Problem with Restart

I downloaded Mountain Lion, installed it and then my computer restarted. Everytime it brings me to the log in page, it tells me "You shut down your computer because of a problem. If you want to open the applications that were open when you shut down, click open. If you do nothing, the computer will continue log in." When I click open, it brings me to the homescreen, with Mountain Lion installed, for about 30 seconds, then immediately shuts down and restarts again, giving me the same error. If I do nothing, it just shuts down, restarts and gives me the same message. I've tried doing a hard shut down by hitting the power button, but no help.

Same problem on an Imac (2010) & rMBP (2012), with a Kernal panic error as well.


I have Applecare on the Imac so phoned up the support guys, they advised me to, unplug the power cable from the back, do a PRAM reset and remove all the USB connections from the back.


Once i had done the PRAM reset it finished off the installations, strange it happened on both machines, including one that is less than a month old.
