Solution
You said the system locks up when you download a game not just play it. A slow video card will not cause that, something else has to. For your CPU and power supply, nVidia 750 Ti is a good card.

I have power supply and nvidia graphics card 400w power and geforce gt 720 4GB
So it seem when I do something like download a game a browse the Web my new pc restarts or freezes
 


If it's a clean Windows setup, you need to basically take everything apart and make sure it's seated properly, especially the CPU heatsink that it's installed properly with thermal paste. First time builders tend to forget to use that.

Also what is the brand and model of the power supply? A poor power supply will cause issues with system running.

Why that video card? It's very weak for games. You should have gotten cheaper and less RAM and a faster video card. 16 gig even in a good system is a bit much for a gaming system, in a system with a weak video card it's really over what is needed.
