How to fix “Kernel Security Check Failure” error in Windows 10

The “blue screen of death”, also known as BSOD, is familiar to every Windows user. Errors occur under various conditions, at the time of launching the operating system or during operation and are accompanied by a message with a code. At the same time, the text of the notification does not contain exhaustive information on how to act in this situation, but the majority of users are not the first to deal with the problem on their own, trying one by one existing methods of correction. Such errors can occur for various reasons, and the system is not always able to cope with the task of eliminating the failure. So, in the case of Kernel Security Check Failure, mandatory user intervention is required, because the problem does not solve itself. The error is often accompanied by the code 0x00000139, the blue screen may also not show its full name, which in fact does not change the situation.

Troubleshooting Kernel Security Check Failure.

Causes of error

This problem may occur both at boot time and some time after switching on. In addition, the failure is unpredictable and may not even manifest itself for several days, after which it will remind of itself again. Knowing exactly how to troubleshoot is possible only if the cause is known, but since there are a number of provoking factors, in most cases you have to identify the source of the problem by trying to correct the situation. The Kernel Security Check Failure error, typical for Windows 10 and other versions, often appears for the following reasons:

  • Damage to the system files.
  • Irrelevant or missing drivers.
  • Outdated BIOS version conflicting with other software.
  • Other software conflicts.
  • Damage / no registry entries.
  • Overheating of the processor, video adapter.
  • Incompatibility of components in the PC assembly.
  • Other hardware faults.

The reasons are possible and others, in each case there is a possibility that the failure is triggered by another factor and it is not often possible to expose the source of the trouble.

How To Fix Kernel Security Check Failure Error

We will consider effective methods for solving problems, in most cases coping with the elimination of this failure.

Hard disk check

It is possible to test the hard drive for errors with the help of the integrated system tool CHKDSK (Check Disk). To use it, you need to open the command prompt on the administrator’s rights via the Run (Win + R) console, enter the cmd command in the field, then press Ctrl + Shift + Enter. The same can be done by searching the Start menu (in the output results for a query, press RMB on the service to open the context menu, where we select the appropriate mode for launching the tool). We start scanning the hard disk:

  • At the command prompt, enter the command chkdsk C: / f.
  • The f key in the command involves checking for errors and automatically correcting them if detected. Section C will be checked, since, as a rule, it is a system partition. If the OS is on a different disk, change the value.
  • At the subsequent system start, the service will start checking, we expect it to finish (the process will take some time, which depends on the size of your disk), after which you will see the results of the procedure.

When installing multiple hard drives, you will need to check each one at a time. After scanning, we reboot the device and check if the Kernel Security Check Failure error is fixed.

System File Checker

Error Kernel Security Check Failure in Windows 8 and 10 often occurs due to damage to system data. Despite all the fixes made by Microsoft developers, which are regularly supplied as service packs, they do not save those users who install them. To scan the data and automatically correct the detected errors, use the System File Checker (SFC) utility. The tool is launched from the command line as an administrator using the Run console or the Start button. If the operating system does not boot, you can access using the installation flash drive (disk) with the appropriate version of Windows. So, we perform scanning and recovery of OS files:

  • Run the command prompt as administrator.
  • Enter the sfc / scannow command and press Enter.
  • We are waiting for the completion of the process, which will take some time.
  • The utility will scan the data and identify existing problems, as well as restore the necessary files, if possible. For the user, a report will be generated at the end of the process.

Scanning system files is one of the first steps to take when a Kernel Security Check Failure fails. In many cases, the built-in service solves the problem and more serious procedures are not required, but if it did not help, it means that the source of the failure is in another place and you need to try other correction methods.

Testing RAM

A blue screen with an error Kernel Security Check Failure may appear when there are problems with RAM, which is especially important when there are several RAM bars on a computer. To check which one of them causes a failure, you need to extract everything and leave on the motherboard one line at a time, while observing if an error occurs. If a problem strap is detected, it is better to replace it. For testing RAM in Windows, there is also a built-in tool. You can go to it, for example, using the search box where you need to enter the query "Windows Memory Checker". After opening the application, select the test option. You can test memory using third-party products. Well-known utility Memtest86 +.

Elimination of registry changes

Often, system failures occur due to incorrect registry entries, not an exception error code 0x00000139. Change the record could programs, viruses, or the user himself by negligence or intentionally. Insignificant at first glance, adjustments can lead to unpleasant consequences, and the blue screen is not the worst possible problem. To determine whether the Kernel Security Check Failure error in Windows 10 is related to registry changes, you can restore it to a valid version from a backup. If it is not available, it is better to edit the records using specialized software, for example, using the CCleaner utility, which will scan and fix the detected problems.

Driver problems

The reason why the error code 0x00000139 occurs may be irrelevant drivers or a conflict between the installed software and the operating system. Then you need to update inappropriate drivers of installed components to the latest versions. You can download them from the official site of the device manufacturer (video card, motherboard, etc.), then in the “Device Manager” in turn for each of the objects, press the RMB and select the driver option from the action menu to update the driver. To simplify the task, you can use a special software that allows you to perform the procedure in automatic mode. If the error occurred after installing a new component, a software conflict with the operating system may have occurred. Incompatibility of equipment as a result of inconsistency of parameters is a common problem, so when assembling it is necessary to pay attention to the technical characteristics of devices. For the treatment of Kernel Security Check Failure update will require not only drivers, but also the BIOS. Replace the outdated version of the current one by applying the software of the manufacturer of the motherboard. The “blue screen” can also be triggered by the critical temperatures of the devices, so it would not be superfluous to check the processor, video card and hard disks manually or using special programs.

The above methods are quite effective in solving the error code 0х00000139, but if none of them helped you, you will have to take extreme measures and reinstall the system.
