop or computer is still covered by warranty.

Mac Computer Keeps Restarting Randomly

Mac computers are well-known for their resistance to common Windows OS issues. They aren’t perfect. These are some suggestions if your Mac is experiencing problems with rebooting.

Verify Your Software

Install all updates to your Mac’s software. You may receive a notice from the operating system indicating that an app is causing your Mac to restart. If this happens, move it to “Trash” and check if the problem has been resolved.

You can also isolate the problem by turning your Mac into safe mode.

Final step: Reinstall macOS. If this doesn’t resolve the problem, you can check the hardware as described below.

Get Mac Hardware

Start by looking at your peripheral devices. You don’t need any? Skip the steps and go to the next section.

  1. Your Mac should be turned off.
  2. All printers, hard drives, or other devices should be disconnected. Desktop Mac users should leave the keyboard, display and mouse connected.
  3. Turn on the Mac.
  4. If the device keeps on restarting, check it.
  5. If it does, you can check the internal RAM or third-party hardware in the section below.
  6. Reconnect each peripheral device until the problem is resolved.

You can check RAM and third-party hardware

Some Mac models have removable RAM. Perhaps the SSD you just installed is not compatible with your system or was installed incorrectly. If possible, remove it and test the system with the original memory or disk.

Contact Apple Support if none of these steps work.

Windows 7 Computer Restarts Randomly

Windows 7 has been failing to open certain programs or browse the internet. The following suggestions can help you fix the problem.

The Automatic Restart Feature should be turned off

  1. Navigate to “Start” and then “Computer.”
  2. Right-click “Properties” to move to “Advanced System Settings.”
  3. Click on “Settings”, in the “Startup and Recovery” section.
  4. Under “System failure”, uncheck the box next “Automatically resume”
  5. Click “OK” to continue using the computer as normal.

If the problem recurs, please continue to the next section.

RAM issues?

Random restarts may occur if your RAM is damaged. To determine if RAM is the problem, you can use MemTest86 and a benchmarking test.

MemTest86 can be downloaded on your computer. The app will then run automatically. For accurate results, run six to seven scans. A bad RAM is indicated by a red result.

Follow these steps to run a benchmarking exam:

  1. Click the “Windows Key + R”, and type “perfmon/report” into your Performance Monitor.
  2. Allow the system to collect data for 60 seconds.

The “Diagnostic Results Tab” will display the results. The section will include three sections: Informational, Basic System checks, and Resource overview. You’ll also find the “Warnings” section if your computer is experiencing severe issues. If that doesn’t happen, you can look under “Resource Overview” for RAM problems.

Replace or check the power supply

If you suspect that dust or dirt is affecting your power supply, this step will help.

  1. Turn off your computer and unplug it.
  2. Unlatch or unscrew the back cover of your laptop or the side cover of your PC casing. A small box will be found in the corner with a fan and a rating label. This is the power supply.
  3. Remove wires from your motherboard.
  4. After you have disconnected the cables, unscrew the power supply.
  5. Check for any blocked air passages or dust in your power supply. It can be cleaned and put back.


Did you notice that your computer randomly restarts after running a particular program? Your CPU could be overheating, causing random restarts. To investigate the problem, you can either use third-party software like CPUID or your computer’s built in sensors.

HWMonitor can be downloaded here. It is easy to install on your computer. A list of processes will be displayed and their temperature values. After running a task-intensive programme, check for temperature.

Your built-in sensors can also be used. Follow these steps to do this:

  1. Reboot your computer or laptop.
  2. When the Windows logo appears, press F2. For Dell devices, press F10.
  3. Then you’ll be transferred into BIOS. If you don’t see the menu, there will be other options. Once you are there, select BIOS with your arrow keys. Hit “Enter” to exit.
  4. Use the arrow keys for H/W monitor selection and hit “Enter.” Alternately select “Status”, and hit “Enter.”

The system will display temperature and voltage readings on your computer. These readings should not exceed certain limits. If they are not within the limits, your device could be experiencing an overheating problem.

Clean your system and check that the fan is working properly to solve the problem of overheating. Your thermal paste, a gel-like substance, may need to be replaced or cleaned. Heat sinks are small objects that absorb and distribute heat evenly.

Computer randomly restarts while gaming

You might want to give these suggestions a try if your computer keeps rebooting when you are gaming.

Prevent Overheating

The most common reason a computer restarts while playing is when the CPU becomes too busy. Clean your computer regularly to prevent this from happening. Make sure to clean the dust off your computer and that the fans are working properly. If the fan noises continue to be a problem after cleaning, you may need to replace the CPU cooler.

Look out for GPU issues

Your GPU (graphics processing device) may be the problem. You can unplug the GPU and make use of the integrated graphics. If your computer does not restart, you need to have your graphics card checked.

You should also ensure that your cooling system is working properly and update your drivers regularly.

Take control of your PC

Random restarts are the most annoying thing for computer users. This problem is annoying, but can be easily resolved in most cases. This article will provide solutions for Windows and Mac devices, so that restarts don’t happen again.
