News of Power Management problems

Hi

I am running XP Professional and my system keeps crashing without warning and it is really P*****g me off !

My event viewer gives erros at the time of crash as follows:

AMLI: ACPI BIOS is attempting to read from an illegal IO port address (0x4d1), which lies in the 0x4d0 - 0x4d1 protected address range. This could lead to system instability. Please contact your system vendor for technical assistance.

and

AMLI: ACPI BIOS ...

I am getting an event viewer error
AMLI: ACPI BIOS is attempting to read from an illegal IO port address (0xcfc),

Microsoft indicates that I should get a BIOS update.

I have

Award Modular BIOS V6.00PG
Bios ID: 12/06/2000-8363-686A-K7VZMC
Chipset: VIA 82C305 Rev 3
Bios Eval: K7VZM Ver 1.1g 12/06/200


I am unsure of what to do from here
