Does it start reliably, with excess electrical load removed ?
(Unplug the hard drives and CDROM and see if that makes
a difference.)
A hard drive can draw 2 to 2.5 amps for the first 10 seconds.
During this time, the video card is not running at full power
(maybe 30% of full load). On my processor here, the BIOS operates
the processor at about half power during startup. So while the hard
drive power may look bad, some other things are not as bad. As a
general rule of thumb (a guess if you will), startup should be OK
with up to four hard drives. For more than that, you should do a
more detailed calculation of power at startup and max running
(say gaming or running 3DMark). In other words, if you had 10
hard drives, that might "tip" a power supply over the edge.
If you get into Windows and run a heavy load (3DMark of some
version would be a test case), does the benchmark complete ?
Can you run Prime95 for any length of time ? Those are examples
of things that might draw a decent amount of power while in
Windows.

I wouldn't generally reach for the BIOS update, unless
there is some evidence the instability is due to the
BIOS. Certainly, you wouldn't want the machine to
crash in the middle of a BIOS flash update. Try to
investigate the machine as it currently stands,
and see if you can gather enough evidence to point
at the busted part.
