A Blue Screen error is scary and so when you bump into the Kernel Security Check Failure BSOD error on Windows 10, needless to say, you are concerned. If you come across a BSOD error, you will see a blue screen with an error code – 0x000000139 based on the error.

This means that a certain file has failed the compatibility or integrity check or detects any anomalies in the critical data structure. While the error usually shows up due to outdated drivers and corrupted system files, and also if you are using an outdated Windows version, there are a few other reasons why you may encounter this dreaded error.

Fortunately, the Windows Kernel security check failure stop code is among the common computer errors and can be fixed easily using a few troubleshooting methods.

Common Causes of “Kernel Security Check Failure” Error

There could be different reasons why you may encounter the Kernel Security Check Failure error on the Windows operating system:

  • After waking your PC from sleep
  • Immediately after you insert a new RAM card
  • While playing a game
  • A clash with specific apps and programs
  • Conflicts with recently installed software
  • Memory problems
  • When attacked by a virus
  • Outdated, corrupted, and older versions of the driver
  • Drivers of the previous Win version not compatible with the new Win version
  • Damaged Windows system files
  • When using a previous Windows version that’s outdated
  • A damaged or corrupted hard disk

Now that we know the reasons, let’s check out the fixes.

How to fix kernel security check failure BSOD

Before you proceed with the below fixes, you must try a few basic troubleshooting solutions below to fix the blue screen error, such as

  • performing a system scan for malware and virus infections
  • checking for any pending update on Windows and installing the latest update
  • using a third-party tool to automatically find any outdated or corrupted drives and installing the latest versions automatically

However, make sure you create a backup of the crucial data or files to recover any data which may be lost as you try the kernel security check failure fixes at ease.

Solution 1. Identify memory problems with the memory diagnostics tool

Memory issues can cause a blue screen if the stop code security tests fail. The built-in Windows memory diagnostics tool can help in detecting memory issues. Let’s see how to use the Memory Diagnostic tool on Windows 10:

Step 1. Press the Win + R shortcut key combination to launch the Run command.

Step 2. Type mdsched.exe in the search field and press the Enter key to open the memory diagnostic tool.

kernel security check failure run command

Step 3. This will open the Windows Memory Diagnostic prompt. Here, choose from the options select Restart now and check for problems (recommended) or Check for problems the next time I start my computer.

Step 4. As your PC restarts, Windows will start checking your RAM automatically for memory problems and generate the results. It will indicate the possible reasons why you see the kernel security check failure error. Once you are done checking the memory problems, restart your PC normally and check if the kernel security check issue still persists.

Solution 2. Fix any hard drive errors using the CHKDSK utility

A corrupt hard disk can lead to the kernel security check stopcode due to hard disk errors. To try and fix this issue, select Command Prompt and run the CHKDSK utility. Here’s how:

Step 1. Press the Win + R keys at the same time on your keyboard and the Run command opens.

Step 2. In the Run command window, type cmd in the search field. At the same time, press the Ctrl + Shift + Enter hotkey.

kernel security check failure run command cmd

This will open the window in admin mode.

Step 3. Now run the below command (replace the C: drive with the drive you want to scan) and hit Enter:

CHKDSK C: /f
kernel security check failure run command chkdsk

Now, wait for the scan to detect any errors in the drive’s file system. If found, it will fix the errors automatically. Alternatively, you can run a third-party hard drive tool to repair the hard drive errors.

Solution 3. Disable interfering programs in safe mode

There could be certain programs that may be interfering with the system and causing the error. In this case, boot your Windows PC into safe mode and then check for the interfering apps or software and remove them accordingly:

Step 1. Press the Windows key + R together on the keyboard to open the Run command.

Step 2. In the Run command search bar, type msconfig and press OK.

kernel security check failure run command msconfig

Step 3. This will open the System Configuration window. Here, select the Boot tab and check the box next to Safe boot. Press Apply and OK to confirm.

Step 4. Next, restart your PC to enter into Safe Mode. Now that you are in safe mode, check for the programs that may be causing the kernel security check failure error.

However, if you are unable to boot your PC into the desktop, try to hard boot your PC. Here’s how:

Step 1. Hold down the Power button till your PC shuts down completely.

Step 2. Now, press the Power button again to reboot your PC.

Step 3. Keep repeating Step 2 till you see the PC manufacturer’s logo. You will be redirected to the Windows Recovery Environment.

Step 5. After the scan, if the results show the error message – windows resource protection found corrupt files but was unable to fix some of them, then run the DISM command as below;

DISM /Online/Cleanup-Image/ RestoreHealth

Wait for the scan to get over. It will check the file system and repair the Windows system image automatically.

Frequently asked questions

Some of the questions Windows users usually ask when they bump into the kernel security check failure BSOD error:

How do I know if my kernel is corrupted?

The most common way to know if your kernel is corrupted is if you experience the infamous Blue Screen of Death (BSOD). BSODs are typically triggered when an operating system can’t figure out how to fix a low-level error, and the screen turns blue as a way of indicating that the computer needs to be restarted.
In some cases, BSODs can indicate a more serious problem, such as a hardware failure or a virus infection. However, it’s also possible for BSODs to be caused by relatively benign issues, such as outdated drivers or conflicting software.

Why do I see kernel failure?

When you see the Kernel failure error, it means that the kernel has found corrupt files. There are several reasons this can happen, including a USB error, damage to the file system, or corrupt drivers. In most cases, you can fix the problem by repairing the file system or drivers. However, if the damage is too severe, you may need to reinstall the operating system. In any case, it is important to back up your data before you attempt any repairs, as there is always a risk of data loss when working with corrupted files.

Is kernel security check failure a virus?

Kernel Security Check Failure error message displayed on your Windows 10 screen, does not necessarily mean that your computer is infected with a virus. The message simply means that some data files on your computer are corrupted. The root cause of this data corruption could be due to malware or virus infections, incompatible settings, memory issues, incorrect Registry changes, and more.

How do I fix Windows 10 kernel power 41?

Windows 10 is a complex operating system, and as such, it can sometimes run into problems. One of the most common errors is the “kernel power 41” error, which can cause your computer to crash. There are a few things you can do to try to fix this problem.
First, make sure that all of your drivers are up to date. Out-of-date drivers can often cause stability issues.
Second, duplicate audio drivers to be disabled. Having multiple drivers trying to access the same audio hardware can cause conflicts.

Fourth, modify your power settings. Putting your computer into high performance mode can help to stabilize it. Fifth, turn off Fast Startup. Fast Startup is a feature in Windows that can sometimes cause crashes.
Sixth, BIOS to be updated. A new BIOS can often fix stability issues.
Seventh, verify if you have any damaged or defective hardware, it could be causing your computer to crash.
