Hello,
I have just assembled all the components of a new build and the PC does not power up. When I press the power button, all I see is a small rush of power (lasting only <0.5 secs) and I see the case fan and CPU fan spinning for that time too. Then nothing.
I have checked, & rechecked the onboard headers power connecters are correctly connected and have reversed 2 pin power button connector, but that does not seem to make a difference.
I have also tried to disconnect my GPU, but that does not seem to make any difference.

System
Mobo: ASRock Z97E-ITC/ac
CPU: i5 4690K
Case: EVGA Hadron Air
RAM: Kingston HyperX 8 GB 2400 MHz CL11 DDR3 (2 x 4GB) - Intel XMP
GPU: Asus Nvidia GeForce GTX 760 DirectCU II OC 2GB GDDR5
SSD: Samsung 840 EVO 250GB 2.5 inch Basic SATA Solid State Drive

Can anyone help, or point me to how diagnose what is failing?

Thanks

Your motherboard requires bios level 1.30 to support a i5-4690K
That was released on 6/3/2014.
If you bought old stock it might not have that bios.
Even then, I think it should power up without the latest bios.

Take all your parts out of the case to eliminate a case short as part of the issue.
Use only the integrated graphics and one stick of ram in the proper slot.
Power on by momentarily touching the two PWR pins on the motherboard with a screwdriver.

Geofelt - thanks for the really quick answer. I will try that.
Does it matter which of the 2 slots I put the RAM in?
Where are the two PWR pins on my motherboard, or do you mean remove the power button connectors and touch those pins with a screwdriver? Is is safe?!!

Usually, but not always, it does not matter which slot only one ram stick goes. I might imagine the closest to the cpu.
My manual for the asrock z97e-ITX is limited and does not say.
If no joy, try the other stick and in the other slots too.
The idea is to see if possibly a ram stick is bad or even if a ram slot is bad.

The two pwr pins are where you connected your front panel power switch to. It is a momentary touch switch. By disconnecting the other front panel leads you are eliminating the problems that a wrong connection might cause.
The front panel block is hard to interpret. Look carefully . I have make the mistake of connecting the front led leads to the reset leads causing strange results.
Yes, a screwdriver is safe.

Hi Geofelt,

I have done all of that. The mobo is laying on the wrapper it came in. I put RAM in one slot and then the other and touched the pins, as you described and all I get is a micro pulse of power and then nothing. I must be touching the right pins as I get some some power, at least.

The ASRock mobo was bought in mid June from Amazon. Everything is newly acquired.

I am really getting upset as I've spent a lot of money and now cannot figure what is wrong.

The ssd is the only one attached to the motherboard? Not found in the bios that way? Attached to sata port 0?

See if formatting the ssd on a different pc will help.

Finally managed it.
Formatting the SD on another drive did not seem to to work.
I installed windows 8.1 Pro onto an old spare HDD and then used Samsung's Data migration tool to clone this onto the SSD and then reformatted the HDD.
