GPU runs for a moment then shuts down

So when I turn on my first own build PC, all fans start running and everything works fine, but after 1s of GPU running the fans stop and on my ASUS Z170-A motherboard starts to blink a small red light under the ''logo'' ( ''logo'' is on the left side of SATA cables )
There goes power to the GPU, because there is a white led when PSU cable is on it and red when it's not, so it's probably not about the power.

EDIT: I had a fingerprint on the CPU so I used nail polish remover to clean it off, then added a good thermal paste there. So does the nail polish remover have anything to do with it?

Specs:
i5-6600k
Cooler master EVO 212
ASUS GTX 960 Strix 4gb
ASUS Z170-A motherboard
2x 4GB HyperX RAM
WD Blue 1TB
Samsung 850 250GB
Corsais 650W PSU
BitFenix Comrade case
 

If I take the CPU power cable off then GPU works fine, but when CPU powet cable is on it then mu GPU just stops right off.

 
Your motherboard needs a 24pin and a 8 pin, the 8 pin from the PSU will be ether a 4+4 cable or a full 8 pin normally marked ESP. Do not use a 6+2 cable for the motherboard, those are for your video card. Your video card needs to have a 6 pin power cable plugged into it, this can ether be a 6 pin or 6+2 with the +2 just hanging there (it will not be used)
 



This means you are really screwing up your system by shorting it out!

Go to http://www.playtool.com/pages/psuconnectors/connectors.html and make sure you are not connecting a PCIe power to your EPS/ATX or vice versa, you can fry your system and even cause a fire!
 
An Asus GTX 960 4 Gb edition card is a 120w part.

It requires the card to have the six pin 12v Pci-e power connector from your Psu to be connected to the graphics card.

Click on the picture link for your model of motherboard you have bellow.
You must make sure that from the power supply unit of your system to the motherboard.
That the eight pin black in colour power connector on the motherboard.

Is also connected direct from the corsair 650w power supply you have.
That is pictured in the picture link to the left most outer edge of the motherboard often stated as the 12v E-atx power connector or 12v Eps power connector of the motherboard.

Once you connect this and the 12v Pci-e power block from the Psu.
The red light will turn off Method.

And the system will power up right.

Once done you must connect the video cable from the monitor you have to one of the video ports provided on the motherboard it`s self Method.

If you get a bios post or self test information on the monitor screen, press the key it states to enter the bios of the motherboard.

For the default graphics card interface to Initialise first, set the mode option to Pci-e.
Save the changes to the bios before you exit it.

Then take the video cable from the back of your motherboard, and connect it to one of the video display output ports of your GTX 960 Pci-e graphics card.

Where the bios and system post will be displayed on the monitor after you have made the bios changes to Pci-e.

You next step is to enter the bios of your system again.
And set the WD Blue 1Tb hard disk in the boot order of the bios to the second boot device number two.

And the optical dvd drive or usb flash drive to number one in the boot order devices list.
To do this you may have to select a advanced mode setting of the bios setup.

Again save the changes you made in the bios for these steps before you exit the bios setup of the motherboard.

Now just simply place the windows os install, and setup dvd disk in the optical drive of the system.
Or if using a Usb flash drive to install windows os from connect the drive to any usb port of your system build.

And begin the install of windows os to the 1Tb hard disk drive following the windows setup procedure.

 

Nope, I have the PSU cables on their right places. There even is a text that says ''PCI-E'' as example.
 

Yes, I have the PSU cables on the right place. 6+2 pin cable (my GPU only needs 6pin and the 2pin is just hanging without no use) with a text that says ''PCI-E'' on my GPU and 8pin for my CPU power and 24pin for motherboard, then sata cables
 

I have done everything right and the red light is off, there is a white light on the GPU when the PSU cable is on it's place.
Everything works fine, but still my GPU won't run correctly when the CPU has power in it.

 



What does the 8 pin say on it? Is it a straight 8 pin or is it a 4+4 pin cable?
 

8 pin says ''CPU'' on it and it goes perfectly to CPU power socket.
EDIT: and yes, it's just a 8pin, not a 4+4
 

Not sure what ''modular'' means, but this PSU is the VS650 and all the cables are coming inside of it so there is not such a place like ''right spot on the PSU''
This should be an easy computer to build but something is wrong here and I really don't know what.
 
A corsair vs650, hmm wondering if you got a bad unit. The VS and CX are not very good lines form corsair.


Full Modular PSU

Comes with no cables pre-attached. You only attach the ones you need.

It is more expensive, but also gives you more options, allowing you to only install the cables you need and keep airflow and cable management to a maximum. All newer generation HALE PSUs are fully modular.
 

Well, looks like my case doesn't even need standoffs...
I really don't know what to do now, I've tried almost everything.
I'll return all the parts to the store on monday and let's see if anything is broken.
There goes 1000€...
