We need a lot more details David.  You've been around here long enough
to know this isn't sufficient detail to allow us to diagnose or assist.
 You mentioned a specific disk subsystem problem, but then the specs on
the CPU as supportive evidence?

David to his mechanic:  My engine doesn't run right.  Here's a scratch
on the rear bumper, see, that might have something to do with it.

Sigh...
