Loretta's Apple computer keeps "beach balling," and hangs up. This is OS X's way of saying that the computer is busy. If it's there for a long time, something is holding the computer up like a bad program or a failing hard drive. Most likely, there's a bad sector or two on the hard drive that's causing it and it could be the beginnings of a failing drive. Leo recommends going to MacSales.com and getting a new hard drive. It should be pretty simple to replace. Loretta should backup her old hard drive first.
