All of a sudden my MBPro won't start up. I get an error message saying "your computer restarted because of a problem, please click on a key or wait a couple of seconds and proceed". The message keeps recycling over and over. I tried shutting it down and tried to restart it but keep getting the same message. Now the display just turned to a blue/light blue/ white pixel page. This an older (2008) MBPRo with Maverick and updated ram. Any ideas?
