I had a very similar problem.  I blamed RedHat, I blamed my SCSI card
and in the end, it was my power supply.

Changed the power supply and the machine has been up ever since.

The way I isolated it:

I left the machine in BIOS mode (IE: don't boot an OS) left it for as
long as it took, and it re-booted, and/or locked up.

The newer machines (CPU's and Hard disks) draw more power..
Older Power supplies may have dried up Filter caps..

YMMV, but check that.  It has happened to me on two machines over the
last three months.  Weird..

Rgds,
Darryl
