As I said previously, I could get the computer to boot with the DDR sometimes. Well, one of the times that it booted, it did not recognize the modem (add new hardware wizard popped up). So I decided to remove it and see what happened. I also wonder if it is something with the IRQ's, but I wouldn't have thought switching the memory would affect that. Shows how much I know.
I just thought I'd explain how I figured this out.
