Unable to turn on. Shutdown completely.
First of all, thank you Mayer. I'm deleted my question and your answer by accident. So I'll repeat my question. My mac shutdown and restarted about four times before shutting down for good. Mr. Mayer you mention that my power supply may defective. If I follow the iMac Intel 20" EMC 2118 guide what step will show me the lights? I have an iMac Late 2006 Intel Core 2 Duo Tiger 10.4.11.

You're right my question is confusing. I plugged in my iMac today. The light on the bottom didn't come on. No sounds either. No response when pressing power button. Where are these diagnostic lights? Are they on the logic board? My question of "what step will show me the lights" I was referring to the Step - By - Step Guide for the model A1207 with the 2.16 GHz Core 2 Duo. Also, I want to upgrade my Tiger 10.4.11 to snow Leopard 10.6.8. Is that possible and how do I do that? Thanks.
