200W max on the 3.3/5V combined rails. 5V max is 30 amps.
The 12V rail is 15A max.
Your board doesn't have a separate 2x2 12V input, so the
power for the AthlonXP could be coming from +5V.

There are several 2000+ processors. This is the oldest one.
1667 (2000+) OPGA 133 256 12.5x 1.75V 90oC 62.5W
(62.5W / 5V) * (1/0.90) = 13.89A from 5V rail (assumes 90% Vcore efficiency)
Two opticals, take 5V @ 1.5A or so each.
The +5V isn't too much for the supply.
The 3.3V might draw another 10A or so, just a guess, for the motherboard.
Total combined 3.3V/5V is 117W or so.
The video card is about 35W, but again just a guess.
While the estimates don't seem to indicate the power supply
is undersized, perhaps the supply is just getting "tired".
You have to observed the voltage value on the rails (with a
multimeter), to see whether there are any signs the supply
is not happy. If the BIOS has a hardware monitor page, that
can be used to display the voltages as well. But by the time
you get into the BIOS, the spinup interval of the disk could
be completed.
Another test you could run, would be to unplug some hardware
and see if the symptoms change. If the Maxtor is disconnected
(both data and power), are the symptoms the same (the whining
sound) ? You may have to change jumpers a bit, to do the test.
