Are you sure the memory is good?  Usually this is caused by the first 
stick going bad, and the machine can't continue onto any additional 
sticks.  It wouldn't surprise me if, when the RAM got unseated, the 
memory got zapped.

This memory shouldn't be too hard to find.  Certainly easier to find 
than a motherboard.
