Error Reinstalling XP

My sister recently gave me her Dell Dimension 4400 with a 40G Maxtor drive and 128m. I added a USB 2 card, and an additional 512 of memory. There were no problem with either of these upgrades. I then reformatted the disk and tried to reinstall XP Home with the original Dell installation disk. Everything seem to be going well until the Installing Devices process. I then received a "Device Installing Error" Windows could not load the installer for CDRom, contact your Hardware Vendor for Assistance. I received the same message for the "DiskDrive" and "Battery". I clicked OK for each message. The process continued until I received another error message. " Can not Install this Hardware. There was a Problem Installing This Hardware: "System". Error Occurred During the Installation of the Device. The Data is Invalid." Setup ceased and then looped back to the installation process with the same result. I have tried reformatting and installing only to have the same result.
