Kernel Security Check Failure

If you have opened this link and got to this article, it clearly indicates that you have encountered the BSOD, namely Blue Screen Of Death.

Luckily for you, reading this article will help you to get an idea about the causes which led to this error. The main agenda of this article is to help you resolve the “Kernel Security Check failure” BSOD on Windows 8.1 and Windows 10.

The ‘Kernel Security Check Failure‘ PC error can happen for several causes such as memory problems, virus infections, and many more. But then, the most popular cause is that driver which you were using with your earlier Windows version is not compatible with the one which just happened to upgrade to. Due to this, your Operating System starts sending you the ‘Kernel Security Check Failure’ error message on the Blue Screen Of Death (BSOD), which is followed by the 0x000000139 error code.

The driver's compatibility issue is not the only reason because of which the irritating Kernel Security Check Failure error occurs. There are other various reasons why this could happen. Those reasons as following:

1. Kernel Security Check Failure after sleep —More than a few users have complained about this error occurring after they tried waking their PC from sleep.

Solution 3 — Check the memory slot

You should make sure that you checked the memory slot to verify whether it’s accurately fixed into the holder and working perfectly.

Note: It is always a secure gamble to examine and renew the memory slot or replace the slot in which it is plugged into the motherboard. Restart your computer to check whether the problem still exists or not.

Solution 4 — Check your hard drive

Be sure that your hard drive works perfectly. More particularly, verify twice that it is plugged in precisely into your device. If you own an extra hard drive, try replacing it to check if it starts accurately.

At this point in time, if your operating system begins and is only giving you this Kernel Security Check Failure error sometimes, you will have to follow the steps mentioned below:

Now, part two of this article. If your operating system starts and only gives you this Kernel Security Check Failure error occasionally, follow the steps below:

Solution 1 — Update your PC

You need to make sure that you are using the updated and the latest Windows Operating System updates on your computer. Let me just remind you once again, Microsoft regularly rolls out Windows updates so as to enhance the system’s endurance and resolves several problems.

To open the Windows Update segment, you need to simply type “update” in the search box. This process runs on all Windows versions. Then go to Windows Update, check for updates and install the updates if something is available.

Solution 2 — Scan your PC

Perform a full system scan to identify and eliminate any virus or malware that possibly entered into your PC. Malware may create different problems on your computer, which includes the Kernel Security Check Failure error. Conduct a full system scan so as to detect any malware which been run on your computer. You can easily access the Windows’ built-in antivirus, Windows Defender, or any other third-party antivirus solutions.

Here is the process of running a full system scan on Windows 10 Creators Update:

Step 1. Go to Start and then type ‘defender’.

Step 2. Double click Windows Defender to open the tool.

Step 3. In the left-hand pane, choose the shield icon Kernel Security Check Failure fix.

Step 4. In the following window, click the Advanced scan option Kernel Security Check Failure fix.

Check the full scan option to start a full system malware scan.

Note: If the antivirus cannot eliminate the malware it identified, first you should try installing a different antivirus to see if it works. If it does not, then you will most likely have to restore your operating system to a point where you did not have this issue or completely reinstall the operating system.

Solution 3 — Check your disk for errors

On Windows 10, you can run a disk check using Command Prompt.

Start Command Prompt as administrator and type the chkdsk C: /f command followed by the Enter key. Replace C with the letter of your hard drive partition.

As a quick reminder, if you do not use the /f parameter, chkdsk displays a message that the file needs to be fixed, but it does not fix any errors. The chkdsk D: /f command detects and repairs logical issues affecting your drive. To repair physical issues, run the /r parameter as well.

Note: This method can take up a lot of time. It mainly depends on the hard drive’s memory as it can go between half an hour and two hours before it is completed.

Solution 4 — Kernel Security Check Failure after overclocking

If you have overclocked your PC, then this can justify why you’re encountering Kernel Security Check Failure errors. Return your PC to its previous arrangement and uninstall any overclocking software which is been run on it. Then reboot your machine to check whether the error still exists.

Solution 5 — Run System Restore

If the issue has started lately, run a System Restore. If your problem happened after you installed new software on your computer, this tool will definitely help you to eliminate newly added apps and programs.

The System Restore option enables you to return to all the previously well-performing system arrangement without even losing a single file. Just some of the customizable features and settings are lost.

Windows 10 gives a range of advanced recovery options that lets you clean install the OS. You can also utilize the ‘Reset this PC’ recovery option.

Step 1. Go to Settings and navigate to Update & Security

Step 2. Click on Recovery in the left pane.

Step 3. Click on Get Started with Reset this PC > choose to Keep your files.

Step 4. Follow the on-screen instructions to complete the reset.

The steps above made you understand how to resolve the “Kernel Security Check failure” error message on your Windows 8.1 or Windows 10 PC. However, if there is a hardware failure of the HDD or the RAM memory in your device, you will probably have to substitute it with a new one.
