My experience (which is admittedly limited) is that removing socketed 
chips, cleaning with contact cleaner, and re-seating the chips can make 
a pretty big difference.  This includes the CLCC-style socketed chips.

I'd also make sure none of the backplane pins have gotten bent while 
swapping boards, just for good measure.
