Bad_Pool_Caller BSOD after 32 - 64 bit upgrade

Hey Guys,
I've recently upgraded to 64-bit Windows 7 professional.
I've been getting a Bad_Pool_Caller Blue Screen frequently in the past few hours, I've reinstalled Windows, completely formatting the hard drive second time round to see if it will help which it didn't.

Here's the error report Windows gave me.

Any help will be appreciated.

I've tried to add the Mini-dump but its not letting me change the permissions in that folder
not sure if you guys will need it,
I'll add it if I figure a way around it.

minidump attached

I've narrowed it down to the vwififlt.sys file.
After some researched, I've updated my driver for Wi-Fi.
I'll give an update later if its solved the problem
