Your hard drive probably doesn't have the right drivers or something for this new motherboard. Back up everything, and do a reformat/reinstall of Windows XP:

When windows is installed to prevent piracy it registers that version with your bios chip so if the bios chip changes then windows then has to be reverrified or reinstalled in order to make it work. this basically just prevents people from taking a hard drive out of an old computer and sticking it into their one and running windows off that. it sucks when it comes to things like swapping your motherboard but there isnt much else that can be done about it. perhaps microsoft will be smart next time and change that
