Turned on the iMac a little while ago for the first time in a week (we were away). After it was turned on for about 10 minutes we heard a SNAP! sound, the screen went black and the iMac was dead. Can't turn it on at all. It was plugged in to a UPS which is still fine; there are no power problems. I tried plugging it directly to the wall socket just in case, still dead. It almost sounded like a static electricity "event" but nobody was actually touching the computer when it happened. This is an Intel iMac 2.8 GHz, purchased late November 2007 from apple.com. So it's out of the 90-day tech support period, but within the 1-year warranty. I got it with 1GB of RAM, but installed 4GB of Crucial RAM later. Unfortunately, I had no backup drive installed yet (that was in the works), but I really don't have much on the drive yet, so not a big deal for data loss, if it came to that. So, what's the procedure? Do I call Apple to arrange for an appointment to take it to the Apple store (about 20 miles away)? Do I call the Apple Store directly? I don't want to be charged for any tech support on this.
