A BSOD kernel Security Check Failure Windows 10 is another common BSOD error that can appear under certain conditions. Corrupted system files are usually to blame, but faulty hardware or out-of-date drivers can also be blamed. Here’s how to fix a BSOD caused by a failed kernel security check.
What Causes a Kernel Security Check Failure Error in Windows 10?
Kernel Security Check Failure not restarting: Some BSOD errors are challenging to investigate, but if you get a kernel security check failure BSOD, you can assume one of two things is wrong, either your hardware is broken, or your system files are corrupted.
These issues may result in your PC making an incorrect attempt to access the Windows kernel. Illegal access to the system kernel, the most secure service in the operating system, causes an integrity check to fail, resulting in a crash and a BSOD error like this.
In most cases, running Windows Update will fix problems caused by corrupted or outdated system files. All available system updates will be installed, including any device driver upgrades. Windows PowerShell can also run other maintenance utilities like System File Checker (SFC) and chkdsk.
Faulty system memory or other components could be the source of the issue. You may want to check your hardware for problems and replace it if necessary. If that doesn’t work, your only option may be to take more drastic measures (such as resetting Windows).
Check for System and Driver Updates
An outdated system with missing (and necessary) bug fixes frequently results in a Windows stop code “kernel security check failure.” Update your system and drivers to the latest versions through Windows Update to fix the issue.
1. Start by right-tapping the Start button and select Settings from the context menu that appears.
