[joe]

I don't why sometimes unable to boot up my winxp....my
error message in event viewer is show as below:

EventID: 4
Source: ACPI

%2: ACPI BIOS is attempting to read from an illegal IO
port address (%3), which lies in the %4 protected address
range. This could lead to system instability. Please
contact your system vendor for technical assistance.

Can anyone help me how to solve this problem?
