If the new MB uses the same chip set, you will have a chance with the repair. If not you may spend more time trying to remove the conflicting drivers, and may never work.
If you are going to attempt this. Un-install the chipset drivers prior to installing the new MB. Do it as the last thing before powering down. Then soon as it comes up install the chipset drivers. Then check to see what is broken. You may be forced to do a repair before you can install the drivers set.
The method i use is to boot win xp in safe mode, remove from device manager all chipset specific drivers, then reboot for a repair xp installation. Did it many times as i am responsible for the maintenance of friends and family members pcs. Only problem i had once was that i had not written down my xp key and the installation kept asking for it. Any other key i had did not work. It happened only once but it would be safer to just retrieve the key before any other procedure. Of course, BACKUP FIRST! After the installation, install new drivers (chipset first, vga second. All the rest can wait) and then perform a Win XP update. You can use Autopatcher XP to save time and hassle. Good luck!
