Pc stuttering at low temps/no overclocking

[ss313ulc1]

My computer for the past month has been stuttering. I don't know what's the issue since I replaced my GPU and reformatted my computer. It also occurs when I'm just browsing the web in chrome, not only games.

Specs:
Msi Z370 M5
16 GB Ram 3200mhz G Skill TridentZ
Gtx 1070 sc evga
I7-8700k
Corsair hydro h100i
Corsair Rmx 750w PSU
Samsung SSD Evo 250gb 2x
