Hi! I bought a white macbook (with default specs, 1GB) around September in 2006. I bought it with my scholarship money that I earned over the summer. Anyways, now a days.. the macbook gets hot fast and the fan starts making sound (just like when you turn on a normal fan, that breeze sound). Can I take my Macbook to the Apple Store and get a replacement? Perhaps, a C2D Macbook? I didn't buy AppleCare though. Thanks!
