Computer keeps crashing

Hi! My game keeps crashing my entire computer. I have already repaired the game multiple times, changed the game visuals from ultra to high, and uninstalled and reinstalled the game. I also have no cc or mods installed. This didn’t start happening until i downloaded enchanted by nature. I tried to play the game without enchanted by nature downloaded and the game still crashed. What could this be and what should I do. Please help!
