Before sending in;
have you tried furmark? Or Intel XTU's monitoring software?
Check your HDD, GPU and CPU temps. Your Z5 should have outstanding cooling abilities. When I meant outstanding, it shouldn't even reach 90c at all for CPU and GPU under full fan (the laptop's own fan) blowing. If something is, probably it needs servicing.
Once that's done, look again at the Intel XTU and let it run as you play overwatch. See how the temps kick in when the turboboost is activated (its activated automatically).
Sometimes that's the one that causes all the headache.
have you upgraded your windows from a previous windows recently? (not that its a good thing, but its worth looking into it as one of the causes)
