i have a Macbook Pro mid 2009 with 4 gigs ram and a 750 hybrid Drive...I will get from time to  time a circle with a line throught it and the apple would flicker and then go into the Mt Lion Recovery mode ..I would run the verify disk and it would be fine ..i would restart it and then it would run fine for awhile.them every once in a while it would do it again and i would do the same thing and the results would be the same...i am running a hybrid drive in my Imac 2.4 fine with no problems..The ram is the orginal that came with this .....the problen is it seem to be unable to find the startup disk but then it will run fine for quite awhile...i was thinking it was the ram going bad but the reports were fine..a few times it would show a kernal crash report..i would restart several times after ...about 7 times with not problems... firmware it up to date and right..that just leaves a logic board issue..which i hope not
