Ok so I have a X99 Micro 2 rig I built for one of my brothers. It has a Xeon E5-1620v3 at stock clocks, 16gb of the Gskill RGB series 3000mhz ram but not clocked to that IIRC, a GTX690, and is running Win 10 pro 64bit. It's having random shut down issues and flat out refuses to ever play AC Black Flag, but that's minor compared to the plethora of random shut downs during games and other random times. No real blue screen as most of the time a game will hang and the system restarts or it just blacks out and restarts.
This has been a pretty consistent issue with this machine. We did lose a Samsung Evo M.2 to it a few months back but Samsung came through with their warranty and since then it has not been reinstalled yet so that rules the SSD out for being the issue. We also swapped GTX690's out for one I had that was pulled in working condition and issues still persist after driver updates and the like.
Looking for some ideas on where to start next, reinstall of windows has been ok'ed by my brother but this has been done before when the SSD crashed. I am suspecting a possible conflict with the Xeon and RAM but would like to try other possible solutions before putting money into it for an i7. Thanks.
