good day , I hope you will enough time to see this and respond me.Thanks in advance. So I recently bought new PC:i5 750 2.8ghz,8gb,nvidia geforce 750ti, whenever i play game no matter what game it is (warzone,fortine,csgo) pc restarts after running the game for 15 mins , and the games are going just fine fps is amazing and i ran stress tests on cpu and gpu and pc didnt shut down plus I checked temperatures while gaming and they are normal, I did memmory diagnostic tool , i even reinstalled whole windows and the issue is still there on every single game i play except Minecraft and League Of Legends . Do you have any idea whats wrong
