System freezes, Event log: ACPI Bios, invalid Portaddress

[Sebastian]

Hello.

My system always freezes, no matter what I do,
sometimes when starting, but mostly when normally
working. Opening Explorer, Scanning for Viruses, a.s.o.
Last week I installed a new version of WinXP SP1 and I hoped
it would stop. But no..
Today i bought a new power supply (300 W, before 235 W).
I have an Athlon 1,2 Ghz running on a mainly office pc.
That means, no big gfx cards, a.s.o..
Now it seemed, the new powersupply had solved my problem,
but when I just stared my Virusscanner (Antivir),
the system again freezes after 2min44.
The Eventlog has the following errors logged:

"AMLI: the acpi Bios tried to write to an invalid EA/Port-
address, which lays in 0xcf8 - 0xcff, which is a protected
area."

There are one following event with same msg and two
following with same msg, but other memory region.

I can't explain myself, what is always happening and what
could raise the error.

Is there anybody here, who knows the solution or even
has an idea?

Thx alot!

Sebastian

Try to update your BIOS.

I have done that this morning.
Chaintech Board, Latest BIOS available.
Still hanging, just two min ago, first
with Mozilla, then with IE, both times
the same..
I move my mouse and -> hang.
I have attached my Logitech Optical now
to an USB Port (before PS2 Adapter), but
that seemed not to help..
