Sherlene, I have the exact same problem. Looks like it's very common. I'm 35 hours in and been in and out of the Strip several times, now it won't load, even on save games that are 5 levels back. goes through the loading screen, then to black and frozen console. Will I restart? Not a bloody chance. I've been a Fallout fan for 10 years and love New Vegas, but this is unacceptable.
