If your computer experiences a BSOD when loading up, you’ll see a stop code that gives you information on the primary source of the issue. This stop code can vary spending on what caused the error. One of them is the kernel_security_check_failure.

There are several causes for the kernel security check failure, including damaged system files, defective drivers, and malfunctioning hardware. 

You must find solutions quickly to avoid further damage when you encounter this error. This guide will give you several ways to solve the error. 

Let’s begin. 

What is Kernel Security Check Failure?

The BSOD kernel security check failure happens when the Windows operating system discovers a critical problem with the kernel. It’s essential to the operating system to control system resources and ensure stability.

Causes of Kernel Security Check Failure

Below are some of the causes of the kernel security check failure Windows 10:

1. Outdated or Incompatible Drivers

Outdated or incompatible drivers can cause kernel security check failure. Your drivers might not perfectly match your current configuration if you’ve recently updated your operating system or installed new hardware components. So, you should update to the most recent versions.

2. Corrupted System Files

Kernel security check failure Windows 11 may also be triggered by corrupt or damaged system files. Several things, such as failed program updates, malware infections, or conflicts between different software parts, can cause file integrity issues.

3. Faulty RAM

Faulty or failing RAM can cause the “Kernel_security_check_failure” error, which may cause data corruption or system instability. Running a memory diagnostic to identify and fix any memory-related issues is usually the solution.

4. Overclocking

When your PC’s hardware is overclocked improperly or if the hardware can’t handle the increased performance demands, it can cause the kernel security check failure Windows 11.

The key to avoiding this problem is ensuring that overclocking is done properly and that your computer can withstand the higher performance demands.

5. Hardware Issues

Hardware issues, such as a failing hard drive, can also cause Windows 10 kernel security check failure, but they are less common. In such cases, you can exchange the broken hardware parts to regain system stability.

How to Fix Kernel Security Check Failure

Below, we’ll discuss several ways to fix the stop code kernel security check failure. Go through the solutions and find the one that best solves the problem.

Solution 1: Check Your Computer for Memory Problems.

When the Blue Screen of Death (BSOD) error occurs, the root cause may be memory issues. You can use Windows built-in memory diagnostics tool to help discover memory-related issues. Here’s how to do it: 

  • Type “Windows Memory Diagnostic” in the search bar and click on it. 
  • Click “Restart now and check for problems” or “Check for problems the next time I start my computer.
  • Follow the prompts to determine if your PC has memory problems. 

If the diagnostic found memory problems, you can replace the memory card with a new one. Then, check if the Windows 10 kernel security check failure has been resolved.

Solution 2: Check and Fix Hard Drive Errors

The Kernel_security_check_failure might be showing on your screen because of a corrupted or damaged hard disk. The Windows in-built CHKDSK utility can check and repair hard driver errors. 

Here’s how to proceed: 

  • Type “Command Prompt” in the search field, right-click, and select “Run as administrator.” 
  • Enter “CHKDSK C: /f” and press “Enter.” Remember that the “C:” refers to the driver letter of the partition to be scanned. So check your driver and insert the letter accordingly. 

After that, type “exit” and press “Enter” to close the Command Prompt. Then, check if the kernel security check failure Windows 10 has been resolved.

Solution 3: Boot Windows 10 in Safe Mode.

It’s a good idea to try safe mode to see if the Kernel_security_check_failure error goes away. If the error gets fixed in safe mode, your computer’s software may be the cause. In this situation, deleting the program can usually fix the problem.

Here’s how to boot Windows in safe mode: 

  • Press “Windows + I” to launch “Settings.” 
  • Click on “System” and select “Recovery.”

System Recovery Windows 10

  • Click “Restart Now” under “Advanced Startup.
  • When the computer restarts, select “Troubleshoot.”
  • Click on “Advanced options” and select “Startup Settings.”
  • Click on “Restart.”

When the computer restarts, you’ll see several options. Press F4 to start your computer in Safe Mode or F5 to start Safe Mode with Networking. 

You can start searching for any applications that might be causing the stop code kernel security check failure error in Safe Mode.

If the problem doesn’t show, the cause may be from the software. In this situation, you can systematically enable each program again to identify which one is having issues.

You can remove the program if it’s causing the issues.

What Causes BSOD?

BSOD occurs when your computer’s operating system experiences a critical fault from which it can’t recover. Hardware problems like faulty RAM or a failing hard drive, driver conflicts, damaged system files, or even software defects are just a few potential reasons for these errors.

What Is BSOD in a Computer?

BSOD, or Blue Screen of Death, is a critical system error on a Windows operating system computer. The computer’s screen goes blue and frequently displays a detailed error message and a stop code when a BSOD happens. This error message shows that the operating system has run into a problem that it can’t fix and must stop to avoid doing more harm.

How to Check the BSOD Log?

First, press Win + R to open the Run dialog box, and type “eventvwr.msc” to launch the Event Viewer. Expand “Windows Logs” in the Event Viewer and choose “System.” Search for “Event ID” 41. Click the event twice. You can get more information about the BSOD, such as the error code and description.

Where Are BSOD Logs Stored?

The Event Viewer on a Windows PC stores the records for BSOD errors. BSODs are recorded in the Event Viewer’s history of system events, which can help identify and resolve computer problems.
