Windows 10: BSOD a couple times, now constant fps stuttering

I received a few BSOD a few days ago after updating my graphics drivers. I thought it was simply an issue with me messing with sound settings while installing my new headset steelseries headset while playing a video so the audio was getting messed with a lot, however, I do not believe that to be the issue overall.Since then I've noticed severe fps stuttering and drops I can't seem to get over 50-80fps on any game when a few days ago I was getting over 100. FPS also does not seem to be stable and jumping a lot between 50-80 at any given moment.I've reinstalled the graphics driver twice as o

Constant stuttering and fps drops after fresh installation

I had a long running problem where whenever playing a certain game for longer than an hour 2, id blue screen with various error messages including but not limited to: kernel_mode_heap_corruption and Kernel_security_check_failure. I reinstalled windows
and updated my drivers accordingly and now can't play anything without constant stuttering and fps drops. I've researched this problem as much as i can and have done all things listed on the forums including checking for corrupted files, rolling back/uninstalling
and reinstalling my audio/touchpad/gpu drivers, disabling that dumb xbox dvr thing, and the problem persists. I had no such problem prior to my re-installation so i believe it has to do with the fresh install of windows 10. This problem is absurdly annoying
and my hardware is more than capable of running any game at a playable fps.

 

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 below 10 every couple of minutes

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