Tech support is a painful and mostly unsung profession. We should all give a special thanks to HP tech support guy John Camparone, who apparently went to truly great lengths to diagnose and debug this last problem with NVidia. Thanks, man.

To resolve the problem, do the following:

Open the registry editor (regedit)

Navigate to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management 

Add a new REG_​DWORD entry called SessionImageSize with a value (decimal) of 20

Reboot

This process solved my problem, thought it would be nice to put this where other may find it quickly.
