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.

 

Gaming FPS Drop/Stutter after recent Windows 10 update.

After this new years update, I noticed that my games have been getting frame drops and stuttering. I have a NVIDIA GEforce 1070 and I was able to run games such as CS:GO or League of Legends smoothly before the new year. However, after the recent Windows
10 update, my computer can't handle the games well. For example, League of Legends ran at 144 fps (I capped it there) and constantly ran at 144 fps before the new year. However, after the new year update, my League fails to consistently run 144 fps, drops
down to even 90 sometimes, and there is a lot of frame stuttering that is inhibiting my ability to play the game. Is there anything I can do to fix this?

 

Fps drop feel laggy and stutter.

Using geforce experience, instant fps is fine, my 99% fps drops sometimes and my game stutters. I cannot find any fix, does anyone know how to fix this problem?

I'll reset my pc change os but problem still happening in every game and ideal use ex. Browsing or only move mouse. Mouse arrow still stutter sometime.. what i do please help.

My specs- ryzen 5 3600

Gpu - rtx 2060

Ram- 16 gb

Thank you.
