The most common things to cause crashes are , overheating caused by fans pulling in dust , you can get cans of air called air dusters from maplins , DONT turn pc on and DONT turn air can sideways or the propellant will squirt out.
The other thing that can cause crashes is having all of a games settings too high.
Start the game with every effect on the lowest possible setting and increase the individual effects gradually to see if you can pin point the culprit. Contrary to what some players say , you cant always see a visual difference when you knock down some settings slightly , if this suggestion works just except the fact that you cant run everything on maximum.
I have a gtx 1080 that can handle anything but their will be some players who do have a card as good as your 1070 so just tweak the settings .
NOTE ... don't use the gforce experience program it is rubbish it sets a game up how IT thinks you want it.
uninstall it if you use it and remove the entry from start up menu .
download g card updates manually and at install choose custom and untick the gforce experience or you will end up with it again .
hope you found my long posting useful.
