CPU Spikes and PC Lag

Hello there everyone, I am writing here in hope of getting some help finding fixing my PC.

My Problem :
- PC Is getting random lag spikes ca. every 10 seconds that last up to 0.5 second each.
- My CPU usage will spike when this happens. Please check these pictures as an example. (https://goo.gl/BEJ7qL, and https://goo.gl/FxXsV9 ).
- This happens when i'm browsing the internet, watching a youtube video, or a livestream, even as I'm writing this text, I am getting lag spikes, and also when playing game.

My PC Specs -
- Windows 10 Home. Build 16299.371. Version 1709.
- Nvidia GeForce GTX 1060 3GB, Driver version 397.31.
- ASUS Prime Z270-K Motherboard.
- Intel Core i5-7600 CPU @ 3.50 GHz

Does anyone have any solutions that might fix the problem ? Or is it even my CPU there's something wrong with, or is it my hard drives that are corrupt ?

Hey Masterchiefxx17,

I used to have "Driver Genius" to update my drivers, so i thought that all my drivers were up to date, but after making this post i installed "Driver Booster 5", and it updated 10 drivers that were from 2017, I haven't used it so much afterwards because it was late, and right now it's early morning, but I will keep on testing and see if i still get lags. Until now it seems fine tho.

So my PC is running normally without any lag spikes in Videos, Games, and everything UNTIL I open up World of Warcraft, then the lag spikes return.

Would anyone have a clue about what causes this ?
