    My iMac 9,1 early 2009 is in the shop with Apple now because it would not start without using Safe Boot after I had installed Mountain Lion. Apple Genius Bar rep tested, HD Ok, reinstalled Mountain Lion, no help. He then wiped the HD, reinstalled again. Sill would go dark after the start-up wheel stopped. - He felt it was the graphics card causing the problem. After getting home, and doing some Googling, I started to encounter some articles about 32 bit - 64 bit issues with some of the older installed cards. I had the NVIDIA GeForce GT 120 256 MB installed in mine. Does anyone have access to a resource confirming whether that particular card is or is not compatible with Mountain Lion ?

    Any Core 2 Duo or newer iMac with anything other than an ATI X1600 GPU can run Mountain Lion.

    If it is the GPU I'd suspect it's not how powerful it is - I'd be more inclined to think that it was failing rather than some other componant. I had graphics anonamolies with my old Core 2 Duo iMac. I wrote about it in depth here if it is any help: http://goo.gl/0Woyl6 ...it might help you diagnose the problems at least - the Apple store I kept going back to were next to useless.
