Question My CPU Usage is too high and causes low FPS in-game

[Mair0n]

Hello,
Yesterdey I got a really serious problem!

I saw that my FPS is way too low in-game(Fortnite for example) and I used MSI Afterburner to monitor CPU Temp and Usage.
So I findout that my CPU Usage is way too high(normal temperature) but not constantly, it just like bunny, 50%>>100% and comes down >> 80% and again 100%.

After that I just opened my case and separated CPU Cooling and the CPU and put them back again(for checking CPU Pins).

Then when I turned pc on it won't boot again and DRAM was solid RED.
Then I just checked my RAMs and findout that two of my RAM Slots were dead.

When pc boot up still same issues.
I checked my CPU with Intel Diagnosing Tool and everything was ok.

I checked everything, I took apart my pc and build it again but nothing changed.

Help me please, is my motherboard died?

Here is my HWMONITOR for Motherboard and CPU:

My specs:
MB: Asus H97-Pro
CPU: Intel core i5 4690
GPU: Asus Strix GTX 1080 A8G
RAM: For now(because of dead slots) 12GB DDR3 1600Mhz

And I know my system isn't balanced!

what do you mean my low fps? if you got like 100 fps that is not low that is pretty good
fortnite is badly optimized with shadows, i got 10 fps on rx 580, 1080ti is 1.3 times better that rx580, guess how much fps it will take?

I'm playing fortnite near 3 years and trust me I know how many fps should I get!
Before yesterday my fps was 74 fix without dropping(my display is 75hz)
but now it's constantly low! NOT dropping
It's around 20-50 fps
Believe me I know I have a serious problem
