Rats ... I mean I'm glad you already have XP SP3!
Well, I'm reaching here but is this the original hard drive or have you replaced it with a newer one? Perhaps find an older hard drive?
Does the MB have the latest BIOS? You said you don't have a floppy ... I got one of those usb floppy drives cheap ... works great for stuff like flashing the BIOS when there is no floppy.
Wish I could be more helpful!
