What should I do when I quit the game? (The Elder Scrolls 4: Oblivion)

Well, actually, that's all, it freezes on exit, the image freezes, the sound that an error has appeared like the program is stopped, but even alt + tab does not help, only a call to ctr + alt + del and it’s not a fact that it will collapse, most often ends with the fact that you have to reboot the system. In the beginning I played on the xbox 360, I recorded it a long time ago, but I started playing only now, in the end I caught a bug there, the Oblivion gates did not close, I downloaded the pirate, none of it started, I already spat on the incentive, and fuck the problem with this fucking exit. My hardware is I7 2600, 16GB RAM, GTX 980ti, Windows 10 Pro license (compatibility doesn't help). This game is that really oh ** la ???
