Is your new BIOS set for ACPI power management? That will cause Windows failure. It's unlikely your 4 year old setup had it. Shut off all power management and see if it won't boot.

I repeat - If you installed XP without power management that is what XP expects to find. ACPI power management assigns very low level hardware interrupts to control all sorts of things. An old BIOS version from 4 years ago most likely didn't handle ACPI. Turn off all BIOS power management, turn on PNP power management ala Window98 only. IF this is so then you would not need to reformat nor reinstall.
