1008? I would make a backup copy before of course.

I don't know if you saw my answer to your original post or not.
I propose you use the power monitor in the BIOS, to watch what
happens to the system parameters just before the machine shuts
off. That might give you an idea as to where the problem is.
You could have a CPU overheat problem, so watch the CPU temperature.
The PSU could be shutting off, and you might notice the voltages
from the PSU going out of spec. The CPU draws its power from
the +5V rail (as far as I know on an Athlon board), so watch
if the +5V is a lot lower than normal.
Don't be in too much of a rush to flash the BIOS. Every flash
comes with a degree of risk of a flash failure. Flashing from
a floppy is safer than flashing from Windows. But now, think
about this - if your computer is not stable - say you start to
flash and the computer shuts down before you are finished.
What will you do then, when the flash chip is corrupted ?
Do some investigation first, before jumping to conclusions.
If this was my problem, and I didn't have recourse to any
measurement tools at all, I would start by removing the CPU
heatsink, and applying fresh thermal paste. I would make sure
the heatsink was installed properly, not tilted or rotated
from the proper position. The square of metal on the bottom
of the heatsink should align with the center of the silicon
die - if it doesn't align, then figure out why.
After improving the contact between HSF and CPU, if there was
no improvement in symptoms, then it would be time to try
another power supply.
BIOS flashing should only be attempted if the computer is
completely stable. An unstable system is a poor candidate
for flashing. Just like, don't attempt flashing during a
thunder storm
The power will go off in the middle of
flashing for sure.
