I had posted previously about my 20" 1GB iMac shutting down when doing anything with a CD/DVD -- thought the problem was solved by switching the computer over to another electrical outlet. This is also after taking it to a Genuis and them not being able to replicate the problem. Well, the iMac is doing the same thing again. I cannot import from a CD, burn anything, etc. It also freezes quite a bit of the time if I have, say, iTunes and iPhoto both running -- but I am assuming this is because of the intensity of the apps running. I am now wanting to just start over with a new iMac, but I am out of the 14 day return period. What are my options? Is Apple good about assisting customers whose products appear to be defective within 30 days of receiving it? Paying the restocking fee would be well worth having a machine that works reliably.
