Windows 10: FPS stutters in every game

I have rebooted my whole System/Windows completely and also completely formatted all my hard drives with [diskpart > clean all]. Now I noticed that I have random fps stutters in games. Such problems like that I never had before, everything ran super smooth. Does anyone have an idea what it could be? I tested witcher 3 and fortnite and it runs much worse than before. : Specs:Rx 6600 8gbRyzen 5 560016gb RAM 32002tb M.2 SSDWindows 11 22h2

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.

 

[MOVED]FPS stutter in some games

Since I upgraded to windows 10,some games have huge fps stutters,they run at normal FPS but once in a while I get a huge stutter that lasts up to 2 seconds,and then everything goes back to normal only to stuttera again 30 seconds to 1 minute later

All my drivers are up to date and I have tried lots (and I mean lots) of "solutions",nothing worked so far.

My hardware is:

Cpu: Intel Core i7 920

Motherboard: Asus P6T SE

GPU: NVIDIA GeForce GTX 960

RAM: 6GB

 

High end build, stuttering in every game

Hello, this is my build:

• i5-6600k
• ASUS MAXIMUS RANGER VIII
• MSI GTX 1060 6G
• Samsung SSD 850 evo 250gb
• WD Caviar Blue 1TB
• G.Skill Ripjaws V 3200 DDR4 (XMP profile)
• Dual monitor: Zowie XL2411 144hz + BenQ GW2260 60Hz

I get stuttering in the following titles:

• Rocket League: every time a new player join a match the game freeze, also when V-Sync is on I get random lag from 144 to 130 and then the game continue to run smoothly.
• GTA V: random stuttering Online and fps drops, V-Sync on.
• PUBG: random stuttering, V-Sync off.
• Rust: stuttering when loading chunks with fps drops.
• Ark: as Rust.
• Total War Warhammer: random stuttering in the strategic map, V-Sync on.

What I've done till now:

• Tried every graphic settings.
• All kind of Windows 10 optimizations like Performance mode, Xbox game mode off, disabled unnecessary services and tasks, no antivirus (Windows Defender on only).
• Hard drive defragmentation.
• Nvidia control panel optimizations for every game like Thread optimization, tried several v-sync modes, etc.
• All drivers are updated.
• No pending Windows updates.
• Temps are fine, GPU and CPU never go above 65C.
• Shadowplay overlay off.
• Playing with one monitor at once.
• Moved games from HDD to SSD.
• Tried different version of GPU drivers.
• Disabled the page on the HDD and fixed its size on the SSD with the reccommended value.
• Memtest for both RAM stick at once (8 pass each no errors).

What I've not tried yet is to reinstall the OS... benchmarks and performance in game are ok and in line with every other user... do you have any suggestions? Could it be network related? How can I analyze the stuttering?

PS: I'm testing with Latencymon and doing some screenshot of gpu and cpu usage
