Hello, I just built my new pc, Ryzen 7 2700x, ASUS DUAL RTX 2060,GIGABYTE B450 Aorus Elite, G-Skill Aegis 16GB 3000MHz, 600w EVGA and then i went to play fortnite and after 15 minutes the graphics card shut down and ran full speed while the pc still on and i couldnt power the pc off unless i turn the power off so after that i stress tested my gpu for an hour and it was totally fine and i tested my cpu and it went fine too so i went into the game and check temps while in a game and it was at 60-65C and i dont think it was the psu because i put my hand on it and it wast hot at all it was like 37C. Thanks
