Alienware 15 R3 Gpu usage drops to 0% and game freezes for 1s, happens every 10-20 sec

[System97]

Hi everyone,

A few month ago i encountered this annoying problem that after around 5 minutes in game, the screen freezes every 10-20 seconds for about 1 sec. I noticed that first in hunt: showdown and pubg i have done a lot of research since this happened first but nothing seems to work. Now im having the same problem with the game Apex Legends. I tried setting the graphics to potato-mode (everything-off and ultra low) but that didnt work, and the temperature is also around 75° so no heat problem. 

Im playing on a Laptop:
Alienware 15-R3 64bit
intel core i7-6700HQ 2.60GHz
GTX 1070 8Gb
Windows 10

Thanks for any help!

This is wat my Gpu usage looks like
