Is it a common bug, that the screen turns blue and textures become missing indoors in Fallout: New Vegas? Is there a solution?

Solution 1:

This is just a guess, but I would bet that your video card is starting to break. Being that you have the original 60gb and its lasted this long, I wouldn't be surprised at all. My original 60gb broke about 5 months ago, and you have to remember you are treading on new ground because no one has had a ps3 much longer than you, which might explain the fact that there is little info about this problem on the web. Also, it taking 2 hours to start showing blue textures means it could be heat related. What happens when you start up the game when your ps3 has been off for a few hours?
