Frequent crashes on ASUS i7 with Geforce960M

Since I have FF XI running on my new laptop it crashes every 1-2 hours, consistently.

Observations so far:

* It only crashes when FF XI is launched with Windower

* It crashes even if I run Windower with all add-ons/plugins disabled.

* it's not related to lag, certain weather or zones, memory usage, heat or cpu intensity;  it even crashes when my character is idle in mog house

And yeah, it's starting to drive me crazy.

Laptop specs: Asus with Intel i7, NVIDIA 960M, 8MB ram, Win10

HELP!!! pls
