Windows 10: FPS stuttering

I Have a GTX 1050TI, i5-7400, 8 GB RAM, SSD PC since 2017 and i recently got a problem where FPS started to stutter when i play video games like LoL or Valorant, and i wish i just could know what is the problem to fix it, is it windows problem ? Virus ? Hardware problem ? i wish if someone could help to identify the problem

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.

MSI Afterburner 2

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

 

Fps drops and stutters

So I used this debloater tool to debloat my windows 11 and soon I used the restore point I made but it gives me lower fps rhan before I used the debloater and alot of stutters

 

FPS drops below 10 every couple of minutes

Very interesting. Our default suggestion list for fighting stutter becomes more interesting.
