System crashes with Blue screen error “Kernel Security Check Failure” after Windows 11 update, recent hardware change or new software installation? The kernel is responsible for managing system resources, memory, and hardware interactions. When the kernel detects a security violation, such as unauthorized access to memory or data, it triggers kernel_security_check_failure and restarts Windows 11 to prevent potential system instability or data corruption. The most common reason for the stop code is caused by an issue with an outdated driver. Corrupted system files, faulty hardware, and memory module error also trigger kernel security check failure on Windows 11.

kernel security check failure Error
This error usually occurs when a specific data file are corrupt, or one or more of your system files have failed integrity or a compatibility check. Incompatibility between the drivers are the primary reason behind this blue screen error on Windows 11. And you need to update device drivers with the latest version to fix kernel_security_check_failure BSOD.
Again corrupted or damaged file systems trigger this blue screen error, Run built-in tools such as system file checker and DISM restore health command to scan and replace the corrupted files that probably help get rid of this blue screen error.
Problems with memory modules, Faulty hardware components, such as a failing hard drive or overheating components, can also contribute to the kernel security check failure error.
In some cases, Incompatible third-party software or conflicting programs can disrupt the kernel’s operation and trigger the error.
Remove External Devices and Reboot
External devices like USB drives, printers, and external hard drives can sometimes introduce conflicts that lead to BSOD errors, including the “kernel_security_check_failure.” By disconnecting these devices, you eliminate the possibility of their drivers or interactions causing the error.
Let’s first disconnect all external devices connected to your PC (Expact keyboard and mouse) and restart your Device.
It clears temporary glitches, reloads drivers, and can fix issues caused by software hiccups
If the error disappears after removing the external devices, you can then reconnect them one by one to identify which device might be responsible for the issue.
Start windows in Safe Mode
Safe Mode is a diagnostic mode in which Windows starts with only essential drivers and services, excluding unnecessary components. If due to this Blue screen system restarts frequently, start Windows 11 safe mode help isolate whether third-party software or drivers are causing the “Kernel Security Check Failure” error.
You can hold the shift key and restart Windows 11 to access the Windows recovery environment. Or you can boot from installation media and select repair computer.
- Next, select the Troubleshoot option then click on Advanced options.
- On the advanced screen click on Startup settings then restart.
- And finally, click F5 to start Windows 11 safe mode, F6 to enable internet access on safe mode.
If the error does not occur in Safe Mode, it suggests that a third-party software or driver is likely responsible. You can then gradually enable software and drivers in a controlled manner to identify the problematic one.
Update Device Drivers
Problem with the device driver is the primary reason behind this kernel_security_check_failure. Ensure all drivers, especially those for critical hardware components like the graphics card and chipset, are up to date.
- Press Windows + X and select Device Manager.
- Expand the categories and right-click on each device.
- Select Update driver and choose to search automatically for updated driver software.
- Repeat for all critical components like graphics card, chipset, network adapter, etc.
Also, you can Visit the manufacturer’s websites or use Windows Update to find and install the latest drivers.
Check for Memory Issues
If maybe Faulty or unstable memory modules lead to unexpected behaviour, including security violations within the kernel’s operation, which in turn results in the “kernel_security_check_failure” blue screen error. Use Windows Memory Diagnostic to check for memory problems. If issues are detected, consider replacing or troubleshooting your RAM modules.
- Press Windows + R type MdSched and click ok to open the Windows Memory Diagnostic tool.
- Choose Restart now and check for problems.
- Windows will restart and perform a memory test.
It performs various tests to identify memory-related issues like data corruption or faults.
Scan for System File Corruption
Sometimes Corrupted system files can disrupt the proper functioning of the Windows operating system, including its kernel. When critical components of the kernel or other system processes are compromised due to corrupt files, it can trigger errors like the “Kernel Security Check Failure.” Run the System File Checker (SFC) and Deployment Imaging Servicing and Management (DISM) tools to scan and repair corrupted system files that might be causing the error.
- Press the Windows key + S type cmd and Open the Command Prompt as an administrator.
- First, run DISM restore health command DISM /Online /Cleanup-Image /RestoreHealth
- Next, run the system file checker command sfc /scannow
- The above command scan and repairs corrupted system files repairs Windows images and drivers.
- Let the scanning complete 100% and restart Windows 11 to apply the changes.
Check for Hard Drive Issues
A failing or corrupted hard drive can lead to data read/write errors, affecting critical system operations, including those within the kernel. These errors can trigger the “Kernel Security Check Failure” as the operating system’s security mechanisms detect a problem with the data being accessed or written. Use the built-in Windows tools, such as Check Disk (CHKDSK), to scan and repair potential hard drive errors.
- First Open the Command Prompt as an administrator.
- Type the command chkdsk C: /f /r and press Enter.
- Here the /f parameter indicates that chkdsk should fix errors it finds, and the /r parameter tells it to locate and recover readable information from bad sectors.
- Type Y and press the enter key to schedule scan on the next start.
Restart your computer to start scan and fix any disk errors. This process may take some time, depending on the size of the drive and the extent of the issues.
Disable Overclocking
Overclocking involves pushing hardware components, such as the CPU or GPU, beyond their factory-set clock speeds to achieve higher performance. While overclocking can yield performance gains, it can also lead to system instability, especially if not done carefully. If your system is overclocked, revert it to its default settings, as overclocking can lead to instability and trigger the error.
- Restart your computer and enter the BIOS settings by pressing a specific key (usually Del, F2, or F12) during startup.
- Navigate to the overclocking settings and revert to default values.
- Save the changes and exit the BIOS.
Uninstall Problematic Software
If the error started occurring after installing specific software, consider uninstalling or updating the software to eliminate conflicts.
- Press Windows + I to open Settings.
- Go to Apps then installed apps
- Locate the recently installed software causing the error.
- Click on it and select Uninstall.
Perform System Restore
If the error recently started occurring, you can use System Restore to revert your system to a previous state when it was functioning correctly. System Restore allows you to revert your computer’s settings to a previous stable state, undoing recent changes that might have triggered the error.
- Press Windows + S and type Create a restore point and select it
- Click on the System Restore button and follow the on-screen instructions to restore your system to a point before the error occurred.
What is the “Kernel Security Check Failure” error?
- It’s a blue screen error caused by kernel security issues in Windows.
What causes kernel_security_check_failure error?
- Faulty drivers, corrupt files, memory problems, hardware issues, software conflicts, overclocking.
How can I fix the Windows 11 blue screen error?
- Update drivers, check memory, repair files, test hard drives, uninstall problem software, disable overclocking, and try System Restore.
