The video drivers are the latest from the Dell Support site, which I have been running for well over a year with several high-end graphics applications. I have never had an application corrupt the display, let alone shutdown the laptop! Very bizarre...

I have to believe that there are other customers with nVidia Quadro-based systems...
Also, I have the latest BIOS and Video BIOS...and have also tried various resolutions and color depths...
