Macbook problems?

Question

I recently bought a macbook (about a month and a half ago,) and everthing was going well. But, ocationally, i can't wake my mac from sleep (I know frontrow can cause this, but there have been times when it wasn't on) and a day ago, I was viewing pictures or something, and every window I had open slowly got the spinning disc icon. Eventually, I lost mouse control, and the whole thing froze up. Anyway, I used the power button to restart the computer, and when I logged in, all my appearance settings had been reset, from the dock to folder options. Also, applications reacted as if it was the first time they had ever been opened. But all my applications I had installed and my files were intact. I later put my computer to sleep, and when I started it again, it did the same thing. I had "sleeped" it once or twice sice then, and it is working normally.what could have caused this, and how can I fix it?
