Forum:Some problems with people and monsters?

Hi, I recently purchased Fallout 3 and had a good time on my pc. However, today I had a strange problem. Everyone, npcs and monsters, have problems with animations. First, instead of walking, they float around. When the sit, they just kind of lie down in a slanted position. When they look at me, their heads turn around in a 360 rotation. When they attack, they stand there and I take damage. At first, I thought I could live with it, but now I'm having trouble with looting and main quest stuff, like when someone runs up to you and talks to you. Please help me out and thanks in advance!
