PC Reboots While Live Streaming

[blaker26]

I've had my computer for just over a year, I can play games at high performance for hours at a time no problems, however as soon as I try to live stream through StreamLabs OBS I make it anywhere from 10-45 minuets before my screen goes black and a loud buzzing sound plays through my headset. There is no blue screen or acknowledgment of a crash, the fans keep spinning and rgb stays on, then it reboots, the whole process is as if I simply hit "restart". CPU load stays around 60% and reaches a max 75C, GPU load will reach 100% occasionally and maxes at about 80C, RAM maxes at about 85%.
