2012 Macbook Pro freezing up and giving the pinwheel all the time.

Last week my macbook pro started freezing up whenever I am doing something. Whether i am just surfing the web, going through my folders, or in photoshop it just starts freezing up. When i have pandora the audio will cut in and out saying that shockwave has crashed. I went into my activity monitor and everything seemed to be normal, no applications taking up to much memory. Then i ran a complete hardware check and nothing was wrong. I then reset my osx and it took almost 24 hours but didn't change everything. Then yesterday i repaired my disk permisions and that fixed it. For a couple hours and now i am back to having my computer freeze. I am currently running osx 10.8.2. Anyone have any ideas on how to fix this or should i just take it into the apple store and see if they can help?
