So here are the symptoms of my MacBook (had to edit the message because I noticed that i wrote iBook and not MacB ook) whoops......bought it late December 2007. So here's some of the things that are going on w/ it: 1. Anytime I watch a youtube video the fan comes on - it's a very whirly sound - it's so loud. At times the fan comes on and makes the whole thing vibrate. Also, after a couple minutes it goes off because it seems that it's loosing power and seems to slow down. 2. Yesterday I tried to burn a CD in itunes and after 1 minute the time indicator (time left) just started getting bigger and bigger to where it was telling me it would take 30 minutes to burn the CD. Again, the iBook started vibrating but now it seemed to come from the CD drive. I'm scared that it's going to crap out on me and leave me w/out a functioning system... Any thoughts?
