Hey this just started to happen a few days ago out of no where i had this pc for a couple months now no problems. When i play any game for like 5 mins the Screen goes black and the sound stays like 2 more seconds after the screen goes out then stops. The numpad key turns off but i cant unstuck it but my mouse and Astro Mixamp stays lit, then i have to Hard reset my pc. I reinstalled windows completely and updated the bios and the problem still persist, so it has to be something maybe The power supply? I cleaned my pc out as well had a little dust didnt help and all my temperatures while gaming are great. So my question is how can i know for sure what is wrong with my pc so i can know which part to buy? btw here are my specs
i5 6400 cpu
R9 390 8gb
8gb Ram
600 Evga Power Supply
Asus h110-Plus motherboard
