manual here

says Phoenix - Award bios...which is not real helpful

Even though your RAM did not fail the test...
I'd try some different RAM
or run it on one stick at a time if possible

The BIOS ID is right in your post above: BIOS ID: Phoenix-Award.  It's
an Award BIOS.
Award BIOS beep codes here,
http://bioscentral.com/beepcodes/awardbeep.htm ,

indicate a CPU overheating problem.  Your description of the system
running slow, etc. could be due to the CPU being throttled back to a
slower speed when it gets too hot.  If I recall, P4s were known for
getting very hot.

I would remove the heatsink, clean it and the CPU really well and
reinstall the heatsink with a THIN layer of heatsink compound.  Also,
make sure the rest of the inside is cleaned out.

If that is not the problem, or you are absolutely certain the CPU is not
overheating, I would suspect the power supply is going bad.  Check all
the power connections and make sure there are no signs of burned, or
melted pins.  Check the voltages at the ATX connector with a DVM and
make sure they're all within tolerance (+-5% of the proper voltage).
Don't forget the extra +12V connector for the CPU if your MB uses one.

I think I'm getting the "repeating high/low they mentioned. My P4 can
take up to 67c, it usually runs at about 30c.

I put a huge heat sink on this thing:
http://www.neoseeker.com/Articles/Hardware/Reviews/ttgoldenorbII /
I'd have to take the board out of the case to get it off the processor.

I found a couple apps that measure the temperature of the video card and
mine was running REALLY HOT! I took the heat sink off that and re-
applied thermal paste. Dropped the temp on the card 10-15 degrees. I
wonder if it was baking the cpu with all the heat comming off it.
Added a pci slot fan to pull more heat out of the case and away from the
card and CPU. Will have a friend test the power supply with a meter this
weekend.
Thanks everybody.

Not the Golder Orb!!  I remember that heatsink/fan and it wasn't known
for being very efficient at all, although I didn't know they made one
that large!

It's possible the extra heat from the video card was making the CPU temp
artificially high.  It's good that you've got the temp down.  Good case
air flow is also very important.

Also, make sure the fan on the CPU heatsink is spinning as fast as the
MB expects.  If the fan slows down while the system's running, it can
lead to high CPU temps and/or you may be getting an alert that the fan
is too slow.  Check in the BIOS for settings for CPU fan speed and alert
threshold settings.

Somewhere on teh intarwebs "RobV" typed:

Make up your mind. You either remeber "it" or you don't.

There were many 'Orbs" made by Thermaltake, quite a few of them golden. The
original Golden Orb was pretty much the forerunner of affordable
after-market CPU heatsinks and was considerably more efficient than Intel
HSFs of the time. Tt lost the plot with the orb range a bit when other
manufacturers came along and gave competition, producing some very niosy and
some not-so-great models. However, the original was a great cooler. The
Golden Orb II is, like the original Golden Orb, a reasonably-priced
after-market HSF that is better at cooling a CPU than the standard (at the
time) Intel HSF.

Sure, it ain't up to the standards of some of today's coolers but it's an
improvement over stock on an old Prescott.

The Tt golden Orb fan runs at 1.5K rpm standard so you could be onto
something there. If there is a BIOS routine enabled that adjusts CPU fan
speed that could be a possible cause of the beeping. You shouldn't use a
'variable' setting with a cooler like the Tt GO II, it's quiet enough at
it's default speed.

Another thing to consider is northbridge temp, although one would think with
that Tt throwing air 360° it should be keeping the NB cool.
