well, it happens on pretty much every game I play (gta v, 2k15, tomb raider, arkham knight), also same thing happens when I wake up pc from sleep)
I have my gpu overclocked to +225mhz clock, so I tryied to lower oc, but even at +100mhz crashes happens. But the most interesting thing is that without drivers crashes but clock speed doest drop to 540mhz.
My build is 4770k, 16gb ram, 512ssd, h80igt cooler, maximus gene vii mobo and reference 980.
