2080-TI FPS Drops and Stuttering

[Dullay]

So recently, I was facing the issue of restarting my PC in order to get stable FPS. When I use to turn on my PC and play Witcher 3, I would get 70 Avg and after restarting the PC it would go back to 134 FPS Avg. I play on a 240Hz 1080P Monitor which is G-Sync compatible, this week n now I tried restarting but no change, I get stutters on every game almost and worst of all I get 120FPS locked on CS:GO. I tried it on other games thinking it might be something else but still the same averaging 65 on all games. These are the following steps I tried from the internet:

- Using DDU to uninstall my drivers in safe mode and reinstall with a clean install.

- Changing GameDVR in registry to 0 and other one I did i forgot the name.

- I reinstalled the Window and no effect.

- I turned off Real-Protection in Security on Windows 10

- Checked my clocks while playing games, it always stays stable at a good 1985MHz with a 55-60C on avg with CPU avg 57-60 avg depending on the game. That's the maximum i have gone with the temps.

- Cleaned all of my PC from the inside and took out the dust with the blower.

- Checked voltages and checked my memory speed for my RAM in the BIOs which is at 3200Mhz

 

I am deeply confused with what's happening I know that there is nothing seems to be wrong with the hardware but its the internal software wise issue, it would be deeply and heart fully appreciated if you guys could sort out this issue for me. The specs for my PC will be given below.
