FPS Stutter lag

[buuddyy]

Hello to whom may read this,

 

I have been attempting to troubleshoot a FPS Stutter lag issue with my PC. I will be play a game for instance league of legends and after about an hour of playing my FPS will go from 230 down past 60 and lag for about 2 seconds. Then it shoots back up and does this cycle for the rest of the time I am on my pc. It also does it if I am watching a youtube video or pretty much everything on my pc.

 

I have been monitoring my CPU and GPU temps. CPU is a Ryzen 5 2600x. My CPU temps do not look like they are the issue.  My GPU is a gtx 1070. That doesn't go over 50c. I did a memory diagnostics and got no errors back. Here is a speccy of my build. http://speccy.piriform.com/results/hunQ6b8hfoWJv8VeLBVbGTe

 

I have tried reinstalling Windows 10 2 times on two different SSD's. One being brand new. While I am playing I have open task manager, but nothing is shooting up to 100% when the stutter occurs. I have made sure drivers were up to date and my BIOS is up to date. I am at a loss. Do I need a new CPU, motherboard, psu? Thanks for any help.
