Question FPS DROPS!!!!

[dinner]

So i build almost a new pc.
GPU : GTX 1070 8GB STRIX
CPU : i5-9400F
PSU - Deepcool 550W
RAM'S : HyperX Fury DDR4 2666Mhz 16GB 2x8gb
Motherboard : mot-asus prime h310m-a r2.0
Windows 10.

So I Upgraded my old pc with new parts.
I don't know whats happening with this pc but i got stutters or idk how to call them I play mostly VALORANT I Got aswell A 144Hz monitor Connected to displayport
FPS Is capped at 144 but when i play or see enemy or someone uses abilities i got fps drop from 144 to 130~120 its unplayable.. When i uncap i got almost 300FPS 250~300 but then aswell it isn't smooth and lags. i dunno why. XMP IS ENABLED IN BIOS
Anyone got any tips how to fix?e
