Go to your computer manufacture's support web site
and check for Windows XP drivers for your specific computer model number or motherboard.
Note: If there are no XP drivers listed then your computer may not support Windows XP.
If there are Windows XP drivers, then download to a folder on your hard drive and burn them to a CD/DVD.
Then after installing XP install all device drivers, starting with the Motherboard/chipset drivers,
SATA, LAN, Audio, USB, Etc., and so on.
