Usual cause: An attempt was made to touch pageable memory at a process internal request level (IRQL) that was too high.

Hey Dave for informational purposes I will tell you I have seen Antivirus mess with cng.sys That may not be the case here but just thought I would share the knowledge.

As dsprague rightly pointed out:

Please remove your Anti-virus Avast as this could be causing problems:

http://www.avast.com/uninstall-utility

Please install:

Microsoft Security Essentials.
Recommended from a strict BSOD perspective, compatibility & stability
compared to other antiviruses/internet security software. And it has a smaller footprint.

Microsoft Security Essentials - Microsoft Windows

Cheers
