Russ,

This could be an issue because the computer is fairly old. Windows 2000 and 
later require by default that the BIOS support ACPI in order for them to be 
able to power off the computer. ACPI is the preferred interface for 
interrupts and such, but older systems may only support APM.

While there may be a BIOS option to enable ACPI, older systems may have a 
buggy implementation, which may cause problems. Also, just turning it on 
takes special handling to do a "repair install" of WIndows XP because ACPI 
requires a different HAL. While Windows 2000 had no other option to solve 
this but to change to ACPI in the BIOS, Windows XP has a built-in solution.
