It is the most current white MB.
I don't recall excatly what I did.... Just normal use. No system type installs/changes/etc. Normal meaning playing music and writing a document in Word. Then when done, just "Shut Down."
Yes, I have the Install DVDs. Was thinking about installing OS again.
However, I just realized that the easiest thing to do is to take it to a genius at the Apple Store. 🙂
Thanks
