Hi Adam
I have a similar problem with an ASUS G750JX, power laptop but render crashes all the time. Between Microsoft, Asus and Nvidia, the consent diagnoses so far is that the card is not getting enough power when its rendering (the explanation is much longer), but what I stumbled on is when I unplug my laptop power it renders fine but takes 2-3 times longer to render. I am still trying to get it resolved and will update you if I get a long term solution.
