Yeah..... so now, I loaded 7 saves back and it was good. No crashing while fast travelling. But now, it crashes the game while... just playing normal. I was decorating my house after 10 minutes of playing, and then, magically game crashed again. The answer is, I think, that my PC is em,,, how to say.... ''Totally Destroyed" By this I mean, that I restarted this PC system 2 times, cause of viruses, and other games dont want to work. Battlefield - no connection. Rome II - kicks out after 5 minutes. Skyrim - on very low graphics the game crashes also.
I think I must reset PC 3rd time.
Thank you all for your help. You really helped me.
