When troubleshooting an error, it is critical to have a clear understanding of the factors that caused it. Because of this, we have highlighted some of the most prevalent causes that might trigger a Kernel Security Check Failure error:

  • System files that have been corrupted – Even Microsoft makes mistakes from time to time, releasing flawed upgrades that cause the system to crash without the user’s knowledge or approval.
  • Hardware that is incompatible with or malfunctioning – A stop code can be generated by unseated hard drives, RAM chips, or unsecured connectors. Check that all hardware components are securely fastened, especially if your computer was recently opened. To be on the safe side, unplug and then reseat all of these components.
  • Drivers that are out of date or unsuitable – Oftentimes, old or incompatible program files or device drivers might cause intermittent BSOD STOP errors.
