If it panic'ed you can see from the panic which process caused the panic (sometimes), but this doesn't tell you why. > PS - One more thing: Once, a message appeared on the console at crash > time about an invalid page fault while in kernel mode.

On this system I have had problems max'ing out the memory banks (although I used memory rated 60 ns.) and then getting similar panics. Good luck! Bernie
