Hello i have been having stutter issues on many different games mostly call of duty titles but i dont understand why i built this pc only a few weeks ago.
my pc is more than enough to run most games i play at high setting and still over 100 fps but its always the same stutter for a few seconds works fine then my gpu usage drops to 0 and i get a bad stutter then it goes back to normal and my cpu is never above 60% usage. sometimes it will go awhile without another stutter sometimes its every other second and then some games work flawless i could have forgot to install some drivers but i dont think so i got the amd cpu drivers and the nvidia drivers but nothing else since i heard windows 10 is better at downloading the rest automatically please any help would be great.

specs
gtx 1060 strix oc edition
ryzen 5 2600
8 gb ddr4 3200mhz
