iMac Wont power up.

[momentum300]

Hello,

I have a 27 inch iMac 2006 I believe...anyways I plugged it in and nothing, I tried 3 different outlets, press the power button and nothing. I have reseated the DIMM's numerous times, I have reset (or tried to) the SMC. This Mac has not been used for a year so it sat on my desk unplugged. What is the likelihood the CMOS battery is dead? If it is the battery does anyone have a link on how to open the iMac up so I can change it. Or does anyone else have any other thoughts? I can't imagine its the logic board or power supply...Its just sat and hasn't been moved or used. Also the last time it was used it worked just fine. I had purchased a MBP and that became my primary use computer which is why the iMac sat for so long. Thanks for any help

Did you do a PRAM reset? http://support.apple.com/kb/ht1379

I am not sure this is possible because of the fact that the computer will not respond to the power be pressed at all. Am I wrong to assume this? I have tried other peoples ideas of hold the power button in for 10 seconds and such.
