I'm not sure if this issue has been addressed, this is the 1st time I've been here.
I have an X 51 desktop.. it is about a year and a half old. I've never had problems with it till just about 2 weeks ago. Now it randomly shuts itself off, no blank screen or anything like that, just turns the power off. When I restart it, it gives me the option for a restart or advanced options. I have noticed that it only cuts off if I am playing a game such as Witcher 3 or World of Warcraft. It dosent do it when using less intense games. I also just moved to windows 10, so not sure if this an issue.
