Hi,
I am suffering from completely random FPS drops in the game, sometimes i can play a game for a few hours and everything will be fine but suddenly something happens and fps begin to jump. What i mean is that it goes from 150 to 50 stays at 50 for a minute or so then goes back to normal, and stops lagging and this just keep happening every few mins

My Laptop specs are:
Lenovo Y50-70
GTX 860M
Intel core i7-4710HQ
8GB RAM
Im running win8.1

I think i have tried everything, nvidia share is off, drivers are up to date, power setting are on max performance as well. Any ideas what could be wrong?

But why sometimes i can play whole day without lag spikes, and next day it will happen right after i launched the game? I mean i would understand if it would be consistent but now its random
