Rich, 

  I have experienced the same type of problem.  My situation has to do with
an inconsistency in RAM speeds.  I found out that ONE of my RAM chips is
only a 120ns chip while the rest are 100ns.  By moving the chip around I
found I could change the area of the trouble occurrences.  Go figure.  I
replaced the 120ns chip with a 80ns chip.  Now the truoble is random 'main
board parity errors.' Go figure.  It seems all related to memory so I'm
upgrading my system memory to 2.5Mb. with 2 rows of 1Mb. chips and 2 rows of
256Kb. chips.  It may even be all related to when I installed new system
BIOS after installing a new 40Mb. EDI hard-disk.  It just seems to never
end...
