Unfortunately yes--I just gave it a try--same thing!
Downloadable manual for Intel DQ965GF is here.

Table 10 on page 43, gives a list of wake reasons.
AFAIK, S5 is the shutdown state (i.e. not Standby from the Windows
menu, but a request to shutdown, should put you in S5).
Disabling PME in the BIOS, would prevent any PCI bus devices from
waking the computer. That should include the LAN chip, if it was
on the PCI bus. I notice in the table, they mention the PCI Express
bus has a similar function called WAKE#, but I've never seen that
mentioned in other company's BIOSes.
The RTC alarm can be programmed by Windows, but I doubt the
Windows Scheduler would do something evil like set the thing
to wake up only seconds after a shutdown.
The Last Power State feature in the BIOS, should be set to
"Power Off". That way, when the power fails on the computer,
it remains in the Off state. You could try that as an experiment,
if you suspected the problem had something to do with the
machine confusing a shutdown operation, as a power failure.
Work through the manual, and maybe a few more ideas will come
to mind.
The last couple of times this problem has come up, it was the
LAN interface that was doing it, so I was hoping this would be
a slam dunk :-(
This could always be an actual hardware failure of some sort,
but there is a lot of stuff to experiment with first.
How much USB stuff is connected to the computer ? Could
you minimize the amount of USB on there, for another test
case ?
