Is computer science right for me?

I'm not tech savvy, but I do enjoy using computers. I guess the reason why I want to do computer science is because I want to know more about how they work, and why they do the things they do. I don't know anything about Java or C++, but I do have a brain that's willing to learn and grow. Is taking Computer Science a good idea? I don't really have any other majors here that interest me.
