Thanks for the suggestion. I reset the cmos and tried with several configurations of the old and new ram. Eventually I took the MoBo out and seated the ram in with a little more force. This worked (the board appears to be a little warped) but then more fun begins. The bios recognizes all of the memory and memtest passes (I ran it all night and no errors). Windows however gives me a BSoD part way though startup. Sometimes but not every time it says IRQL LESS THAN OR EQUAL. I would just assume this is a memory problem but for the memtest results. Any help would be great.
