Windows 10: My pc gets fps drops that drop to 3 fps and my audio sounds like static, this only happens...

When I start to play games my pc its fine for maybe 40 - 60 minutes, then I start to get random fps drops that drop to like 3 fps then my audio sounds like static, this only last for a few seconds but it starts to do it every 4 minutes or so.

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.

 

Fps drops

So hey,

For example im running a game everything good

After some time randomly my fps drop down to 95 fps and stutter a bit while under normal circumstances then mever drop under 180 so we speak about a huge drop.

After this drop happens i proceed running task manager and the issue is fixed just the second i task manager.

Its weird and i dont really know what happens
