Explorer.exe crash loop - ntdll.dll file implicated

Hi there,
This question pertains to a Dell Inspiron 15 N5040 Laptop that I have attempted to upgrade to Windows 10. Unfortunately on both occasions after installing Windows 10 after logon the explorer.exe program begins a crash loop, rendering the laptop about as useful as a brick.
The error log is below, I cannot offer it as a .zip file as the computer is not active long enough to do that.

Hi I'm not qualified to advise BSOD, but that has already been solved here on the forum!!
You can find the link here! Hope I'm not breaking any rules!!
BSOD - Posting Instructions
explorer.exe crash loop caused by ntdll.dll

Unfortunately I have tried everything I can see listed as a solution in the BSOD related thread with no fix. I had already gone over that thread as part of my attempts to solve this issue.
Should I move this thread to the BSOD forum?

Hi! If your thread needs to be moved, a staff member will move it. This is what I find researching your error!
Maybe other members here have a better solution?? There is a lot going on in this link, but you might give it a look!
