I was able to find the following references to driver errors in one of the new crash dumps:
The first is the nvidea driver but you already have the latest version dated 25 Aug 2016. You could try uninstalling completely all nVidea graphics driver related files using the DDU method and then reinstalling with a clean install just the driver and PhysX files as you have done before.

The second is the Intel Network adaptor driver which is rather older and dated 18 Jun 2015. It would be worth looking for a newer driver for your network adapter.
As two of your BSODs were KERNEL_SECURITY_CHECK_FAILURE (139) errors it would be worth making sure you are up to date with your security and anti-virus software and running a full system scan, I don't think you have a problem here but as this error can sometimes be associated with malicious attacks it is worth checking.
