Hello, I upgraded my computer in January and after a month of trying and failing to fix this issue I've decided to ask here for help. The main component of my upgrade was going from an i5 2380p to an i7 6700k. Along with the new processor I bought new, compatible RAM and a new motherboard.

The Issue
So the restarts I'm getting are sudden and without warning. I could be in the lobby after a match in Overwatch and the screen will go black, I'll hear my case fans stop and then the computer will restart with no blue screen or any sort of log that pops up afterwards. This happens in Overwatch, Hearts of Iron 4, and Cities Skylines. Weirdly it doesn't ever happen when playing Battlefield 1, which is the most graphically intensive game I play.

What I've Tried so far
Typing in my symptoms into google led me to a few different discussions on various different boards including this one. So far there has only been one effective fix that I could find. I installed a program called Nvidia Inspector and used it to cap the FPS on all effected games at 60. This completely fixed the issue in Hearts of Iron 4, but does nothing to help in the other games that are restarting. Reading through other discussions with similar symptoms, I realize that this could be a power supply issue, but I just want to try everything I can to fix it before I go buy a new PSU.

Computer Specs
i7 6700k
Cooler Master Hyper t4 cooler
Gigabyte GA-B150M-DS4H motherboard
Corsair Vengeance LPX DDR4-2800 2x4GB
Zotac GTX 960 2GB
Rosewill Green 630W 80+ Power Supply
Windows 10

How can I go about narrowing down and solving this issue? Any help would be appreciated, thank you!
 
Solution
Beside PSU it can be many other things causing it.
Im not an expert but here what i would do:
Have u overclocked your gpu?
Double check all connections, are they all secure?
Check RMB windows>event viewer>windows log>system for errors right after your pc crash.
If you have spare time check your rams with memtest86 (leave this for the end)
Monitor your temperatures using http://www.cpuid.com/softwares/hwmonitor.html during gaming. What temperatures u see?
Did u mess with BIOS?

!!! I cant find motherboard on the internet with DS4H at the end, only DS3H that supports DDR3/DDR3L , to be 100% sure go on gigabyte website find the motherboard and copy the link here.
