How To Fix Kernel Security Check failure Error
To fix the kernel security check failure error follow these steps
1 : Update Device Drivers
The first thing we are going to do to is upgrade the device drivers. The driver has most likely become corrupt or has a bug which is causes the crashes. To update your device drivers follow these steps.
Open up device manager (Click start, type in “Device Manager” and hit enter) Now expand the driver that is causing the issues (Below I am using the network adaptor as the example.)
Right click on the device and select properties, then click on the driver tab and note down the driver date and version. (We can see below the version is 126.96.36.199)
Now search on the internet for an updated driver. We are looking for a driver newer than 26/03/2016 or 188.8.131.52. Download that driver and save it to your machine.
Now head back to device manager and right click on the device and select update driver, Follow the prompts to update.
Restart your machine after the driver has been updated. Monitor if your machine still has the issue. If your machine still has the System Service Exception error try the next fix.
I recommend you start by updating the following three drivers, if you are still experiencing crashes after you can try to upgrade other drivers in your system.
2 : Re-Install Device Driver
The issue could be caused by a corrupt device driver. We are going to uninstall and reinstall the driver which should resolve this issue.
Open up device manager (Click start, type in “Device Manager” and hit enter) Now expand the driver that is causing the issues, right click on the device and select “Uninstall Device”
When the driver has been uninstalled reboot your machine. This will completely remove the driver from your system.
The driver should auto install when windows 10 has restarted. Go back in to device manager and right click on the device and select update driver, Follow the prompts to update.
3 : Fix File Corruption On Your Machine
It is possible that either a device driver or a windows 10 operating system file has become corrupt and is causing the Kernel Security Check failure crashes when that file writes data to system memory.
To check your hard drive for errors do the following
Click Start, type “CMD” then right click on CMD and select run as administrator
In the black windows that pops up type in “CHKDSK /f /r”
The scan with either run or you will be prompted to type y then restart your machine
When the scan is finished restart your machine
Again monitor your system and continue to the next fix if needed.

Virus’s are also known to cause the Page Fault In Nonpaged Area Blue Screen error in Windows 10. Make sure your anti virus is up to date and perform a full scan of your system.
If you don’t have any anti-virus installed download and install AVG Anti Virus, they have a free virus scanner which is really good (I use it all the time)
You can also perform an online virus scan by visiting this link, The website will scan your local machine and will remove any viruses you might have.

Once the download has completed it will start to install on your system.
When the install has finished the status should change to Pending Restart, at this time click restart now

It is possible that one of your memory modules is not in the slot correctly. Taking the memory module out then place back in will resolve this. To reseat your memory module do the following

Remove the power cable from your computer
If you are using a laptop remove the battery
Locate where your memory modules are (You might need to look in your computers manual)
Remove one memory module at a time and replace the memory module back in the same slot
Connect battery + power
Turn your machine back on

Left click on the start menu
Type in Windows Memory Diagnostic
Launch the program
Click on Restart now and check for problems
Your computer will now restart and automatically start a scan on your machine
If the tool runs and does not find any issues then skip to the next step
If the scan does find an issue it is recommended to replace the memory in your machine
9 : Disconnect External Hardware
Do you have any external devices connected to your machine?
It is possible that one of these devices has become faulty and is causing the crashes. I recommend to disconnect all devices and monitor your system for crashes.
If your machine stops crashing you know it is an external device. External devices can include
USB Mouse + Keyboard
Externally connected storage
10 : Kernel Security Check Failure After RAM Upgrade
If you have just upgraded your RAM and the Kernel Security Check Failure blue screens started there are a few things we can do to try to resolve this.
First remove the extra RAM that you installed
Now download and install a BIOS upgrade for your system
Re-install the RAM upgrade
If the crashes are still happening are all the RAM modules the same in your machine? If you have different types of RAM in your machine this can cause issues.
Remove all RAM modules from your machine and only install the new RAM module. If the crashes still happen it is possible that the new RAM is faulty.
