9 Possible Fixes For Kernel Security Check Failure Issue


One of the most dreaded sights for computer users is what is commonly called the Blue screen of death. When the computer screen goes blue, with an error message, you know things are really out of hand. The kernel security check failure is one of the causes of the blue screen of death.

This article will introduce you to what the Kernel security check failure is, what its causes are, and finally, what you can do to fix the problem.

What Is The Kernel Security Check Failure

You’re probably reading this article because you have experienced the Kernel security check failure—or someone you know has. The blue screen of death signals the error.

The error message comes suddenly and effectively shuts down the computer. This is done to prevent further damage that could occur if the error isn’t fixed suddenly. 

Some situations in which people have reported experiencing the Kernel security check failure include:

  • After waking up from the computer from sleep
  • After a RAM upgrade
  • While playing a game, and
  • While using a particular app.

So what exactly does the kernel security check failure mean? It means one or more files have failed a compatibility or integrity check. Though the error message does not point out what files are defective, your best bet at resolving the problem is by locating those files.

Causes Of The Kernel Security Check Failure

Many factors can lead to kernel security check failure. Some of the most common reasons for the blue screen of death are discussed briefly.

Incompatible drivers 

This is the most common cause of kernel security check failure. If you have recently upgraded from windows 8 to 10, it’s possible some of the drivers are not compatible with OS. The same also applies if you recently installed or upgraded drivers.

Outdated drivers

 If your drivers need an upgrade, it can lead to kernel security check failure.

Corrupted Windows system files

This can also happen during upgrades. Duplicates or invalid files may be created that cause errors.

Memory problems

If you have a small memory size, it can cause the computer to misbehave. There are also problems with having RAM in need of an upgrade. This is also true if any hardware is damaged or improperly fixed.

Damaged or corrupted hard disk 

If the hard disk is not fixed properly or is damaged, it can lead to serious problems.


This is also a common cause of problems with computers. Viruses can also lead to any of the problems on this list.

Troubleshooting Kernel Security Check Failure

Now we know what kernel security check failure is and what the major causes of the failure are, we can now dive into solving the problem. These fixes work if the underlying problem they are meant to address is the cause of the kernel security check failure.

So a solution that involves you changing the harddisk only works of the harddisk is the cause of the kernel failure. With that in mind, let’s dive into the fixes for the kernel security check failure.

1. Use System File Checker and Memory Diagnostic

Using this diagnostic tool helps you find out what specific files are defective, and repair the damage. Here is how to go about using the file checker for diagnosis.

Go to Settings, go to Advanced option then select Startup settings

Click the restart button on the lower right side of the screen. This will make the OS startup with minimal system requirements

Select the Restart option when it appears on the screen. Select Enable safe mode with network.

5. Check Disk For Error

Using the command prompt you can check the hard disk for errors. This helps you identify where exactly the source of the error is. These are the steps involved in checking the disk for errors.

Open the start menu and use the search feature to search for the command prompt.

Right-click on the command prompt and select Run as administrator.

When the command prompt interface opens, type the command: chkdsk C:/f, and press enter.

Note that the letter C should be changed to the letter of the hard drive partition on your computer.

Run the command chkdsk C:/r also.

This is a time-consuming process that can take between 30 minutes and two hours depending on the size of the disk. 

Note also that the /f makes sure the file is fixed. If it isn’t added the message will be displayed that the file needs to be fixed without actually fixing it.

/f resolves logical issues with the drive while /r resolves physical issues.

6. Check Memory Slots

Memory problems also cause the kernel security check failure. If the memory slots are not properly fixed or connected, it can lead to this error. Check if the memory slot is properly placed in the socket. 

If the slot is damaged, you can replace the memory slot or change the slot in which it is plugged into the motherboard. After checking the memory slots, restart the computer.

7. Check Hard Drive 

Check if the hard drive is plugged correctly. If you are sure it is plugged correctly, restart your computer and see if the error persists. If the error persists it is also possible the hard drive needs to be changed.

If you have a spare replace it and see if it solves the problem of kernel security check failure.

8. Update Windows

A Windows update usually solves many problems. During the update, many bugs and defects in the previous version are repaired. Furthermore, software and system applications that have problems are automatically repaired.

Search for Updates on the search bar and follow all the prompts to update Windows.

9. Scan For Virus

Running a virus scan is a good way to find defective files and applications. The antivirus also helps to repair or delete files that are a threat.

10. Delete Software

Deleting software is particularly useful if the problem started after a recent software installation. Instead of consisting of a full system reset, you delete the software most recently installed.


The blue screen of death is a sign that there are problems that need to be resolved. One problem that can cause the blue screen of death is the kernel security check failure. This article has explained the various methods of solving that error. Hope it helps you to fix this error.
