Decent specs but stuttering in games with high fps (especially Fortnite)

Hi. This all started a few weeks ago when I was playing Fortnite and I stuttered for a second while in the waiting lobby and whenever I die. It also occurs once in a while when I'm roaming around in the game. I've tried a lot of tips all around the internet but none of them seemed to work. If I go to System Configuration > Services > Hide all Microsoft services > disable all > Apply > OK then restart my system twice, I could play Fortnite like normal only for one time. If I close the app and run it again, the problem will occur.

Specs:
-i5 10300h @2.5GHz (Was Overclocked)
-GTX 1650 (Undervolt core clock with Overclocked memory clock)
-2x8 GB ram ddr4 @ 2667Mhz
-512GB SSD
-Windows 10 Home Version 20H2
-DirectX 12

BTW, I'm using a laptop and not a desktop...
 
Whenever you have issues like that you should always put all the overclocking back to stock speeds then retest from there.

I fixed it by resetting my pc. I think the registry was the issue, but I never made any back up whenever I meddle with it...
