Check the manufacturer's website

Your best bet is to look up your computer model from the manufacturer's website and see if they have installation instructions and the drivers you need. You'll probably want to look through device manager to see what hardware is on your machine so you can see what drivers to search for. It shouldn't be too difficult but count on at least 30-45 minutes to install XP and probably another 30 minutes to install the drivers and then at least another hour to run all the Microsoft updates. Also, make sure you know how to reconnect to your wireless router so you can get Internet access to download updates. You might consider downloading all the drivers beforehand onto a USB flash drive. Good luck!
