I was using AMD durons in mine.
But seen as the board worked before, I will retract that reasoning.
I do see what could possibly the culprit - the Nvidia driver that you 
speak of, was it the 3D driver that is out of restricted? I have seen

Nvidia driver installed.
Try going back to the default video driver and see if your unit shuts down.
