tell about the xp cd, is it the full retail version, upgrade, oem or a recovery? Do you have your boot setting with cd first?
when you boot, after power on try tapping the space bar several times until you get past the post. There should be a press any key to boot from disck when a dvd is loaded at boot but for some reason it does not always appear.
finally if the above does not work, what about the cd drive, when you power on does any lights come on it? if not, recheck its cables.
