Why are you fixing things when you have no reason to believe a
defect exists there? Worse, is loading (flashing) a new BIOS when
hardware is unstable? An easy way to permanently destroy the
motherboard.
You are fixing things rather than first learning what is wrong. For
example, if a power supply spins it fans, then power exists. But is
power sufficient? Unknown. Fans can spin and power supply is still
defective.
Then you are trying to fix the power supply as if that was the
entire power supply system. It is not. IOW stop trying to fix
things. That comes later. First learn what is defective.
Central to your symptoms is the power supply controller. That means
you learn every input and output going to that function. And that
means those numbers posted here result in definitive replies from
those with better knowledge. Currently every post is wild speculation
- 'it could be this or could be that or... ' wasted time.
What is the power supply system doing? A two minute procedure
defines that in numbers in "When your computer dies without
warning....." starting 6 Feb 2007 in the newsgroup alt.windows-xp

Connector chart for where each color wire should be located:

In your case, most important are numbers as and in seconds after the
power switch is pressed on any one of green, gray, red, orange, and
yellow wires.
Also not described in that procedure but relevant to your problem
are voltages between pins that the power switch connects to; both
before and when power switch is pressed. Any answer that says it is
OK is wasted time. Critically important are numeric values. Your
replies will only be as useful as information you post.
Even swapping power supply accomplished nothing. For example, after
replacing power supply, list the components you know are good or bad.
Why is that list still empty? Because after all that work, nothing
was accomplished. But then that is also a problem created by those
who say, "it might be this or might be that or might be ... ". Wild
speculation accomplishes nothing. Above two minute procedure is how
to start knowing what is - also called accomplishment.
Never flash a BIOS when hardware is unknown or unstable. BIOS code
has no relationship to your problem. Reflashing the BIOS is
recommended by those who use wild speculation - who do not know how
hardware works; therefore recommend replacing anything using wild
speculation. Flash the BIOS if willing to risk or permanently damage
the motherboard.
Get and post those numbers using a two minute procedure. Stop the
wild speculation.
I am pretty sure your entire post could have been summarized in about
one or two sentences.
