To fix this error, we  recommend the following 3 solutions:

Restart your system after the scan is completed. If that does not help, you may need to run SFC at boot time.

3] Using DISM

You may repair potentially corrupted system image using DISM Tool. If a Windows image becomes unserviceable, you can use the Deployment Imaging and Servicing Management (DISM) tool to update the files and correct the problem.

To run the DISM Tool, hit the WINKEY + X combination and click on Command Prompt (Admin).

Now enter the following three commands sequentially and one by one:

Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth

Let these DISM commands run and wait until they execute.

4] Try BSOD troubleshooter

What failed win32full sys?

The possible reason is driver failure because of incompatibility between Windows and the driver’s version. You will need to boot into the safe mode and use an older restore point to fix the problem. In case you cannot, then you will need to reset the PC.

What does Driver_irql_not_less_or_equal mean?

The error code—DRIVER_IRQL_NOT_LESS_OR_EQUAL is shown when the network driver uses an incorrect memory address. It is possible that you may see mention of ndis. sys on the boot screen. PAGE_FAULT_IN_NONPAGED_AREA is a similar error code that occurs because of the same problem.

What is a Non-paged area?

There is a section of memory known as “the Non-Paged area” in which important data is stored.  Not only is it needed all the time, but it belongs solely to the OS. If any process tries to access a restricted area, OS throws an exception leading to BSOD.
