Pc streaming issues

hello all i have a problem, my brothers pc crashes after x amount of live streaming. he says first his mouse and keyboard turns off than monitor after all that his pc crashes. could it be driver issues or a psu problem? any feed back would be awesome. thanks <3

First figure out what exactly a crash means.

A BSOD(sometimes they need to be enabled)? A power problem? An overheating problem?

Driver issues would most probably manifest as a BSOD. Power/heat as sudden shutdowns.

ahh ok :) thanks for the quick reply :D
