I have an iMac... one of the round ones with the moveable flat screen on the neck... with an 80gig hard drive... I bought it in Dec 2003. It works fine. It only has 7 or 8 gigabytes of space left on the drive. And I run 10.3.9
I probably only shut it off once a week or so. SOMEtimes, when I start it up, it goes "DOOOOOOOO" in a high pitch for a few seconds, then a few seconds later I get the normal Mac start up "DAAAH!"
What is going on?
