Can't bootup..stuck grey screen
I could go to openfirmware mode, and also I could use mac os 10.5 CDs to proceed to a certain point where "cannot be installed on this computer" comes up... at this point, I could use disk utility to at least see my HD model/serial number, but it says not mounted.
So my question is,
based on the above symptom, what's the likelihood of this being a logic board failure?
(I'm asking this question because I've tried swapping to a new hard drive and the same "cannot be installed.." message came up).
If diskutility at least identifies my HD, is my logic board OK?
Thanks in advance for any advice.
-genius bar sucks
Is this a good question?
