Initially I thought the HD had died. Then I realized that it must be the power supply because I did not hear the familiar fan sound that it makes when I turn my Mac on.
I then pulled out my iPad and searched for an independent local Mac repair person – and I found one that makes free house calls. I left VM for him and followed up with an email. He called me back this morning and he concurs that it probably is the power supply. Unfortunately he is in Vegas on vacation and won’t be back until next week. He said he could get another local person on it if I HAD to have it fixed ASAP and I said that with my iPad I could hold on. So next week he contact me and we will set up a time for him to come over and he will bring a new PS. Then I thought that while he has it open, I might as well upgrade my memory since I don't have a lot and when I have iTunes, Photoshop, and several other apps open at the same time the machine can really bog down.
I figure IF it is really really dead (in case the HD failed), then I might be asking getting a new iMac: I know I could just put a new HD in but the Mac is over 5 years old and I would just sell it on ebay at that point. Though I don't really want to be spending at least a week of evening restoring all my stuff from the backups I have - yes I have an external HD and I use time machine to make my backups.
Who is the guy I called? Here is link http://bradfordredding.com/ Yes, he called me back while he was on vacation. That is good service!
