Before jumping to formatting WindowsXP, make sure you do other things before. This seems to be a simple problems and would be a waist of time to format WindowsXP for this. First, when the computer is on, press on the Eject button on the CD-ROM and see if it opends. If ok, go into the Device manager in your Control Panel. Click the "+" beside the CD-ROM line. If you see your CD-ROM, right click on it and then Uninstall. Restart the computer and have WindowsXP reinstall the drivers for that CD-ROM. After you get back in and Windows still hasn't detected your CD-ROM, I would go download a spyware remover such as Adaware or Spybot (both free). Let us know how it goes.

Wow, I totaly ignored the subject. It isn't software related. I'm sorry, I was excited to write an answer, I didn't fully understand your situation. Ok, forget everything I said and follow jhon's answer. Abit AN8 Socket 939 AMD64 3000+ -1.8Ghz Corsair 1Gig 2x512 Seagate 160Gig SATA MSI Radeon x800 PCI-E Antec TrueControle 2.0 550 Watts
