Experiencing random restarts on Windows 11 can be frustrating and disruptive. This problem can happen due to various reasons, from hardware issues to software conflicts. Fortunately, there are several straightforward steps you can take to identify and fix the problem.

In this guide, we will walk you through effective and easy-to-follow methods to stop your Windows 11 from restarting unexpectedly. Each step is explained clearly to help even beginners understand and apply the solutions.

By following these tips, you can save time and avoid unnecessary frustration. Let’s get started with some quick checks before diving into detailed troubleshooting.

These steps will help you restore stability to your system and improve your overall Windows 11 experience.

Quick Note: Preliminary Checks Before Troubleshooting

Check Power Supply: Make sure your PC or laptop is plugged in correctly, and the power cable or battery is working fine.
Note Any Recent Changes: Think about any new software, hardware, or updates installed before the restarts began.
Backup Important Data: Always create a backup of your important files before making significant system changes to avoid data loss.
Ensure Windows is Updated: Sometimes, Microsoft releases patches that fix bugs causing restarts. Check for updates via Settings > Windows Update.

Step 1: Disable Automatic Restart to Diagnose the Issue

When Windows encounters a serious error, it may restart automatically without showing the error message. Disabling this feature helps you see the error message, which is crucial for identifying the cause.

Press Windows + R to open the Run dialog.
Type sysdm.cpl and press Enter.
In the System Properties window, go to the Advanced tab.
Under Startup and Recovery, click Settings.
Uncheck the box next to Automatically restart under System failure.
Click OK and restart your computer.

Now, if your PC crashes again, it will show an error message or blue screen instead of restarting immediately. Use this information for further troubleshooting.

Step 2: Run Windows Troubleshooter for Hardware and Devices

Windows 11 has built-in troubleshooters that can automatically find and fix common problems. Running the hardware troubleshooter can detect if any connected device is causing restarts.

Open Settings by pressing Windows + I.
Navigate to System > Troubleshoot > Other troubleshooters.
Find Hardware and Devices and click Run.
Follow the on-screen instructions to complete the process.

This tool helps identify hardware-related problems that might be causing your PC to reboot unexpectedly.

Step 3: Check for Driver Issues and Update Drivers

Outdated or faulty drivers can cause instability and random restarts. Keeping your drivers up to date ensures compatibility with Windows 11 and smooth system operation.

Right-click the Start button and choose Device Manager.
Look for any devices with a yellow exclamation mark, which indicates a problem.
Right-click the problematic device and select Update driver.
Choose Search automatically for drivers to let Windows find the latest version.
Repeat this for critical components like display adapters and network adapters.

Alternatively, you can visit the manufacturer’s website to download the latest drivers manually.

Step 4: Scan for Malware and Run System File Checker

Malware infections and corrupted system files are common causes of random restarts. Running a full virus scan and repairing system files can help fix these issues.

Open Windows Security by searching in the Start menu.
Go to Virus & threat protection and run a Full scan.
After the scan completes, open Command Prompt as an administrator (search for cmd, right-click, and choose Run as administrator).
Type the following command and press Enter:
sfc /scannow
Wait for the process to finish. It will automatically repair corrupted files if any are found.

Step 5: Adjust Power Settings to Prevent Unexpected Restarts

Incorrect power settings can cause your system to restart randomly, especially on laptops. Modifying these settings can improve stability.

Press Windows + R, type control, and press Enter to open Control Panel.
Go to Hardware and Sound > Power Options.
Click on Change plan settings next to your selected power plan.
Choose Change advanced power settings.
Expand Processor power management and then Minimum processor state.
Set both On battery and Plugged in to 5% or higher.
Click OK to save changes.

This prevents the processor from throttling too aggressively, which can sometimes cause restarts.

Step 6: Check for Overheating and Hardware Issues

Overheating is a frequent causes of unexpected restarts. Your system may restart automatically to protect hardware from damage.

Feel the temperature: Check if your PC or laptop feels very hot.
Clean air vents: Dust buildup can block airflow, so use compressed air to clean vents and fans.
Use monitoring software: Tools like HWMonitor or Core Temp can track your CPU and GPU temperatures.
Test hardware: Faulty RAM or power supply units (PSU) can cause restarts. Use Windows Memory Diagnostic by typing it in the Start menu and running the test.

If overheating or hardware faults are detected, consider professional cleaning, replacement, or repair.

Step 7: Update Windows and BIOS Firmware

Keeping Windows and BIOS updated is important because updates often include fixes for bugs and compatibility issues.

Go to Settings > Windows Update and click Check for updates.
Install all available updates and restart your PC.
To update BIOS, visit your motherboard or PC manufacturer’s website.
Download the latest BIOS firmware and follow the official instructions carefully. Updating BIOS incorrectly can damage your system, so proceed with caution.
