So on August 8th, after I sent NVidia Hardware IDs, he sent me back the following:
Thank you for the update and I appreciate your efforts in troubleshooting the issue.
As per the provided info, I see that the notebook supports the Hybrid technology and unfortunately our driver is not compatible with the Hybrid notebook. I request you to kindly contact the laptop manufacturer to get the supporting display driver. If issue persists, then you would need to get the laptop tested and replaced based upon the warranty.
Please get in touch with us, if you need further assistance and I would be happy to help you.

So he's saying it is a hybrid (at that time I didn't know what that meant). But here's the thing.. it used to be just fine!
In the Control Panel, I see NVidia Graphics Driver 331.65 and NVidia Update 1.15.2. I am not sure why the Update is there; I chose not to install it while installing the driver on the 29th.
Uninstall Nvidia driver - and without restarting I will...
Uninstall both programs from Control Panel
Install the Optimus and cross my fingers!
