Problems with i5 7600k + Gtx 1070

[Jblase]

So I built my first pc last week coming from a Gtx 760 i5 4430 to a now Gtx 1070, i5 7600k, ASUS Strix Z270E gaming MOBO and am having some serious CPU usage problems at the moment. The first two nights this beast felt amazing, crisp and clean on every game, then two nights ago I randomly noticed some lag in Player unknown BG and my CPU usage was like 95-99% and was all from my the game causing my pc to lag. Rainbow 6 felt great at first but like listed above also started high CPU usage and was lagging me at times. Would really like some help, I'm desperate. I've done minimal searches since last night but found two resdit posts with the same specs and no fix as of today. I'm at work until 6pm and will most likely on be answering around lunch time EST. I'm really thinking about selling the CPU and going with an i7 7700k if I can't find a fix

Is it really the game wich Bombs up that CPU usage or is it an other Program?
Taskmanager --> Rightclick on your game "Change to Process"
or in windows 10 something like "Go to Details"

Then look at the CPU Usage...

So far when I go into the task manager while playing Rainbow Six Siege, Miscreated, Playerunknowns Battleground, I've been above 90% if not 100% and I can feel it in game which is the problem, I don't want to feel it. It was crystal clear the first two days of playing and im 99% positive I didn't download anything, or mess with BIOS ECT, only thing I can think of was switching my fan headers, but idk if that would make my CPU usage go up?

And yes, it's only the game taking up the CPU usage.

Hmm... so many things... could you have accidentally underclocked the CPU?
For example with the Asus AI Suite
Please again the same process as before....

Open the Game --> Taskmanager --> this time go to "Performance" --> Check the Clockspeed which stands by "Speed"

Is it somewhere around 3.8 Ghz or higher?

Sorry I have been out of town and recently just got back. Completely forgot I had posted something here. Yes it's usually around 4.02HZ in game, but it's still the same, 90-100 CPU % just on Rainbowsix itself, no other opened/in use application

I'm wondering If maybe I installed the wrong motherboard drivers, (which were installed before) I noticed the problem, or maybe the cpu usage was the same the whole time, and only when I noticed it, it kicked in as "im noticing bad performance".
