System Freeze ups

[Guest]

I am getting a system lock up very frequently and I don't know how to correct
it. To recover I have to shut off the power to the compluter. The event log
is showing:
AMLI: ACPI BIOS is attempting to write to an illegal IO port address
(0xcf8), which lies in the 0xcf8 - 0xcff protected address range. This could
lead to system instability. Please contact your system vendor for technical
assistance.

and:
AMLI: ACPI BIOS is attempting to read from an illegal IO port address
(0xcfc), which lies in the 0xcf8 - 0xcff protected address range. This could
lead to system instability. Please contact your system vendor for technical
assistance.

I don't know what this is. Can anyone tell me how to stop teh BIOS from
looing for the illegal port?
