Random half a second stutters when doing anything. i5 6600k

[superman2233]

Hi, last month i built my new gaming pc, and now im encountering an error where the pc stutters/freezes for less than half a second and does like a stuck cd drive sound during that time (no, i dont have a cd drive).
Last 3 times that that sttuter happens i have opened the task manager and the cpu was 100%.
Also im using "open hardware monitor" to monitor the temps of the cpu and gpu and after stutters the max percentages of cpu usage in the program show 100%.

So i started thinking it was the cpu.
The cpu temps are right, as it normally stays at 45° celcius when not gaming and around 50° when gaming thanks to the hyper 212 evo cooler.

Now the motherboard: its an asus Z170-A and it doesnt have the lastest bios update. If i type "systeminfo" in cmd it shows that it has the 1902 bios version.
If i go to the asus driver-webpage and to the "CPU support" tab and look for my cpu it shows that the lastest bios (i guess is the bios for that cpu model, i dont really know, never flashed a bios before) its the 2202. (full link below).

For the GPU: i have a EVGA GTX 1070 acx 3.0 (yes, the model that caught on fire) with the lastest bios (anti-fire bios lol). Only problem i had with it apart from running games at 80° celcius before the bios and one full pc freeze (i guess it was for the temps, and also before the bios) that made me unplug the pc to turn it off.

And about the coolers, im running with only 1 cooler (back exaust) in the case, but surprisingly no high temps.

For the windows part: Im running windows 10 64-bit home edition, and i did a clean install one month ago when i built the pc. The OS is installed in the SSD.

So... i dont really have an idea why this random sttuters that happen every hour or so happen.
Last thing i wanna do is to update the motherboard bios, cause i dont want to have a random power outage that ruins my motherboard in the process.

Like i said in the beggining everything is new, and has less than a month of usage.

What exactly makes the "stuck cd drive" noise? That's significant.

I dont really know how to describe that noise lol.

 

[Ecky]

Yes, but what is it coming from?

 

[superman2233]

Yes, but what is it coming from?

Oh sorry, i read "how is that noise" or something like that. The noise comes from the pc audio (headphones).

My first suspicion is the hard drive. Do you have a sufficiently large flash drive or spare hard drive to install Windows on and test?

I guess the SSD works perfectly, cause i had it in my old pc, the same day i built this pc, and never had a problem with it before.

What clockspeed are you running your 6600k at?

 

[superman2233]

What clockspeed are you running your 6600k at?

Actually, i dont really know, the "windows computer" specs show 3.5ghz, but the open hardware monitor shows 3.9ghz.

And, no, i didnt modify the clock speeds in the bios.

What does bios say the clock speed at?

Does your motherboard have any easy overlock switches that might be enabled?

 

[superman2233]

No, there are no overclock switches enabled, it was the cpu "turbo mode". But the stuttering problem is still happening, now with a random full freeze when doing anything. It happens like twice in a week and mostly when i leave the pc on and leave, because when i come back and log in nothing that i left open is there, like if the pc reseted after a freeze.
I dont really have a clue of what is happening here

 

[superman2233]

Actually when i built the pc i didnt even configure the BIOS, maybe i am missing something there.
