Possible, but I think unlikely.  Isn't a celeron a pentium III or IV
without the on board cache?  i.e. much more recent than the original
pentium.

Easy enough to try.  I would rate it a long shot though.

Is there anything in /var/log/messages after a lockup?  If it is really
a hardware fault causing this, it will be sudden like lightning, no
logging.  Off we go, into the wild blue yonder... :-)

My first thoughts would be overheating or a power supply going bad.

Also power down the system completely (unplugged) and remove and
reinsert all the boards, connectors, memory.

Maybe someone else will have better insight.
