Fix: Windows 11 BSOD fails due to kernel security check

Some users have reported seeing Kernel Security Check Failed error messages in BSOD screens and have requested help resolving their issues. To maintain the aesthetics of Windows 11, Microsoft has replaced the blue background in BSOD (Blue Screen of Death) errors with a black background to better match the theme. As expected, this doesn't appear to have any significant impact on performance or the frequency of issues occurring, and for the vast majority of users this appears to be essentially unchanged. We’ve compiled a list of methods you can use to resolve kernel security check failure issues you’re experiencing, but first, let’s look at the main reasons. What causes kernel security checks to fail? When troubleshooting an error, it's crucial to have a clear understanding of what's causing it. Therefore, we’ve highlighted some of the most common reasons that can trigger kernel security check failed errors: ➡ Corrupted system files – Even Microsoft makes mistakes from time to time, releasing flawed upgrades that cause the system to operate without the user’s knowledge or consent crash. ➡ Incompatible or faulty hardware – An uninstalled hard drive, RAM chip, or unsafe connector may generate a stop code. Check that all hardware components are securely fastened, especially if your computer has been turned on recently. To be safe, unplug all these components and reinstall them. ➡ Outdated or inappropriate drivers – Often, old or incompatible program files or device drivers can cause intermittent BSOD STOP errors. ➡ Using an older version of Windows – It is generally recommended that you keep your operating system version up to date as new updates may fix bugs that you didn’t even know existed in the first place. ➡ Insufficient RAM – Usually an 8 GB RAM chip is more than enough for your computer, but in some exceptional cases, you may need to upgrade it. The most common of these are related to incompatible drivers, especially if you have switched to Windows 11 from a previous version of the operating system. If you are having problems, it may be because you are using a driver that worked fine in previous versions but not in the current version. When a Blue Screen of Death appears on the screen, the cause of death is often stated in the stop code. These key pieces of information point to the root of the problem. More power to you if you can replicate these error messages and research the root cause and solution.
