So, my computer crashes during the summer time under heavy load. It'll stutter with audio and video some times, and crash at others. When it crashes, the the IO will stay stuck if it was pegged, the monitor will freeze, and my RGB keyboard will freeze. It doesn't write to the event viewer. I've got 3 3000rpm noctua fans for airflow, a cooler master closed loop cpu cooler for my fx-9590, and a 980ti. My CPU stays around 50-60c however, under load my gpu gets to about 75c max. I've got an EVGA SuperNOVA 750 watt B2 80+ PSU with the PC part picker rated at about ~580 watts. Any insights as to why I get these crashes? I can get whatever info you need to help troubleshoot. Thanks!
