CPU AND GPU LOADING 100%

Hi @Carbonic and thank you!

I've read your post and I will provide more details. On screenshot you can see that while I am in game it loads up to 100% and when I tab out it drops down almost to zero. 

Some more info about my system which im working on still:

CPU: i5-8600k

MOTHERBOARD: MSI z370 TOMAHAWK

GPU: MSI GTX 1060 Gaming X 6 Gb

RAM: Crucial Ballistix 8 Gb 2666 Mhz, I am about to buy more soon when I get money

Also, I am using pretty cheap cooler but seems its not a problem. Anyway I am going to buy water cooling system soon.

Processor is working fine, I mean, even on 100% it's very stable and game runs on 100+ fps without any lags.

I really don't understand why it loads that much. It has 6 cores and 6  threads. As I said, mine old i5-2500k without overclocking wasn't loaded more than 80-90% with 4 cores and 4 threads. But it was okay for it since it's really old processor.

Also, when I was installing Windows, I installed MSI Gaming APP and accidently put CPU into gaming mode, I don't know did it change something but after I could not turn it back so I just deleted that app because someone said "If you delete it will turn back into normal mode". Also I checked in BIOS, seems like it is in a normal mode after all. But I think that "Gaming" mode just puts your CPU on a highest GHz it can reach
