Do you have any spare DEM-16 cards in a known-good condition? I would want to make sure the cards were the issue before I move on to the DEI itself.
EDIT: Swap w/known-good DEI, as you probably already are doing. It's rare enough to me that the DEI just hates having any cards in it but I've known it to happen.
