PC restarts when Skylake iGPU is used

Made custom W7 iso with NTLite. Taking away my GTX1070 because I want to minimize factors. i5 has integrated GPU anyway. Here I have found out that:
>my PC restarts the moment more than a little 3D (2D too?) graphic acceleration is done via intel HD graphics 530
>like Windows Aero turned on -> restart
>yet the Intel® Processor Diagnostic Tool claims success
>then I found out the GPU core in my Intel has 0 Volts. WHAT?
>went to BIOS, so much settings, only a few has something common with iGPU.
>set CPU C states from auto to disabled: nothing
>set CFG lock to disabled: nothing
>set RC6(Render Standby) to off: voltages of iGPU core went from 0 to 0.7V
>now I am able to successfully install drivers to HD Graphics 530 and set resolution to fullHD.
>now the Intel diagnostic tool fails right at the first GPU test
>voltage of iGPU set from AUTO to Threshold, + maximum value (0.6V)
>now the voltages are actually at 1.7 or more
>Intel diagnostic finish even at fullHD resolution, cores pic related. I can turn Aero on for few minutes until it restarts again.

I have run memtest. No errors.
I have run prime95 for an hour while overclocked to 4.2 GHz, temps never went over 60C (this happens when you buy the best cooler I guess).
I have run Intel Diagnostic multiple times. It fails only with default BIOS settings and when iGPU drivers are installed.
I have tried on fresh W7 and W10 install (with no internet), just the diagnostic tool and driver for iGPU. Same diagnosis.
I have updated BIOS to the latest version (maybe this was bad idea?).
I have cleared CMOS (because there were no "reset to factory settings").
My PSU voltages (reported in BIOS and HWmonitor) are withing 5% error margin.
>What can I do to determine what is wrong?
Is my PSU too weak / broken 8-pin 12v ATX?
Is my motherboard faulty in any mysterious way (I looked at every conductor, nothing seems bad, but I am no expert either?)
Is my Intel Sky-lake CPU broken? Only the iGPU part? The part where it determines how much power should go in?
Is my default BIOS settings too retarded? Or is Asus selling mobo's with crap default settings unable to run supported hardware with supported OS?
Am I retarded? (I have to admit my logical reasoning behind buying this mobo was: WOW! WHITE color! BUY IT!)

>Spec:
mobo: ASUS SABERTOOTH Z170 S (chipset Intel Z170)
CPU : Intel Core i5-6600K (Skylake)
RAM : Crucial Ballistix Sport LT (2x16GB) DDR4 2400
PSU : Seasonic S12II-620 (620W)

So what do I do now?
Anything I have missed? No I don't have spare PSU, CPU or mobo.

I have read on shady places that people have 1st life time experiences with faulty CPU's ever and that it is Skylake. Am I another victim or did I miss something?

Please help.

Install gentoo

I would seriously just try to boot off of a linux live cd or something and see if the problem occurs there too. If it does then it is gonna be your hardware that is having this problem for sure.

No need to do this.

>made custom w7 iso
stopped reading right there.

And I know for a damn fact Skylake and Intel hd530 is buggy as fuuuuck on Linux.

same thing happens to my setup.
not sure if it is my used motherboard that i bought from ebay or the used intel i5-2400 that i took from a dell workstation.
>computer turns on.
>computer is fine.
>watch a video or something that stresses the gpu
>crash
>install graphics card.
>everything is fine.

You do know that windows 7 doesn't include Skylake support right?

>I have a GTX 1070 but it won't boot with iGPU

???

Even if you explained, the novel you posted isn't worth reading through for the answer.

Sounds like your CPU is overheating. It'll cause a system failsafe reboot.

Did you put too much thermal paste on the CPU lid? Skylake CPUs run hot.

You do know that means jack shit, right?

They run cooler than Devil's Canyon
