This is a totally different application (no vidio or animation).

I’m a mechanical CAD engineer running an nVidia Quadro 5000M on an HP EliteBook 8740w Notebook computer. For several weeks I have had a problem with my system crashing. The computer totally shuts down–it completely powers-down instantaneously with no warning. I doesn’t only happen while running a CAD application. Sometimes I’m using a single Microsoft Office application when it happens, sometimes I’m just online with Internet Explorer.

At first I tried reducing the resolution on my monitors, but that didn’t seem to help. Then, like another writer above, almost by accident, I narrowed the problem down by observing that it only occured whenever I was driving two monitors (which, until this problem surfaced, I usually did). If I only drive one monitor, there’s no problem. It doesn’t even have to be the notebook’s own mobile monitor–I can drive another, larger, higher-resolution monitor, but just not two monitors at once.
