Asus P5GD2 Deluxe, latest BIOS. I shut down from WinXP and a few sec. or a
few min. later it powers back on. Then when I turn it off from front power
button, it always stays off.

All of the "wake on" events that I can find in BIOS are disabled. What the
hell do I do next? Thx!

Uhmmm maybe is it a cousin of HAL 9000?

Ok, sorry.

Probably there is a wake event software that still you didn't find.
Also you could try reinstalling the operating system, this could bring
some options to default.

Check in the BIOS that wake on LAN is not enabled.

Assuming Windows XP: Go to control panel > Power Options> and check all the
setting there.

Check the little power connectors.

Maybe the wrongly connected.

Like power switch and led and stuff.

Skyboy, stick to what you're good at, abacuses and the like.

:) Well I checked the BIOS again for every single setting I think; still
nothing. Incidentally, I did recently reinstall XP and that's I think when
the problem began! Thanks...

Actually I'm pretty sure that's it, since I disconnected the lan cable and
the problem went away. But I can't actually find the LAN wake setting! I
see the list of other wake events (ps2 keyboard, etc) but it's not in there!

Any wake event for (pci) cards might be the culprit. Switch them all off
to see what's the problem.

Maybe Windows programs the LAN chip, just before shutdown, for any required
behavior.

If I go to Device Manager, and look at my NIC, there are properties
in there, saying "OS controlled" for Wake on LAN. That dialog says my WOL
is currently Disabled.

PME is used by the actual NIC chip, to signal to the chipset, to wake up.
(PME is the same kinda thing they used to put on that three wire WOL cable.
Now it is a bus signal.) The NIC chip runs off a derivative of +5VSB, to
get the necessary power to look for Magic Packets or to look for "any
activity". Some NIC chips have multiple waking methods, while others
are quite restricted as to what will wake them.

Yes, thank you, that was exactly it! I'd even diabled that once before but
a long time ago. Anyway it finally stays off now! :) Only question now is
why my router/modem would be sending magic packets after every shutdown...

It probably isn't. As Paul said, some NICs have several methods of
'waking' the system, so it could just be any activity on the port (eg
the modem/router simply seeing if there's anything there.) You could
test that with a cross-over cable direct to a 2nd PC, for example.

HTH,
