Depends on what direction you want your computer carer to take. There is A+ certification, Network + (if its still around) MCSE (Microsoft Certified Systems Expert), CNE (Certified Novel Engineer). Those are just ones off the top of my head. If you want to deal with mostly Hospitals and large file servers you will need to learn Unix and the AS400 file server. Some companies use windows based file servers (The University Of Toledo is all windows [my dad works there]) If you want to deal with mostly consumer based PC's the Microsoft Certification would be the place to start.
Edit: I have the official coursework for the MCSE training program ( the books are a few years old though ) I haven't had the time to actually study it yet its a large course and I wish you luck in your endeavors. Hopefully if I ever get back to school I will finish my degree.
