My pc turns black screen after gaming for a bit and wont shut off or restart unless i pull the plug or flip the switch on the psu. My build is a b350 f gaming, ryzen 5 2600, gtx 1070 armor, corsair vengeance 3000mhz, and a 600w smart therlmaltake psu. No oc everything stock settings except fan speeds and it’s really cold so definitely cant be overheating
