Guys,
I really need help with some diagnostics on my iMac (late 2009 27" iMac)I'm about to the point of taking it in to a professional, but I'd like to get some thoughts on what may be the problem. When I attempt to power it on, it makes the chime, and then the screen may or may not light up. If it has been several days since I messed with it, it may go ahead and boot up and work for 2-3 minutes and then the screen goes black and its done. Once you have powered it on recently, then the next time you do it, the screen won't even light up (but it always chimes). I have removed the ram and tried it one stick at a time, and that doesn't have any effect. Am I looking at a bad motherboard, or perhaps the processor? Any thoughts?
Thanks for the help,
Brian Grossman
