I did a clean install of mountain lion on a 2010 macbook pro. specs are 2.66 ghz 8 gb ram 750 gb 7200 rpm hard drive. 256 mb 320m graphics I left and came back to my computer to a message saying there was a problem with the computer and it had to restart. this happened 2 more times in the last 2 weeks since ive installed mountain lion. there really isnt a whole lot of info other then the message there was a problem and it had to restart. so I dont know what it is or what is causing it.
