Help with Dell Desktop computer XP install needed?

Just recently my hard drive crashed, thankfully I had all my information on a second drive which is perfectly fine. I bought a new SATA hard drive and am trying to install windows xp on it. The computer is a Dell XPS 400. Whenever it starts, the files are being loaded, I get to the screen where it says press enter to install windows. I press enter and it goes to a screen that says "Setup did not find any Hard disk drives installed in your computer". I followed the instructions on this website

which says to download and install nlite and then create a custom install file in which you can load up the drivers yourself. The main problem with that is that I can't find any drivers that nlite can recognize to add to the install. So if someone can tell me where to download all the original drivers for the computer (I checked on dell.com but couldn't find it, and again, whatever I found *not originals* weren't detected by nlite). I even changed the new Sata hard drive for a new one if there was a problem with it but again, same result. Again, the message I keep getting is that "Setup did not find any Hard disk drives installed in your computer". Is there anything that can be done?
