Hi Experts -- I have an iMac here in the shop that is showing the question mark folder icon when it turns on. I am unable to access the diagnostic utility by holding down the D key during startup as I typically do. I can, however, get it to boot to a Snow Leopard disc but none of the diagnostic utilities are available (greyed out).
Any thoughts? I have some suction cups coming in the mail so I can take a look at the hard drive and connections and I'm hoping that's what the problem is.
