How do I fix kernel security check failure?.
In a world where computer access is more important than ever, a Blue Screen of Death (BSOD) error on a Windows PC can stop this access completely. Unfortunately, common BSOD errors like an unexpected kernel mode trap or stopping a critical process prevent your computer from running until you fix the underlying problem.
Another common BSOD error that may appear depending on the circumstances is the “kernel security check error” BSOD. This issue usually occurs due to corrupted system files, but it can also be due to faulty hardware or outdated drivers. Here’s what you need to do if you want to fix the BSOD error while checking kernel security.
What Causes a Kernel Security Check Failure BSOD Error on Windows 10?
Some BSOD errors are difficult to investigate, but with a BSOD error, kernel security checks can usually be assumed to indicate one of two things: a hardware problem or corrupted (or outdated) system files.
These problems can cause your computer to somehow try to access the Windows kernel incorrectly. As the most secure of all system services, illegal access to the system core causes Integrity check to fail, crash your PC and display such BSOD error.
If your system files are damaged or out of date, you can usually fix the problem by running Windows Update. This will install all available system updates, including device driver updates. You may also need to run other maintenance tools such as the System File Checker (SFC) and chkdsk using Windows PowerShell.
Hardware issues such as faulty system memory can also be causing the problem. You may need to test the hardware, and if you find it malfunctioning, consider replacing it. If that doesn’t work, your only recourse may be more drastic measures (such as resetting Windows).
Check for System and Driver Updates
In many cases, the Windows Stop Code message “Kernel Security Check Failed” is caused by an outdated system with missing (and required) bug fixes. To fix this problem, you need to check Windows Update for new system and driver updates.
While updated drivers should fix the problem, you may find that new drivers are also causing the kernel security check to fail in Windows 10. You may need to roll back the driver if you see this error after you recently updated your device drivers, either manually or via Windows Update.
Run the System File Checker and Chkdsk Tools
If Windows system files are compromised or damaged, Windows will stop working as expected. You can help resolve the issue by checking the integrity of your system files and the file system of your hard drive using the System File Checker (SFC) and chkdsk tools.
While the SFC and chkdsk tools are not guaranteed fixes, running them (at the very least) will allow you to determine if your system files are faulty or not.
Test Your System Memory
If the SFC and chkdsk tools do not offer a solution to the kernel security check failure issue in Windows 10, you may need to take a closer look at your hardware status. For example, memory problems can directly trigger a kernel exception message like this.
The Memory Diagnostic Tool will stress test your system memory to make sure it is working properly. If any problems are found, you will need to consider replacing your system memory in order to resolve them.
Reset Windows 10
Unfortunately, sometimes only decisive action can resolve common BSOD issues such as Kernel Security Check Failed BSODs. If you are unable to fix your computer, you should consider doing a factory reset or cleaning Windows 10.
This comes with the risk of losing your personal files in the process, so be sure to back up any important files before starting.
These steps will only work if Windows can still boot. If that fails, you need to create Windows 10 installation media using a USB drive or DVD and instead follow the on-screen installation instructions to reset Windows 10.
Fixing a Kernel Security Check Failure BSOD Error
The above steps should help you fix BSOD error while checking kernel security as well as avoid them in the future. You should check your computer’s performance regularly to monitor for any further issues, update your system to make sure you have the latest bugs and security fixes, and check regularly for malware.
However, the quality of a PC depends on the hardware it runs on. If you see BSOD errors appearing at an alarming rate, it could indicate hardware problems that you cannot resolve. It might be time to upgrade your computer with new hardware, or consider building or buying a new PC.
First, right-click the Start menu and select Settings.
- From the Settings menu, select Update & Security> Windows Update and select Check for Updates to search for new updates. If any updates are available, select Download (or Download and Install) to begin the installation process. After installing all available updates, restart your computer to complete the process.
- To do this, open a new Windows PowerShell window by right-clicking the Start menu and choosing the Windows PowerShell (Admin) option.
- In a PowerShell window, enter sfc / scannow to start the System File Checker tool. You will need to wait for SFC to finish scanning your system files and, if possible, restore them.
- When you are finished with the SFC tool, enter chkdsk C: / f to check the integrity of your system drive’s file system. Windows will ask you to schedule this for the next reboot. Which will complete the boot level scan of your drive. Type Y and press Enter to confirm this,
then restart your computer.
- To test the health of your system memory, you will need to test it. This can be done using the built-in Windows Memory Diagnostic Tool. First, right-click the Start menu and select Run.
- In Run, enter mdsched.exe and click OK.
- In the Windows Memory Diagnostic window, Windows will ask for permission to restart. Select “Restart now” and check for problems to do so immediately. Or select “Check for problems the next time you start your computer” to postpone it until the next restart.
- If Windows 10 can still boot. you can reset it by following these steps. Clicking the Start menu and choosing Settings.
- From Settings, select Update & Security> Recovery> Start to begin the reset process.
- The Reset This PC menu will prompt you to save files or completely erase the data from the disk to restore Windows 10 to factory defaults. Select “Keep my files” or “Delete All” to make your choice.
