I've just built a new rig about 2 months ago and recently its been shutting itself off, usually when I'm playing a game. At first I thought it was a nasty bit of malware so I just wiped my HDD and re-installed my operating system and it seemed to work, but then this problem occurred again, after downloading something not so trustworthy so I repeated the whole process of wiping my drive and installing the OS again only this time it didn't solve the problem. Now my computer will shut itself down whenever I try to download the first set of windows updates. I'm fairly certain my PSU is to blame, but I have no way to know for sure and would like a second opinion. Is my PSU failing?
