[comp.sys.mac] sys bus errors/excel:help?!

     i've had a problem recently with  bus  errors:
system  error  1,  and  i'm wondering  if  this is a
hardware or software problem. it occurs
frequently just with excel 1.4, sometimes when
i'm opening another document, sometimes when
i'm closing  a  window  that  has been saved, and
sometimes when i'm just resizing a window. it
doesn' seem to occur just during disk i/o.
     this can happen when i'm running a macro to do
these activities, and  other times when i'm doing
them manually. there doesn't seem to be much
predictability as to when this will occur: it may
occur after numerous complex operations,  and at
other times after only several simple operations.
     i'm  using  a 2 meg mac ii with a cms 60meg
internal drive. i have it occur with both syst 6.0.2
system software, with macromaker turned off,
and only apple das  and  cdevs  installed. it also
happens with system 4.2/finder 6.0 with only
apple das and cdevs. this occurs even without
using  multifinder.  i  also  get system   error  7:
privlege  violation  error,  at  times  following the
 same operations, and often after the system
crashes following a system error 1 when i re-boot.
 i  often  loose the monitor after one of these
crashes: sometimes it's totally black, and other
times a get a nonsense of noise lines like  a  tv
with it's horiz and verticle hold messed up.
     is  the  problem  software and what i'm doing
with it, or hardware?i had my logic board
replaced the other month when i lost all power
from the cpu  to  the keyboard and the monitor
(and they say it wasn't the power supply.) ie., this
is a relativly new logic board. i did install new
drivers a few  weeks  ago  on  my hard  disk,  but
i wasn't running excel before to notice a problem.
these things haven't occured with any other
applications, yet!  any  ideas?  any  way  i  can
trouble shoot this? anything i should be doing with
excel to avoid this?
