Hi, I had the same problem. The game was also constantly crashing. I also thought that the problem was in Psu, but it turned out that my PC wasn't so powerful. Then I, of course, found pc optimization software, cleaned up the computer, set up the system and everything went like clockwork. Now I calmly play the game, and it doesn't crash at all. I see that your problem was different, but my reply can be useful for somebody.
