Thanks to all of you that chimed in with advice. I really appreciate. I took my iMac to the Apple store yesterday. Here is the culprit…
I have 8GBs of RAM installed on my iMac, and both of the Centon 2GB RAM cards are bad. It was as simple as that. I’m put off that both of the Centon RAM cards that I purchased the day I got the iMac are bad. They didn’t have a 2GB RAM card in the store. I could have taken my iMac home, but I left it there because I didn’t want to lug it back-and-forth for installation of a RAM card. It should be installed and ready to come home on Monday. My momentary “What the Hell Apple??!!” feeling quickly subsided. I should have known better.
Update: I finally got in touch with Centon, and they are going to replace both cards. Hopefully the new ones will work. If not, I’ll press for a refund and go with Crucial RAM
