Solution 1: Look for memory issues on your computer.
Blue screen with stop code kernel security check failure may result from memory issues, as I showed before. So, how can you tell if you have a memory problem? As a result, the entire process is simplified thanks to the built-in Windows memory diagnostics tool.
I’ll demonstrate how to use Windows 10’s memory diagnostics tool in this article.
Step 1. Activate the memory diagnostics programme.
- Cortana may be asked questions by typing memory or mdsched into the search bar on Windows 10.
- To use the tool, go to Start > All Programs > Accessories > Memory Diagnostics.
Step 2: Inspect the tool for flaws.
- To see whether your computer has a memory issue right now, choose one of the two choices below.
- Check any issues by restarting your computer right now.
- Next time I start my PC, I’ll double-check for errors.
- Run a RAM diagnostics check on your machine regardless of your selection.
- If the kernel security check fails because of memory issues, try replacing the present memory card with a new one.
Solution 2: Fixing Hard Drive Errors
Hard drive errors such as KERNEL SECURITY CHECK FAILURE may be the source of the error code. To fix hard disc errors, you may use either Windows’ built-in CHKDSK programme or a third-party hard drive repair tool. I’ll demonstrate both for you right now.
Use CHDSK to Repair Faulty Hard Drives
Step 1: Start the Command Prompt on Windows 10 by typing cmd.exe.
- Type cmd into the Cortana search box in Windows 10 and press Enter.
- You may also pick Run as administrator by right-clicking and selecting “Run as administrator.”
Step 2: Use Command Prompt to look for and repair hard drive problems.
When asked for the drive letter of the partition you want to scan, type *: /f and press Enter.
Close Command Prompt by typing exit and pressing Enter to confirm your action.
Here are two characteristics that are often used to diagnose and correct hard disc problems.
- /f – scans the disc and instantly fixes any hard drive problems.
- Search for faulty sectors on the disc and attempt to salvage any usable data that may be contained there.
The Windows 10 CHKDSK tool is a lifesaver. Users who aren’t acquainted with instructions, on the other hand, are more likely to make mistakes. As an alternative to CHKDSK, I’ll show you MiniTool Partition Wizard Free Edition, which is completely free.
