Hi Steve,
This can be a kernel mode crash issue. Generally it occurs when a driver tried to access an address that is pageable (or that is completely invalid) while the IRQL was too high.
To troubleshoot this kind of kernel crash issue, we need to debug the crashed system dump. Unfortunately, debugging is beyond what we can do in the forum. A suggestion would be to contact Microsoft Customer Service and Support (CSS) via telephone so that a dedicated Support Professional can assist with your request. Please be advised that contacting phone support will be a charged call.
To obtain the phone numbers for specific technology request please take a look at the web site listed below:

I hope the problem will be resolved soon. Thank you for your time and cooperation!
