Hello, before i write something, sorry for my bad english.

I got original Fallout 3 GOTY Edition for PC. All was good until i exit Vault 101. When i was in Vault 101, i just play and nothing happened, 1920x1080 and another things. When i exit Vault 101, i got a problem. Game start freezing [i can jumps and i hear that, but screen its absolutely freeze (and my windows after alt+tab looks like rainbow - colors are changed, 640x480 resolution and another)] I'm still ahead Vault 101, because i can't play with freezes and crashes.

Sometimes freezing stops, but another problem is crash. If it isn't freeze, i got crash to desktop without any information why. I don't know what to do, i tested many options, but doesn't work. So for now, please help me.
