Way 4. Scan & Repair Hard Disk Corruption

Hard disk corruption can also lead to BSOD errors like the Kernel Security Check Failure. We'll explore automated and manual methods to scan and repair potential hard disk issues.

A. Using EaseUS Partition Master (Automated)

EaseUS Partition Master can quickly check and repair hard disk errors. The intuitive interface makes it easy to use, even for non-technical users.

B. Run the CHKDSK commands (Manual)

The CHKDSK utility can repair hard drive errors and is a useful tool in Windows 10. However, for users who are not familiar with commands, they are prone to mistaken operations. In this case, I suggest users use EaseUS Partition Master to automate the process.

When using the CHKDSK utility, two essential parameters can help identify and resolve hard drive problems:

• The "/f" parameter instructs the tool to scan the drive, detect errors, and automatically repair them.
• The "/r" parameter directs the utility to identify bad sectors of the drive and attempt to retrieve any readable data from them.

Here's how to execute CHKDSK commands:

Step 1. Launch and run Command Prompt as administrator.

Step 2. Type the command CHKDSK [drive letter]: /f (replace [drive letter] with the letter of the target partition) and press Enter.

Step 3. Once the process is done, type exit and press Enter to quit the Command Prompt utility.

Way 5. Check File System

File system corruption can also contribute to BSOD errors such as the Kernel Security Check Failure. You have two options for fixing file system issues: using EaseUS Partition Master for an automated solution or running Scannow Commands manually.

A: EaseUS Partition Master (Automated)

EaseUS Partition Master offers automated file system checks and repairs. It simplifies the process of scanning and fixing file system issues without requiring in-depth technical knowledge. This tool can help identify and correct errors efficiently, ensuring your system runs smoothly.

Follow the steps:

Step 1. Right-click the target partition that has a problem.

Step 2. Choose "Advanced" > "Check File System".

Step 3. Confirm if you want to hide the partition or not.

Step 4. In the Check File System window, check the "Try to fix errors if found" option.

Step 5. Click "Start" to check errors on your partition.

B. Run Scannow Commands (Manual)

For users who are comfortable with the command line, the built-in System File Checker (SFC) tool can be used to scan and repair file system corruption.

Follow the steps:

Step 1. Restart your computer and interrupt the boot process (often F11/F12) to enter Advanced Startup Options.

Step 2. Navigate through "Troubleshoot" > "Advanced options" and choose "Startup Settings" followed by a restart with those settings enabled.

Step 3. In the boot options screen, select "Enable Safe Mode with Command Prompt."

Step 4. Once in Safe Mode, search for "Command Prompt," right-click, and select "Run as administrator."

Step 5. Type SFC /scannow and hit Enter to initiate the SFC scan. After the scan finishes, type Exit to close the Command Prompt.

Step 6. Exit Safe Mode and go back to the normal Windows interface.

Step 7. Search for "Windows Memory Diagnostic" and choose "Restart now and check for problems."

Step 8. The system will reboot and run a memory test. Check the results after the test is complete.

Way 6. Update Device Drivers

Outdated or incompatible device drivers often lead to issues like the Kernel Security Check Failure error. Updating your drivers potentially resolves compatibility issues and restores system stability.

Follow the steps:

Step 1. Open Device Manager by pressing Win + X and selecting "Device Manager."

Step 2. Expand the categories (e.g., Display Adapters, Network Adapters) to view your hardware devices.

Step 3. Right-click the device and select "Update driver."

Step 4. Choose "Search automatically for updated driver software" and refer to the on-screen steps.

Way 7. Check for the Malware or Viruses

Malware or viruses can cause significant system instability and errors, such as the Kernel Security Check Failure. Running a thorough system scan will help detect and remove malicious software that may be causing the problem.

Follow the steps:

Step 1. Search "Virus & threat protection" in the search bar and click on it to open it.

Step 2. Click on "Scan options" under "Quick scan."

Step 3. Select "Full scan" and then click "Scan now."

Step 4. Let your PC scan completely and detect malware or viruses.

Way 8. Restore or Reinstall Windows

When other methods do not resolve the issue, restoring or reinstalling Windows potentially fixes kernel security check failure. Be sure to back up your data before restoring or reinstalling Windows, as you may lose your data during both procedures.

Here's how to restore Windows 10:

Step 1. Press Win+I to open Windows Settings.

Step 2. In the Settings window, navigate to the Update & Security section and click on Recovery.

Step 3. Under the Reset, this PC section, click on the Get Started button.

Step 6. Review the additional settings and click Next.

Step 7. Finally, confirm that you want to reset your Windows installation by clicking Reset PC.
