Yes you can do a fresh install from an XP cd. Do yourself a favor and go into Device Manager and write down what harware you have (i.e. nic, video card, sound device) and then download the drivers and burn them to a CD before you blow away the partition and reformat. Usually you can find all the drivers from the manufactures website just by entering the machine model number. But most have variations of what hardware they offered in that model. That is where writing down what you have in Device Manager comes in handy.
