Unable to play for more than 10-15 minutes

So I’m having an issue that I’ve been trying to self-diagnose for a few hours and I’ve gotten nowhere. After startup I have, with luck, ten to fifteen minutes to play before I CTD. This, along with three complete PC crashes, has made the last day of play rather arduous. I love the content that I CAN access and look forward to this issue being resolved soon. But in the meantime does anyone have any advice to prevent these crashes?

  • Assign more memory to page file,
  • clean fans inside your PC (may it be that CPU or something else are overheating and it crashes whole system)
