Windows 10: Sound Cuts tied with FPS drops during gameplay

Hi, When I play games despite the intensity of power requirements for example Call of Duty or Minecraft. I would start to get FPS drops and game audio cut outs every 1 second as well as my microphone with voice channels like Discord or TeamSpeak.I have double checked to see if Antivirus is running a scan, closed any additional programs and opened task manager to see if another back ground services are spiking and drawing power from the CPU & GPU but all seem normal.Regards,Jeremy

without any fps problem , but now after 5min smoth gameplay its going to freez and drop fps every 3second .you thing the best solution now is installing 1703 ? or install 1803 ? or maybe its hardware 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.

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