FPS Stuttering issues

[Noxides]

I noticed that my pc is stuttering a whole lot, and i have no idea why. After a windows update it got worse, and i cannot revert back because i had to delete my old windows files to make room on my ssd. UE4 has it worse, like i can barely even work in it. what could be wrong? I also update nvidia drivers and it got even worse, i reverted back to 388.59 and it got a little better. What could be causing this?

PC Specs:

i7-6700k 4.2ghz
1 4 TB HDD
2 1TB HDD
1 120GB SSD
32GB Ram
GTX 1080 FTW

When stuttering look at task manager to see if something is overloaded. What are your cpu and gpu temps? Maybe it’s throttling

Nothing is over heating, and task manager seems fine.
