Amazingly, when I DDUed the M2400 again and used the Dell drivers from 2009 it doesn't BSoD at all. WTF. Nvidia, not even once indeed.Great, it appears the GPU on the M2400 is screwed up. Sigh. Nvidia, not even once. Let's see if they want to give me a partial refund so I can buy a new mobo off Parts-People.
