Motherboard BIOS needed for K7VMA

Does anyone know what the position is with an Acer K7VMA motherboard please?
I have one and it SEEMS TO need a new BIOS. The one on it dates back to 2001
and the computer has started booting into Windows 2000 and then shutting
down, booting into the POST screen and then shutting down again. I dont use
EMail so I dont think it is a virus problem (though I have seen viruses or
trojan scripts which make a computer act a bit like this)

Sometimes I can leave it off for a while, boot into safe mode and then into
normal mode (although networking has mysteriously stopped working but unless
someone recognises these symptoms I suppose I can try to rectify that
later).

Acer says that Aopen handles their mothboards and peripherals but Aopen
denies all knowledge. Acer then says that this is made by a company called
ECS but they dont seem to list BIOS upgrades on their site or the ones they
do dont seem to be BIOS upgrades, merely sound and video driver upgrades

Has anyone had this problem and I am wondering why all the mystery on this?
Or is this just an extraordinarily well designed BIOS which doesnt need
upgrading?

The problem doesn't seem to be in the power supply itself:

Curiously enough I got this computer with a blown 350 watt PSU and put a 275
watt one in instead to get it up and running. The whole computer (even the
outer casing) has been running very hot when left on ever since then: (And I
am not using anywhere near 275 watts according to the various on-line usage
calculators)

Do you think something like bad caps is causing it to blow and must I now
dump this MoBo? Seems a pity as it has a 1.2 HGz AMD CPU whereas the
fastest other one I have is a Pentium 111 733 I cant imagine the processors
are interchangeable.

I have noticed that I can leave the unit to 'cool down' (from being only
slightly warm) and it will then start up to the op symptoms. On a second
boot it, again, wont get any further than the POST and thereafter, again, it
won't even get as far as that. Does this sound about as quick as leaky caps
start to malfunction in use?
