Have you checked the mac site to make sure there are no recalls on anything in your computer? Does happen from time to time?

Is there a 12 month warranty on the computer itself (I think there is but I could be wrong). Could be worth calling mac and asking them. Might be a simple fix and they may just tell you even if you no longer have the phone support.

I have a vague memory that my ibook did that at some point, I so cannot remember what we did to fix it. I remember stressing out about repairs etc, but was all good in the end. I will keep thinking on it.
