Where is a good place to explore for some info on careers/majors involving computer science or psychology?

I'm kind of discontent with my current major (Business Management), and want to switch for my next semester to something more interesting to me. I know there are some helpful sites that have information on majors out there.. I just don't know where to find them. lol.. Also, I really wish my high school guidance counselor put more emphasis on this, it would have been very helpful to research back then.. Instead of know during my first semester. Better late than never. haha
