Windows 10: Fps drops for 10-20 seconds and then going back to normal and happening again after 2-4 mins

Hello i have a Hp pavillion gaming laptop which has amd ryzen 5600h3.30ghz, 8 gigs of ram7.34 usable for some reason and gtx 1650 in it. it was working fine for 3 years but suddenly 3-4 days ago it started getting fps drops in almost all games. i used to play csgo 2 at 110-120 fps in mid setting after a few minutes it drops to 9-10 fps for a few seconds and goes back to normal. this happens with almost every game, i have tried a lot of methods like resetting the pc without deleting files, is there any solution to this

:)

 

fps drops to 5-10 every 2 minutes

so i have a nice enough config to play games at atleast 90-120 fps on medium setting i even get that fps but after like just 2-3 minutes fps drops to 5-10 for like 10 seconds and then back to normal but this keeps happening every 2 minutes its obviously unbearable

 

Fps drops

When i play games on my laptop i get huge fps drops like i am playing at 165 fps it would go down to like 70 fps then go back to normal and happens every few seconds. My specs are rtx 3060 i7 12700h and 16gb

 

Sudden FPS drop/Stutter

Since 2 days ago, I just turned on my Computer, and it starting having issues while I was playing Witcher 3 (starts with decent fpsm and then very low fps, dropping to 35, then 20, and stopping at 12 or so, in a matter of seconds, in a matter of 1min of starting the game), also stuttering without any high demanding programs, randomly. I was playing at 45-60 fps, without any stutters or sudden fps drop. Have tried other games the issue persists. Even setup everything to low settings.
I have ran several tests with several tools, all seems normal, no sudden memory spikes, or temperature raising out of the ordinary, nothing that would indicate such an fps drop or stuttering.

MSI Afterburner

I also did the reset option on Windows10, completly cleaned out all my personal info from the windows partition.
So at this point, I am not sure if it is a software issue or a hardware issue.
Any suggestions are greatly appreciated.

Edit: I kept doing some tests to find out the issue. And this happened before and I was able to replicate it. Same thing happened as before, till I set it up to fullscreen, Alt+Tab from the game and then back to the game, FPS went up to 50 again, stable and good, dropped after a couple of seconds. After a bit it went to 2-5 fps, and I had to shutdown the game, because even the sound was getting messed up.

In this image those ups and downs in the GPU usage are when the fps dropped really hard and the sound got messed up.
