My MB is an ipiel-rn2 with a Core 2 Quad 9??? CPU, with 8GB of RAM (4 x 2GB).
As I said, it worked fine this morning before I took it apart, so I have no reason to suspect any of the components are bad. (Unless I broke something in the process of rebuilding it, which is possible.) I'm wondering if anyone has any insights into what the problem might be. My next step is to go back and try to get everything to work in the old case again, but I'm hoping to avoid that if it turns out to be a really east fix that I'm overlooking.
Thanks for any help,
