New pc experiencing fps drops and other graphical issues.

Hello, i built a new pc 2 months ago and its been giving me some issues since i got it.

My main issue is it's dropping frames in games, mainly destiny 2, I'm running it on custom settings mostly high, some medium but i get random fps drops. i also have issues recording gameplay with software such as shadowplay and OBS.

My specs are: cpu ryzen 5 2600x (stock cooler) gpu gtx1060 6gb 8gb ram ddr4 2400mhz single channel ROG strix b450-f motherboard windows 10 home

At first i thought it was a cooling issue, as the cpu's stock cooler is kinda bad, however i ruled it out because i installed msi afterburner and temps were normal.

I also thought it might be the thermal compound because i had a bit of a hard time installing the cpu cooler, took a couple of tries and wasnt sure if the compound got ruined.

at the moment i suspect it might be a ram issue, kinda like a bottle neck since im not running dual channel, because the OS is a bit laggy sometimes too.

i've also been having issues with sony vegas crashing whenever i try to add new media.
