On the other hand, it could be the mobo.  Is that a Tyan S1571?  I had a
Tyan S1571 motherboard a while back which had the same (and worse)
problems.  Ran fine for a month or so, then all of a sudden I started
getting lockups, the hard disk wouldn't format, memory errors started
occurring at random addresses, etc. etc. etc.  It wasn't the hard disk, I
suspect the L2 cache memory on the mobo went bad. Tyan was no help, of
course; they take about a month to answer e-mail.

I finally replaced the mobo with an ABIT TX5, and with everything else the
same the computer now runs like a hose.
