This issue has been happening for a few weeks now. Some weeks it won't happen at all and some weeks it'll happen 6 times. It isn't a consistent program or task that makes it happen. It was seeming to happen only during a power surge so I replaced the battery backup that the computer is plugged into and it just shut off an hour ago with no power surge. The computer has worked perfect for 2 years in another office and now that I have moved it to a new office it has this issue. I've been thinking it has been power issues in the building but the battery backup should be there to solve that issue right? Signs point to the PSU I guess but I don't have another one to swap it out with and before I just start replacing stuff I wanted to see if anyone had any ideas.

Thank you,

I think I figured out that the GPU was getting hot and shutting the computer off without warning. I added a side intake fan that blows on the GPU and a top exhaust fan and it hasn't happened since but its only been a couple days.
