I have an early 2011 MBP 17 inch laptop running Mountain Lion. It freezes up suddenly even when the only thing is opened is just a browser with one tab. I uninstalled the operating system and reinstalled it but it continues to happen. I ran the verify disk and found no errors there. sometimes the computer freezes at boot up in the grey screen before the login prompt. Any suggestions for a fix?
