Hello. I am currently using an alienware desktop from 2013 and it is having issues. The one I am here to ask about is when ever I run CS:Go once I am in game my computer will shut off as if someone has unplugged it. To get it to turn on again I have to switch outlets. I have used multiple outlets throughout my home and none of them seem to resolve the issue. Do any of you know what is going on with my computer?
