May be hardware related - I'd suspect power supply, overheating or RAM
if it's hardware.
Also, depending on the unit, there were lots of motherboards made with
bad capacitors - take a look at them for bulged tops.

Can you pull it out of service long enough to run a memtest on it? and
watch the temps while you do so?
