Hi, i have windows 8.1 64, asus z97m plus, i5 4590, and sapphire r9 290, i can play Dragon Age Inquisition and other demanding games at max without any problem, no overheat, and the power supply runs fine even when everything is working at max, i have left aida64 system stability for about an hour and didn't have a problem, but then some very specific places, my pc just shuts down, there are 3 right now, one at the end of chapter 1 cinematic of Evil Within and when i reach the first bonfire of Lordran on Dark Souls 1, and randomly playing LOL, in the case of Evil Within and Dark Souls is always on the same exact spot, maybe is when the games do something that make me crash but i wonder how to avoid it, i use afterburner with +20% power and manual fan control, also use the osd of rivatuner.
