I tried upgrading to Mountain Lion on my MacBook Pro. I was running 10.6.8... heard a ringtone then the screen went black. System is off and won't restart. Can anyone help?

MacBook Pro, OS X Mountain Lion (10.8.3), installation

    Where were you at in the install? Was it restarting after downloading the updgrade, but before starting the install, or had the install already completed and it was restarting?
