The Blue Screen of Death error can shut down your PC without warning. When a BSOD appears, you are more likely to lose all unsaved work.

Many users have complained of Kernel security check failure BSOD error.  If you are looking for solution to this BSOD error, this post is for you.

Here we have provided four solutions that could fix the issue.

Since there can be several reasons behind this BSOD, it is difficult to tell which solution will work for you.  You can start with the first solution and if it does not work for you, move to next solution and so on.

Solution One- Undo Any Recent Changes

Try to recall when Kernel security check failure BSOD error started appearing. Did you install any hardware or software recently? Did you make any changes to Windows settings?  If you did, undo any recent changes and see if the issue is resolved.

Solution Two- Update Drivers

A large number of BSOD are related to drivers and the Kernel security failure in your case may well be occurring because of some driver-related issue.

According to some experts, Kernel security check failure is related to display adapter driver.

A simple solution to this problem is updating display drivers.  There are two methods to update display drivers – Manual and Automatic.

Here we have provided both ways to update drivers.

Method One- Update Drivers Manually

• Press Windows logo key and R simultaneously on the keyboard to invoke Run command box
• In the Run command box, type devmgmt.msc and hit Enter on the keyboard
• In the Device Manager window, go to Display adapter category and expand it
• Right-click on the Display adapter and click Properties

• In the properties window, go to General tab
• Note down the name of the Display adapter, manufacturer name, and other details
• Now go to Driver tab and note down the driver version

• Close Device Manager
• Open Internet browser
• Go to Display adapter manufacturer website and type the name of the display adapter in search box.
• You will see the list of downloads available for display adapter. You need to be careful when downloading display adapter drivers. For example, if your computer has Windows 32-bit OS installed, you need to download and install 32-bit display adapter drivers. Similarly, if you have 64-bit OS, you need to download 62-bit display adapter drivers.
• Make sure you download the latest display adapter driver version. For example, if you have display driver version 21.21.13.4201 installed, you need look for higher version of the driver.
• After the latest display adapter drivers are downloaded, double-click on the setup (.exe) file and follow on-screen instructions to install network drivers. If the driver setup file is in .zip format, unzip the file contents to a folder and then double-click on the setup(.exe file)
• Restart PC after installing display adapter drivers

Run your computer and see if the Kernel security check failure BSOD appears on the screen.  If the issue remains unresolved, move to next solution.

If you feel the method of manually updating drivers is cumbersome, you can consider updating drivers automatically.

Method Two- Update Drivers Automatically

Automatic driver update tools offer many benefits, the most important ones being:

• You can update device drivers automatically
• The software scans and updates all outdated or missing drivers at one go
• The tool picks the right drivers for your device and operating system, so you won’t have to worry about installing an incorrect driver by mistake
• Automatic driver updates are 100% safe

Driver Updater is one of the best driver update tools out there. Outbyte Driver Updater will give you access to a database of over 1 million drivers. It will regularly scan your PC, suggesting new driver versions to install. Driver Updater contains drivers for a variety of Windows devices. With just one click, you can update drivers in your system.

Solution Three – Check Memory

There is a possibility some memory fault is the cause behind the Kernel security check failure.

You need to check the memory slots and also check the RAM modules for any problem.

The troubleshooting steps in this solution are divided into two sections. Here are the steps to follow.

Step One – Check Memory Slot

Make sure the RAM module is placed firmly in the socket and it is functioning correctly.

To ensure there is no problem with memory slot, insert the RAM module in a different memory slot on the motherboard.

After you have confirmed there is no problem with memory slot, you need to check the RAM modules for any faults

Step Two – Run Memtest

Windows has an in-built memory diagnostic tool that scans RAM for any faults and reports any error it finds.

Here are the steps to follow.

• Press Windows logo key and R button together on the keyboard to access Run command console
• In the Run command window, type mdsched.exe

• You will see two options- 1) Restart now and check for problems (recommended) and 2) Check for problems the next time I start my computer.

• If you want to immediately run Memtest, select option one else select option two
• If you have selected the first option, the computer will restart and you will see Windows Memory Diagnostic tool in action checking RAM module for any faults

• If you select the second option, the Windows Memory Diagnostic tool would run when the computer reboots next time.

If Memtest comes across any faults, it will report an error.

If Memtest completes without reporting any error, you can draw a conclusion the RAM modules are in good condition.

Start the PC and see if the issue is resolved. If the issue remains unresolved, try next solution.

Solution Four – Check Hard drive for any errors

With time hard drive sectors can go bad and this in turn results in corruption of NTFS volume and file system.

When that happens, Windows can’t access files it need to run the operating system normally.

Windows has a disk check and repair tool known as Chkdsk. It checks the file system and file system metadata of a volume for logical and physical errors.

Chkdsk is a command-line tool and you need to run the command from a command prompt window (with admin rights).

Here are the steps to follow.

• For Windows 10 users – Click Start and type cmd prompt in Cortana Search
• For Windows 7 users – type cmd prompt in search box
• Right-click on Command prompt from the list of results and select Run as administrator
• In the command prompt window, type chkdsk /f /r.

• Hit enter on the keyboard
• Windows will prompt you question about scheduling chkdsk at next restart. Type Y for an answer
• Press Enter on the keyboard
• Windows will run Chkdsk tool at next restart. The tool will report any errors it comes across and fix them

Note – you need to be patient and wait until process is completed. Chkdsk can take a longer time to complete and it depends on the capacity of the hard drive.

• After the Chkdsk complete its operation, the system will reboot

Boot into Windows and see if you encounter “Kernel Security Check Failure” BSOD error again.

In most cases, the “Kernel Security Check Failure” BSOD error would get resolved by one of the solutions given in this post.
