The computer is located in my apartment(recent construction) bedroom. Enough
said about quality
(or better yet lack of quality) of construction. It sits on a circuit which
has the associated computer components--speakers, scnner, printer, vcr,
monitor. Other than that the only other things plugged into that circuit are
a clock radio and lamp. That is a best guestimate. The circuits are
admittedly screwy and after first moving in I apparantly tripped a breaker
in my bathroom. Checked breaker box in laundry room with no results. When
the maintenance guy came by he took one look walked into the living room
moved a cabinet and reset a gcfi that fixed the bathroom problems--go
figure.

However, we recently moved and before moving the computer and all assorted
items were plugged into two circuits in a separate offic. In the past this
service provided adequate protection for several systems working
simutaneously. The problems began before the recent move and prior to
rebuilding the computer from scratch. They occurred once or twice after
moving into the new apartment and disappeared for about two months until the
most recent instataneous shut-down.

Regarding the psu and transients, could this be an antec associated problem?
The original power supply was purchased with the case. It was an Antec 400w
supply .Originally I had a soyo dragon installed and experienced no shutdown
issues. The shutdowns first occurred with the a7nx-e system which replaced
ther original dragon mohterboard. The A7nxe-based systems worked with no
problems for at least a year. The shutdowns began to occur somtime after
installing the conexant ups (months/weeks???) and then disappeared for two
or three months. They reappeared shortly before or after moving from the
house into the apartment and once again disappeared after the recent
rebuild and installation of A8n-e based system. At the time of the A8n-e
rebuild, I swapped out the orginal 400w power supply with an Antec Truepower
430w device. Finally after several months with no apparant shutdown issues,
they reappeared just this past week. The system has now been working for
two days after the incident and with no apparant problems.



Thanx for the continued follow-up. It is much appreciated.
