My 2008 2.8 octo wont start. Been having sleep problems which seem to be getting worse the longer I leave the MP in sleep mode. Put the machine to sleep 10 hours ago and is now completely unresponsive. - Unplugged all leads to reset SMC. - Started up with only keyboard/mouse and both ACDs attached. - Removed all OWC memory leaving just the 2x 1gb apple ram. - No start up chime so cant reset PRAM. - Power light comes on and can hear a few very quiet wirring and ticking noises so assume HD is trying to do something. Fans come on also. - Router light for this machine comes on but stays orange just like when its asleep. Not able to use start up disk because drive tray wont open. Is there a way to open tray when machine is for all intents and purposes switched off. I am assuming the worst. Anybody got any other suggestions.
