Most of the time, this machine boots fine; but, on relatively rare occasions, it simply will not POST. If I temporarily disconnect the power or turn it off at the power supply switch, it will POST and boot just fine 100% of the time.

This problem has followed this board from its original installation into another case so it isn't the power supply, hard disk or CD drives as they have all been changed, too.

The board is a cheapie, an Amptron all-in-one with an Athlon XP processor.

Any suggestions?

It's an Antec. I paid about a hundred dollars for it.

This Antec has run several boards without incident and this board has had this problem on a cheapie power supply and now on this Antec.

It would seem you have ruled out the ps. Have you pulled the board and checked for bad caps? If I had to guess, I would say you have a bad VR on the board. It is not supplying the correct current to the cpu; again it is just a guess.
