The “Kernel Security Check Failure” error is a Stop Error or Blue Screen of Death (BSOD) that users may encounter due to various underlying problems. This error signifies that the system has detected data corruption, particularly within its kernel data. Such corruption can arise from several sources, ranging from faulty hardware to corrupted system files or outdated drivers. 

Addressing this error requires a systematic approach to identify its root cause and then apply appropriate solutions. In this article, we’ll explore the base of the problem and explain its solutions to troubleshoot and rectify the issue.

Causes of the Error

The “Kernel Security Check Failure” error in Windows 10 can be triggered by a variety of factors and understanding these causes can be instrumental in effective troubleshooting:

Corrupted System Files: Over time or due to malware attacks, crucial system files can become corrupted, preventing them from functioning correctly and leading to this error.

Outdated or Incompatible Drivers: Drivers facilitate interaction among operating system and the hardware, whereas, Outdated, incompatible, or corrupted drivers can create conflicts, triggering the error.

Faulty Memory (RAM): Defective RAM modules can cause data corruption, which the kernel detects, resulting in the error.

Hard Disk Errors: Bad sectors, corrupted partitions, or issues with the hard disk’s functionality can cause data inconsistencies that the system’s kernel identifies as a threat.

Software Conflicts: Some software, especially those that require deep system access, can conflict with Windows processes. Such conflicts can prompt the kernel security check to fail.

External Hardware Issues: Sometimes, external devices, when connected to the system, can cause conflicts or issues, especially if their drivers are outdated or incompatible.

Overclocking: Pushing your CPU or GPU beyond its specifications can sometimes destabilize the system, leading to various errors, including kernel security check failure.

Understanding these causes provides a foundation for the troubleshooting process, guiding users toward effective solutions tailored to their specific situations.

Troubleshooting the Error

To address the “Kernel Security Check Failure” error in Windows 10, it’s essential to approach the issue methodically. Here’s a systematic breakdown of steps to pinpoint and resolve the problem:

1: Update Windows 

Microsoft frequently releases patches and updates that rectify known issues. Ensure your Windows OS is updated to its latest version.

2: Disconnect External Hardware 

Remove any recently added components such as external hard disks, printers, or USB and check if the error persists. If it doesn’t, again start connecting these devices to identify the problematic device.

3: Check for Corrupt Files 

Use the built-in tool to scan and fix corrupted system files. To do this:

  • Open Command Prompt from the system and click on the Run as administrator:
  • After that, simply type and execute the sfc /scannow command and press Enter:
  • Allow the process to complete and follow on-screen instructions.

4: Update Drivers 

Outdated or corrupted drivers can be a primary cause.

  • Access the Device Manager:
  • Update drivers, especially for components like graphics cards, network adapters, and hard drives:

5: Memory Diagnostic 

To verify if faulty RAM is the issue:

  • Type “Windows Memory Diagnostic” in the Windows search bar and select the application:
  • Follow prompts to check for memory issues:

6: Disk Check 

Inspect your hard drive for errors:

  • Again open the Windows terminal from the local system:
  • Type chkdsk C: /f /r command and execute it by hitting enter after replacing ‘C:’ with the appropriate drive letter if needed:
  • Follow any instructions to schedule or run the disk check.

7: System Restore 

If you’ve recently made significant changes to the system or installed new software, reverting to a previous state might help:

  • Type “System Restore” in the search bar and follow the prompts:
  • Choose a restore point from before the error began occurring:

8: Reset Your PC 

If all else fails, consider resetting Windows 10. This will reinstall Windows, so ensure you’ve backed up important data.

  • Go to Settings > Update & Security > Recovery:
  • Under “Reset this PC,” select “Get started” and follow the on-screen steps:

Approaching the error with these steps ensures a comprehensive examination of potential issues, allowing for effective problem resolution.

Preventing the Error in the Future

before getting an error it is important to stay away form the problems using the following tasks:

Regular System Maintenance: Keep your city (system) clean and organized. Regular checks can prevent many issues.

Keeping Your System Updated: Like ensuring your city’s infrastructure is up-to-date, keeping Windows and drivers updated is essential.

Using Trusted Software: Only install software from sources you trust and it’s like not inviting strangers into your home.

Understanding the Importance of Backups: In the unpredictable world of tech, always have a plan B.


The “Kernel Security Check Failure” error can be daunting, but having the right tools with their knowledge, it’s a hurdle you can clear. Like navigating a complex maze, knowing the paths can help you find the way out. Stay patient, stay curious, and always keep learning.
