Wait your running the game on a low end CPU integrated graphics. That is where I would start troubleshooting. Do you have access to any semi modern (new then 4 years) cards? Any friends with an old AMD 560 or Nvidia 960 handy?
If you don't have access to a semi-modern GFX card then you can do as Einobi said, reduce your settings to the absolute lowest and see if you still experience crashes.
My recommendation is to pick up a Nvidia 1650 or AMD 580 both of which can be had for < $160. (Less if you are willing to buy refurbished)
