Looking to fix kernel security check failure in Windows 10, then here is a step by step guide.
I am sure you might have heard of the Blue screen of death, and one of the main causes for encountering BSOD error is Kernel security check failure in windows 10.
There can be several reasons why you have encountered this error on your windows operating system.
The following are some of the reasons for Kernal security check failure:
- Memory Problems
- After Windows Update
- Outdated Drivers
- Corrupted Windows Files
- Damaged or corrupted hard disk or SSD.
- After RAM Upgrade
- After Installing Windows
As you have seen there can be many reasons why your are getting blue screen error. We will look at each in this guide. Here is how blue screen of death typically looks like in Windows 10.
Windows have a great utility, which lets you check what causes an error or failure to the system, and that utility is Event viewer.
Using the event viewer, you can check the cause of the Kernel security check failure error or Blue screen BSOD error.
Follow the steps:
Windows + X Key and click Event Viewer.
2. Now the event view will open containing a lot of logged information about the computer hardware and software, i.e., warnings and errors
3. Click Action on the menu pane and select
Create Custom View.
4. From the logged drop-down, select any time range depending on what time you got blue screen error.
5. For the Event level, checkmark error, critical and warning.
6. Now click on event logs radio button and from drop-down, select Windows Logs.
6. Click OK.
7. Now, provide any name to the custom event view and press OK.
Now the Event Viewer automatically loads the new filtered view.
At last check for the event around the time of blue screen error. For more information about the event, double click on it.
Alternatively, there is another handy program for finding the reason for the blue screen error called BlueScreenView.
When you open BlueScreenView, it displays a list of saved dumped files.
You can easily click on any dump file to get more information and get specific information like Bug check String and Bug check code, which are quite useful for finding the cause of BSOD errors.
BluescreenView is the easiest method for finding the reason for BSOD errors. I highly recommend it.

If disconnecting fixes the error, then there must be compatibility issues, or something else is wrong with the hardware.
In that case, you can either upgrade drivers for the device or try contacting the hardware manufacturer for support.
Sometimes viruses or malware can also cause kernel failure issues in Windows. And if you are into safe boot mode or don't have any third-party antivirus installed.
