Sudden freeze ingame?

[MrXuha]

Hi everyone, 
Recently upgraded my motherboard, psu and ram from receiving it as Christmas gifts and now when gaming on my PC I find that I sometimes freeze in game for a few seconds?
This didn't happen at all in my old build and I'm wondering how to fix it? 

Old->New:
CPU: i3 8100 -> same (upgrading to i5 soon)                                                                                          
GPU: EVGA GeForce GTX 980 -> Same                                                            
MOBO: Gigabyte H310M -> Gigabyte Aorus Gaming 3                                                                    
RAM: 1x8gb Kingston HyperX Fury CL16 2666MHz -> 2x8gb Kingston HyperX Fury CL16 2666mhz @ 2400MHz
PSU: Segotep 500W 80+ Bronze -> Corsair RM550W 80+ Gold
