Did you visually check the motherboard capacitors ?

  " As far as the behaviour of the computers go the symptoms
  leading up to the failure include the system failing to boot,
  locking up  or rebooting randomly.  This develops over a long
  period of time with increasing severity.  On the claims that
  we have looked at the erratic and illogical behaviour of the
  computer system generated extensive and unsuccessful repairs
  and ultimately the replacement of the computer.  With repairer
  explanations ranging from viral attacks, overheating, hard disk
  failures, incorrect over clocking the CPU with a strong
  preference for power surges as a cause, we believe that many
  capacitor failures have been undiagnosed or misdiagnosed ..."

this from:  Faulty capacitors give rise to motherboard failures.

Look at the metal tops of the larger, round capacitors on the
motherboard.  Are the tops buldging ?  Is there any carmel- brown
colored goo leaking (or tan colored salt extruding) from the tops
(or bottoms) of any of the larger-sized capacitors ?
