game locking and closing

my computer has a configuration of a Core i5 4440 - 12gb memory - GTX 760 2gb 256bits - SSD 240gb (with more than 100gb free) and even so, the game just closes, no matter if I'm on safezone or making some game map. In the Harvest league there was no such problem, my game ran at the maximum setting at 80 FPS, even today playing at the lowest setting, I go from 110 FPS to 10 or 3, sometimes 1, and the game hangs and closes, even though it is stopped without any effect on the screen.

This has occurred with several players.

Any solution?
