Pure hardware question

Energized UPS. Turned on PC. Dual channel notification noted in use by
bios. No hard drives, or DVD burner noted. Cannot find anything to boot
from. Reset PC reboot switch, same as above.
Deenergized UPS, immediately energized UPS. Same as above.
Deenergized UPS. Left off for just over a minute. Energized UPS, turned on
PC. Bios senses and notes hard drives and DVD burner.

Onboard ide not detected by bios: Primary master (80 GB WDC), primary slave
(200GB WDC), secondary master (LS120 version 5), secondary slave (TDK DVD
+4X burner). Detected in all cases: connected to Promise ide card - WDC
45GB, Fujitsu 17GB, connected to Adaptec 2930B scsi card, Seagate 4GB, IBM
9.1GB, Plextor 32TS cdrom.
All seems to be working okay now. Is something imminent to break?

By "de-energize" UPS, do you mean that the computer is being connected
directly to the main power? If this is the case, then the problem may
be located in one of 2 possible areas --- the UPS battery has gotten
bad and is no longer holding a full charge or the PSU is starting to
show signs of going bad. But there are many connections using the PSU.
Before proceeding any further with an analysis, just what is the rating
of the PSU in Watts and the rating of the UPS in Watts?

UPS has an on/off switch for the switched outlets which the PC runs off one
of these outlets. The PC will never run with this switch in the off
position. No power is present at such an outlet during that occasion.
Battery power has no influence in that situation.
Power supply is 450 watts.
Don't know the wattage rating of the UPS. Has worked for some years now on
both this PC and those I built prior to that with similar power
requirements.

If you have been using the UPS for years and not changed the battery then it
probably needs changing. I don't know if this would cause your problem. To
test if this is the cause take the UPS out of the equation and connect all
the equipment directly to the AC. It sounds more like a PSU or motherboard
problem. You have a lot installed in that pc. 450 watts may be marginal.
Many PSUs do not operate reliably when stressed to near their maximum
rating.

Found that if I turn on the UPS with the on/off switch, and wait about 30
seconds, there's no problems. Though, I didn't see that problem this
morning when I went throught turn on UPS, then PC routine without waiting.
Will see if things change with PC plugged directly into a wall outlet. The
UPS is an old PK blackout buster model. Company is out of business, think I
can still find a battery though.

Price out a new UPS. The price of a decent UPS has dropped considerably over
the past few years. It is often cheaper to buy a new one than a battery for
an old one.

Check your PSU's wattage load..

Any newer UPS unit will come with a warranty and/or a insurance policy, in
case the unit fails or burns out the PC.
