Earlier tonight I was ripping a CD in iTunes and it I had to force quit it because it was not responding. So I looked up on the apple discussions and I already reset my PRAM and my PMU and I also did a hardware test and at first it gave me a RAM error so i opened it up and I swapped the RAM. I retested and everything was fine. And no one has responded back to my plea for help. Should I give apple care a call tomorrow or should I just bring it in to the Genius Bar at the Apple Store? Any help would be greatly appreciated.
