I do not know what your friends mean by "talented with computers", however, being talented with computers is very impressive, versatile and useful.
I am on my fourth year as an electrical power engineer (5 year masters course), and I am currently involved in a pretty comprehensive school project with several other engineering students. The two from computer engineering are literally magicians in my eyes, and I can assure you, I am among the very best power engineers in my class; still, the practicing of dark computer arts fundamentally amazes me. The same goes for the two from electronic engineering. What they can do is beyond my regular reference frame, and thus it is awesome :-)
I am guessing you are quite young, so your talent is still in the making. However, if computers already interest you, and you seem to have a sense of satisfaction from working with them, I suggest you try to immerse yourself a little in them, to see if they may truly be your talent.
Try to learn a programming language. Tons of books are written, typically "a beginners guide to this and that language". In my opinion, Python is a good place to start, as the language is powerful and tons of online resources exist.
Good luck! - Ghini
