My sisters computer keeps crashing. I think its caused by this error message

AMLI: ACPI BIOS is attempting to read from an illegal IO port address (Oxcfc), which lies in the Oxcf8-Oxcff protected address range. This could lead to system instability.

I flashed her bios to the latest yet im still getting the error and it keeps crashing.The mobo shes using is a fic az11
