WU Drivers or Manufacturer drivers?

[GGWP1337]

Hello, since I formatted my PC it started after i play Dota 2, it will after 1 game sometimes 30 minutes in the game, start to drop FPS, let me tell what I have done.
Updated Bios <- Didn't solve my issue P 2.10 - P 2.40
Fresh install, where i download and install the drivers from ASRocks webpage (Forgot to say Windows 10 shouldn't install drivers thorugh updates)
A new fresh install, where I let WU install my drivers, though not my GPU, i updated that, and kept doing that, still not solved the issue
I tried using sfc /scannow <- No issues
used the Windows memory diagnostic <- Didn't find any errors on my ram
a user told me to disable fast start, it solved my taskbar not running after cold boot, thanks!
now i have this issue in Dota 2 i get massive framedrops from 100 - 67 suddenly when a lot is happening, but if i load up Dead by Daylight after it will run fine, maybe drop 1 frame once a while, but it's far not noticeable.
I am not sure if I should make another reinstall with no internet, and then download the drivers, another user said i could do something else

I am using an ASRock z87 EXTREME 6 Motherboard, with i5 4670K and GTX 1070, other games doesn't seem to have issues but Dota 2 have, and it's even eating my CPU sometimes it takes over 70% CPU in Task Manager.
I also ran heavens benchmark, gave me good results

I could also run Prime95 for 5 minutes, no issues.
But I am confused what to do?
Should i use ASRocks website, or can i use the links above with Intel?
Please help me out here!
Oh yeah

I ALWAYS manufactures drivers if available , since they are updated on a more regular basis.

 

[GGWP1337]

So you would recommend a complete reinstall, and disable windows drivers from installing, right?

 

[Dark Lord of Tech]

I always install the go to manufactures site and install:

Audio
Chipset drivers
Lan
USB if available or needed...usually windows gets this one right.

Get GPU drivers from Nvidia or AMD depending in the card you are running.

Okay, so I have to make sure and disable Windows in the driver section, and install without internet, right?

 

[Dark Lord of Tech]

No need , you can update to the latest drivers after windows install.​

Windows finds a lot of the drivers , so don't disable , you can find the latest after OS install.

Even after a format with no internet and also i disabled the Windows update for drivers, (Sorry didn't read till now) while process, i can't even have 9 chrome tabs, one is a twitch.tv stream open, unless my FPS in Dota 2 can fall drastic 105-maybe 70 ofc it's not much but i can feel the hard drop. but it becomes more stable if i close the stream, problem is i really like watching some streams while playing games as well, but if i can't even do that what is seriously wrong with my PC? 
This never happend with my old old i7 2600k, it's like my motherboard is broken, or the CPU? can someone please help me what is wrong with my PC? :S
