hey all....this is my first post ever on here so bear with me. So if i start up new vegas and you start out in the docs place it'll work for about a minute then things start to black out in the buidling. You can look around and the picture will flash back on but certain things will still be blacked out. if you want to see what i am talking about check out this link.....i just wonder what i should do

I have tried returning the game for a new one....reloading the game data....changed out the hdmi cord with a known good one....changing the resolutions to 480p and i did download the patch nothing has worked. Uncharted 2 works fine and as far as i can tell this is the only game that does this. It does not freeze my ps3 if i can manage to find my way out the door through with the game screen flashing on and off then outside everything seems to work well.
