Copying Driver files

Hi all,
This might seem simple to you, but im trying to reinstall windows on a friends old computer, Its a epox ep-8kta2 motherboard running xp pro /sp2 its heavily infected and a new install is the best option. My problem is this mother board is not supported by the manufactauer anymore so after install i wont have a driver disk, the current installation is running dreadfully slow but still working. my thoughts are that if i copy the current drivers on the system on to a disk i will be able to reuse them after fresh install (will this work ?)If so how do i find these files ? .

Any advise would be greatly appreciated 🙂
