OK - Well, you said you have a new full install Windows XP CD with the license so you should not have problems installing it.
Do a full format, not a quick format when prompted and format in NTFS which is far better than Fat 32 for XP.
By the way, if you are going to use a Sata hard drive make sure your motherboard supports sata and has the proper connection for it or you have an expansion card for it and have the sata driver ready to install when you are prompted by the Windows installer. It should be on a cd that came with the motherboard or the sata controller expansion card - whichever applies.
Ignore the above if you are using a regular hard drive that connects to the IDE ribbon cable the old hard drive connected to as a replacement for your old hard drive.
Make sure your new hard drive's jumpers are set for "master" (or primary) which they should be by default out of the box.
Be careful to ground yourself to the computer's metal frame to discarge any static electricity before you start touching anything inside the computer.
