I again reinstalled windows and reset bios to check if drivers or bios settings was the issue, and yes now the stuttering is gone. I might need to check on what drivers caused it
Thanks for all the help :) !!
My pc started stuttering/lagging whenever I opened hwinfo64 and found that it was this specific sensor which was causing the issue. I had to disable monitoring of the whole cpu section to remove the stuttering.
Please can someone help me on this?
I am worried if this is any kind of hardware...
