Fix Windows 10 kernel security check failure blue screen error
The Kernel Security Check Failure error is a critical issue that can disrupt your Windows operating system. This error is a result of a failure in the kernel, which is the core component of the operating system responsible for managing system resources. In this article, we will delve into what causes this error and provide step-by-step solutions to resolve it.
What is Kernel Security Check Failure?
The Kernel Security Check Failure error is a blue screen error (commonly known as the “Blue Screen of Death” or BSOD) that occurs when the kernel detects a violation in the system’s security. Essentially, this error indicates that the core components of your operating system have encountered a problem that cannot be safely resolved without a system restart.
Common Causes of Kernel Security Check Failure:
Faulty Hardware or Drivers:
- Hardware components, such as RAM or hard drives, may be malfunctioning.
- Outdated or incompatible drivers can also trigger this error.
Corrupted System Files:
- Over time, system files can become corrupted due to various reasons, leading to instability.
Memory Issues:
- Problems with RAM modules can result in memory-related errors like Kernel Security Check Failure.
Software Conflicts:
- Conflicting software or poorly designed third-party applications can disrupt the system’s stability.
Check for Hardware Issues
- Begin by inspecting hardware components for physical damage or loose connections.
- Replace any faulty hardware to ensure stable operation.
If everything appears intact, carefully reseat components like RAM modules, graphic cards, and cables to ensure they are securely connected
Disconnect any unnecessary peripherals (like printers or external drives) and remove any additional RAM modules or expansion cards. Boot the system with only essential components.
Monitor temperatures using software like Core Temp or HWMonitor. Overheating can lead to system instability.
Update Drivers
Open the Device Manager by right-clicking on the Start button and selecting “Device Manager.” Look for any devices with a yellow exclamation mark, as this indicates a driver issue.
Go to the official websites of the hardware manufacturers for components that may have outdated drivers. Identify your specific model and download the latest drivers compatible with your Windows version.
- Run the downloaded driver installation package. This typically involves double-clicking the downloaded file.
- Follow the on-screen instructions provided by the driver installation wizard.
- Restart your computer if prompted to complete the driver installation
Run Windows Memory Diagnostic
Click on the Start menu and type “Windows Memory Diagnostic” in the search bar. Select the tool from the search results.
- Choose the option to restart your computer and check for memory problems.
- The tool will initiate a comprehensive memory test to identify any potential issues with your RAM modules.
- After the test is completed, your computer will restart. Once back in Windows, you can view the results of the memory test.
Scan for System File Errors
Click on the Start menu, type “cmd,” right-click on “Command Prompt,” and select “Run as administrator.” In the Command Prompt window, type the command “sfc /scannow” and press Enter.
This command will initiate a scan for and repair of any corrupted system files. Once the scan completes, the Command Prompt will display the results. Follow any on-screen instructions provided.
Check for Software Conflicts
Start your computer in safe mode, In Safe Mode, your computer will load with a minimal set of drivers and services, which can help isolate potential software conflicts.
Use your computer in Safe Mode and observe if the Kernel Security Check Failure error persists.
If the error does not occur in Safe Mode, it suggests that a third-party application or driver may be causing the issue.
Check for Overheating
Use temperature monitoring software to check the temperature of your CPU and GPU. High temperatures can lead to system instability. Over time, dust and debris can accumulate in fans and heatsinks, reducing their efficiency. Clean these components to improve cooling.
If you have overclocked your CPU or GPU, revert them to their default clock speeds. Overclocking can lead to instability and system errors.
Update Windows and Drivers
Ensure that your Windows operating system is up to date with the latest security patches and bug fixes. These updates often include important stability improvements.
Graphics card drivers are critical for system stability, especially during graphic-intensive tasks. Visit the GPU manufacturer’s website to download the latest drivers. Here is different ways to update device drivers on Windows 10/11
Use a reputable antivirus or anti-malware program to perform a thorough scan of your system. If any malicious software is detected, follow the recommended actions to quarantine or remove it.
