To fix your computer from turning off unexpectedly, follow these steps:

1. Check for overheating

Ensure that your computer is not overheating. Clean the air vents and ensure proper airflow. Consider using cooling pads or fans to regulate the temperature. Overheating can trigger automatic shutdowns as a safety measure.

2. Scan for malware

Perform a thorough scan of your computer for malware, as some malicious software can cause sudden shutdowns. Use trusted antivirus software to detect and remove any potential threats.

3. Update your drivers

Outdated or incompatible drivers can cause instability and lead to unexpected shutdowns. Update your drivers regularly by visiting the manufacturer’s website or using automatic driver update software.

4. Check your power settings

Improper power settings can cause your computer to turn off unexpectedly. Make sure your power settings are appropriately configured, preventing automatic shutdowns during idle periods.

5. Verify hardware compatibility

Ensure that all your hardware components are compatible with your operating system and motherboard. Incompatible hardware can cause sudden shutdowns or other stability issues.

6. Run a system file check

Perform a system file check to scan and repair any corrupted or damaged system files. Open the command prompt as an administrator and run the “sfc /scannow” command.

7. Update your BIOS

An outdated BIOS can cause stability issues. Visit your motherboard manufacturer’s website to check for the latest BIOS version and update it accordingly.

8. Check your PSU

A failing or insufficient power supply unit (PSU) can lead to unexpected shutdowns. Ensure your PSU is in good condition or consider replacing it if necessary.

9. Disable automatic restart

Disable the “automatic restart” feature to prevent your computer from restarting immediately after a shutdown. It allows you to observe any error messages that may provide insights into the issue.

10. Check for software conflicts

Conflicts between software programs can cause your computer to turn off unexpectedly. Uninstall any recently installed software or updates to see if the problem persists.

11. Test your RAM

Faulty RAM modules can cause system instability and abrupt shutdowns. Use a memory testing tool to check for any issues and replace or reseat the RAM as needed.

12. Seek professional assistance

If all else fails, it may be best to consult a professional computer technician who can diagnose and repair any hardware or software issues causing the unexpected shutdowns.
