Troubleshooting Circuit Breaker Problems?

My home has partial power, I checked my circuit breakers, everything looks normal (I guess). How can I tell if my circuit breaker is broken or damaged? My basement has power and appliances work down there, but upstairs, my kitchen appliances and lights are out, and in 3 bedrooms, but I have power in 3 other rooms. WTHeck, I want to fix it myself, what do I do and how do I start?
