A kernel error usually occurs when the kernel detects data corruption. This can be caused by a USB issue, a corrupted driver or a device. Q: Is a kernel security check error fatal? The KERNEL_SECURITY_CHECK_FAILURE error is fatal because it mistakenly causes a blue screen of death.
Kernel security check failure is one of the stop codes you may encounter when your computer receives a Blue Screen of Death (BSOD) error. This stop code indicates that your computer is experiencing memory issues, virus infections, software conflicts, and driver compatibility issues.
The ‘Kernel Security Check Failure’ error can occur for various reasons such as memory problems, virus infections, etc. However, the most common reason is that the drivers you used for the previous version of Windows are not compatible with the new version of Windows. As a result, the operating system issues the error message ‘Kernel Security Check Failure’ followed by error code 0x00000139.
The symptoms of the blue screen problem “KERNEL SECURITY CHECK FAILURE” are a random crash or a crash during the boot process, which makes access to the Windows environment impossible. In my experience, I assume that the above BSOD error is related to hardware or software incompatibility problems.
There are a few things we can do to fix this error.
Force Windows to Full Shutdown
Completely shut down the system to reset Windows at boot time. To do that:
- Click the Power button, hold down the SHIFT key on your keyboard, and then click Shut Down.
- Turn your computer back on.
- Check whether the “BSOD KERNEL SECURITY CHECK FAILURE” problem has been resolved. If this is the case, permanently deactivate the quick start function.

You can now prevent PC problems by using this tool, such as protecting you against file loss and malware. Additionally it is a great way to optimize your computer for maximum performance. The program fixes common errors that might occur on Windows systems with ease - no need for hours of troubleshooting when you have the perfect solution at your fingertips:

Checking hard disk problems
To search for hard disk problems, open the Start menu, click Search, type chkdsk /f C:, and set a disk scan for the next restart of your computer. Make sure you do the right thing before restarting – a hard disk check can take a long time. If you have already taken all necessary precautions and decide to restart immediately, your computer may be unusable for the next few hours depending on the size and speed of your hard disk.
Checking memory space
Remember to check the memory space to make sure it is correctly plugged into the power outlet and functioning properly.
Note: It is always safe to try to replace the memory slot or change the slot where it is connected to the motherboard. Restart your PC to see if the problem persists.
In most cases, one or all of these procedures fixes the Windows 10 kernel security check error. If you know other methods, let us know below!
Check for Corrupted Windows file system
To check if the kernel security scan failed due to a corrupted or corrupted file system, run the System File Checker.
Run this utility if you changed or replaced system files while customizing your operating system. Also run this tool if you think that another program may have changed your system files, although it is unlikely that you are using Windows Vista, 7, 8 or 10. This is because these versions include the System File Checker in Windows Resource Protection, so all critical system files are in protected mode. Even if there is a change, the original file is automatically restored from a cached copy of the folder.
To run this tool, open the command prompt, type “sfc/scannow” and press Enter. This tool runs and if there is a problem, it replaces corrupted cache files during the restart.
