Thank you for the extensive reply, i will check the things you've mentioned.

The corrupted save files, was a one time thing. I just replayed from a good save.
But the game still crashes on every loading. I disabled steam sync so i can quickly reboot the game to continue.

I did find out that i have a faulty RAM, got few blue screens this week, wich is probably what started the problems in the first place. I am getting new RAM soon and will see if the problems persist.
If they do, i will check off all the options you gave me.
