To scan for malware, use reputable antivirus software. Perform a full system scan and let the software identify and remove any potential threats.

Preventing malware infections is equally important. Avoid visiting suspicious websites and clicking on unknown links. Be cautious when downloading files and only download from trusted sources. Additionally, consider using additional malware removal tools or anti-malware software for added protection.

Check Hardware Connections:

Loose hardware connections can lead to intermittent power supply and result in random restarts. It’s crucial to ensure that all hardware components are properly connected. Check the cables, connectors, and peripherals connected to your computer. Make sure they are securely plugged in and not loose.

Organizing your cables and securing connections can help prevent accidental disconnections. Consider using cable management solutions to keep your cables tidy and prevent them from getting tangled or pulled unintentionally.

Test RAM and Hard Drive:

Faulty RAM or a failing hard drive can also cause random restarts. When the RAM or hard drive encounters errors, it can lead to system instability and unexpected restarts. To test your RAM, you can use built-in memory diagnostics tools or third-party software. These utilities will scan your RAM for errors and provide insights into its health.

Similarly, testing your hard drive can identify any potential issues. Many hard drive manufacturers provide diagnostic tools that you can download and run. These tools will check the health of your hard drive and detect any errors or bad sectors. If either the RAM or hard drive is found to be faulty, it’s important to replace the components to resolve the issue.

Disable Automatic Restart:

Disabling the automatic restart feature in your operating system can be beneficial for troubleshooting purposes. By default, when your computer encounters a critical error, it automatically restarts. Disabling this feature allows you to see any error messages or codes that may be displayed on the screen, providing valuable information about the underlying cause of the random restarts.

To disable automatic restart in Windows, go to the Control Panel, navigate to System and Security, and click on System. Click on “Advanced system settings” on the left-hand side, go to the “Advanced” tab, and click on the “Settings” button under the “Startup and Recovery” section. Uncheck the “Automatically restart” option. In macOS, go to System Preferences, select “Security & Privacy,” click on the “Advanced” button, and uncheck the “Restart automatically if the computer freezes” option.
