Why Is My Computer Shutting Down By Itself?

Most computers are designed to shut down themselves when they become too hot or if you have the shutdown timer. This safety measure prevents electronic components from overheating and becoming damaged or unusable. If your computer is routinely shutting down, this could be because of the following:

1. Poor ventilation

If your computer is enclosed or near a wall, the fans may be unable to cool it properly. Your computer needs fresh air to cool itself effectively. You should make sure that nothing is blocking the fans or restricting airflow around your computer or laptop.

2. Overclocking

Overclocking is when you increase the speed of your computer’s CPU beyond its normal settings. This can put a lot of strain on the system and cause it to overheat if not done properly.

What is clocking?

CPU clocking is the process of pushing a CPU beyond its maximum speed. Increasing the CPU’s clock rate can make it faster and more powerful. However, this also increases the heat it produces – if not done correctly.

3. Faulty hardware

Hardware malfunctions can cause your computer to overheat and shut down. If you suspect that a piece of hardware is causing the problem, try replacing it with a new one. Hardware can be any components from your computer, such as a graphics card, RAM or hard drive.

4. Outdated software

When was the last time you updated your computer software? Outdated software can be prone to glitches and can cause problems.

Try updating all of your programs to the latest version. An update ensures your computer runs smoothly and can help prevent it from shutting down.

5. Too many programs running

Running too many programs simultaneously can put a lot of strain on your computer’s system. This means they are sharing the resources your hardware can handle beyond the lit. Try closing the software you are not currently using to free up resources and reduce heat build-up.

Now that you know the possible causes of your computer shutting down by itself, let’s look at how to fix my computer from shutting down by itself.

How to Fix My Computer From Shutting Down By Itself

Method 1: Disable First Startup

A first startup is a program set to run every time your computer boots up. If you have too many programs running, they can overload the system and cause it to shut down. To prevent this, you should turn off any unnecessary startup items on your computer.

To do this:

1. Open your Windows control panel by typing “Control Panel” into the search bar. From the panel, choose Hardware and Sound, then the power option, and choose “Change what the power button does.”

2. Select “Change settings that are currently unavailable” and uncheck the box next to “Turn on fast startup (recommended).”

3. Click “Save Changes” and restart your computer

Method 2: Check Your Computer Cooling System

Your computer needs an efficient cooling system in order to prevent overheating. Your space should have adequate air circulation, and you should check your cooling fan to ensure it is working properly. If the fan is noisy or not running, it may need to be replaced. To check if your fans are working, move to a quiet place and turn your computer on.

Method 3: Update Windows

Microsoft keeps releasing updates and patches for Windows to fix any existing issues. If Windows is outdated, it runs into bugs and glitches, making your computer shut down randomly. 

You should check for any updates available and install them to prevent this from happening. To update your windows to the latest version, follow these steps:

1. Click on the Windows icon in the taskbar and select “Settings.”

b. Select “Update & Security” then “Windows Update

c. Click “Check for Updates” and follow the instructions.

Method 4: Update Drivers

Obsolete drivers are a common problem. You need to update your drivers for them to function properly. 

A driver is software that tells your computer how to interact with hardware so that an outdated driver can cause issues. They add a functionality or feature to your computer.

This means the system and hardware communication becomes faulty, resulting in random shutdowns. 

To update your drivers: Start menu-> Settings -> Windows Update -> Advanced Options -> Optional updates -> Select drivers. You will have to install the “Pending drivers updates.”

Method 5: Roll Back Drivers

Microsoft knows very well that updated drivers can cause unexpected issues on your computer. 

As a result, you can roll back the drivers to their earlier version to fix any problem associated with them. To do this:

1. Go to Device Manager. Click the Windows icon and type in “Device Manager

2. Click on Display Adapters to expand the category.

3. Right-click on the driver and select “Properties.

4. Select the “Driver” tab and click “Roll Back Driver.

5. Follow the instructions on the screen to complete the process.

Method 6: Troubleshoot BSOD Errors

When the computer crashes and restarts, it can be due to a BSOD error. This is an error caused by a conflict between drivers or software.

It leads to a blue screen of death and can be hard to fix. The computer restarts and head to the same error if nothing has been done to fix the problem. 

The appropriate way to solve BSOD errors is to get the related code and research it. You can use Google or other search engines to find the cause of the error.

Method 7: Check Malicious Software

Installing software from unverified vendors can introduce malicious software to your computer. 

The bugs in this software can cause the system to crash and restart. Installing software from reliable sources, such as Microsoft or Apple. 

If you suspect a program is causing your computer to crash, try uninstalling it and see if the problem persists. You can uninstall the recently installed software to check if it is the root cause of the shutdown.

Method 8: Clean Your Computer

Over time, dust accumulates on computers. This might be a good time if you’ve never opened your system. Your old thermal paste may need to be cleaned and a new one applied.

Open up the case of your computer and clean out any accumulated dust. Make sure to use a compressed air can or vacuum cleaner to remove the dust. If for the case of thermal paste, click here to get the full guide.

Method 9: Run the SFC and DISM Tools

Scanning the System File Checker (SFC) and Deployment Imaging Servicing Management (DISM) tools can help you identify and fix errors in your system. 

The SFC tool scans for corrupted system files and restores them to their original versions while DISM repairs any broken or missing components. 

You can run these tools from the Command Prompt, a text-based interface for entering commands.

Method 10: Run CHKDSK

Run CHKDSK to scan and fix any errors on your hard drive. This can help prevent data corruption, which could cause random shutdowns. To run this tool:

1. Open Command Prompt (as Admin)

2. Type in: chkdsk c: /r

3. Press Enter, and the tool will scan your hard drive for errors.

Method 11: Perform a System Restore

A system restore will undo any changes made to your computer and can help you fix the random shutdown issue. To perform a system restore:

1. Press “Win+R” to open the Run window and type in “rstrui”

2. Press Enter and select “Choose a different restore point.”

3. Select a restore point earlier than the time you started experiencing the issue and click “Next.”

4. Follow on-screen instructions to complete the system restore.

Method 12: Reinstall Windows

If all of the above fails, you may have to reinstall Windows. This will completely erase your files and settings, so create a backup before proceeding. You can use a USB or external hard drive to back up your data. To reinstall Windows:

1. Insert the installation media (USB/CD/DVD drive)

2. Boot your computer from the installation media

3. Follow the installation wizard to install Windows

4. Once installed, enter the product key and complete the setup process.

Final Words

In conclusion, a multitude of methods can resolve random computer shutdowns. These measures range from updating Windows and drivers to reinstalling the entire Windows system. 

Implementing these troubleshooting steps promptly can prevent further issues and ensure seamless computer operations.
