Your Step-by-Step Guide to Fix Random Restarts on Windows Computers

Experiencing random restarts on your Windows computer can be both frustrating and disruptive. This guide provides a comprehensive set of actionable solutions to tackle the problem effectively.

Step 1: Start with Basic Solutions

Before delving into more complex troubleshooting methods, take the time to implement some fundamental solutions:

Step 1.1: Examine Your Power Outlet

Ensure there are no loose connections or issues with your power outlet. Test your PC’s connection with another outlet to confirm it is secure.
Step 1.2: Ensure Your PC Isn’t Overheating

Overheating can cause sudden restarts. Ensure your machine is well-cooled and not performing resource-intensive tasks without adequate cooling.
Step 1.3: Clean Your Computer Components

Dust accumulation can lead to overheating. Safely clean internal components or seek professional service if needed.

Step 2: Disable Automatic Restart on System Failure

Windows has a feature that causes it to restart automatically when a failure occurs. Disabling this can help you understand the root cause of the problem. Follow the steps below:

Step 2.1: Open Windows Settings

Use Windows Key + I to access the settings, then go to System > About
Step 2.2: Access Advanced System Settings

Click on Advanced system settings.
Step 2.3: Configure Startup and Recovery Settings

In the Advanced tab, click the Settings button under Startup and Recovery.
Step 2.4: Uncheck Automatic Restart

Uncheck the box for Automatically restart and click OK.

Step 3: Inspect Loose Internal Connections

Open your computer case to check for any loose cables or components that may have shifted during transport. If you’ve added new hardware recently, ensure it’s compatible and correctly installed.

Step 4: Analyze Your Power Supply

Ensure your Power Supply Unit (PSU) can handle the load of all your hardware, especially under high-performance tasks. A malfunctioning PSU can lead to power shortages and unexpected restarts.

Step 5: Adjust Power Plan Settings

Adjust your power settings to ensure your computer operates in high performance mode instead of the power-saving mode, which may lead to unintended restarts.

Step 6: Check Your Laptop’s Battery

If your laptop battery is faulty or poorly connected, it may cause sudden restarts. Consider replacing if it’s not performing well.

Step 7: Remove Recent Software Installations

Identify any recent software installations that could be causing conflicts and uninstall them to test if stability returns.

Step 8: Conduct a Malware Scan

Malware can cause erratic behavior in your system, including restarts. Use your antivirus or Windows Security to perform a comprehensive scan.

Step 9: Perform a Windows Update

Check for and install any available Windows updates. These updates can address known bugs that may result in crashes.

Step 10: Cease CPU Overclocking

Revert any overclocking settings to prevent overheating and ensure stability.

Step 11: Run the Memory Diagnostic Tool

This tool can help identify issues with your RAM that may contribute to unexpected restarts. Follow the prompts to perform a memory check.

Step 12: Execute SFC and DISM Scans

Utilize the SFC and DISM commands to repair corrupt system files that may cause instability.

Step 13: Keep Your Drivers Updated

Outdated or corrupt drivers can lead to various issues, including restarts. Use the Device Manager to ensure all your drivers are up to date.

Step 14: Turn Off Fast Startup

Disabling Fast Startup may alleviate boot issues that lead to random restarts.

Step 15: Upgrade Your BIOS

A BIOS update can resolve compatibility issues and improve system stability but be cautious during this process.

Step 16: Reinstall Windows as a Last Resort

If all else fails, consider reinstalling Windows to eliminate software-related restart issues.

Conclusion

Experiencing random restarts on your Windows computer is indeed frustrating. By following the actionable steps laid out in this guide, you should be well on your way to mitigating this problem and ensuring a stable workstation.
