Hello fellow Wastelanders!

Please take a look at this video it shows you whats going on with my STEAM copy of the game

For those who doesnt really bother alot to even watch the video, ill explain it
At some areas in the game. Like " The tiny store/house " Outside primm (South) When you head for Movac outpost or Whatever my game freezes and the sound goes reapeating like " d-d-d-d-d-d"
This also happens at Gibson Scrap yard. Only when i get close tho so the main thing it crashes when the game starts to like render/spawn diffrent elements of area. Or something. It only happens at those points at the moment since im stuck at these areas i dont
feel like moving on, since im a really Fallout Lover and id like to complete it all. I really hope someone knows anything about this

I have also looked around this forum for like 20 pages and ive found nothing So all of you who knows something dont be a lazy bum and help me and the other with these problems thanks! :D:D
