Computer freezes and crashes while playing computer games

So, I've recently upgrade my computer added more rams, and bought a new GPU, and while playing computer games my computer starts to lag and then the screen lags on 1 frame and then I have to restart it.

Try removing one brand of ram. Mix matching sticks is not a good idea. Also what PSU are you using?

I did that, and my PSU is Codegen 500W

That would be my prime suspect. No name PSU's like that are not very good. It probably doesn't have the needed amperage to run such a graphics card. I would replace it with a quality unit, like a Seasonic 520w/620w, or a Corsair CX550m/650m.
