New build, hoping to put the computer together for Star Citizen. Thought I was ready to rock, but then OH NO, PC won't power on for more than 10 seconds at a time.

I've looked at the troubleshooting guide, clear CMOS, breadboard, disconnect restart cable etc, check pins under CPU, still no dice.

Frustrated, at this point happy to know if I've bricked something so I can replace.

Processor - i5-6600k
MOBO - Gigabyte GA-Z170-HD3
CPU fan - Coolmax EVO 212
RAM - Kingston Hyper X 2x4gb
Graphics card - Gigabyte GTX 1060
HDD - Western Digital Blue 1TB
SSD - Samsung 850 EVO series 250gb
PSU - EVGA 650w Gold
Case - Fractal Define R5
No optical drive (yet) EDIT - nicked an optical drive from an old PC just in case its needed for the solution

Symptoms - all fans turn on although GTX 1060 fans turn off almost immediately. Can hear HDD start up. No signs of life from a monitor using HDMI or DVI cables

Thanks for reading, please fix my deep pain :(

Solution
Update - my computer works, I'm typing on it right now.

I had an IT enthusiast look at the set up and he couldn't find a fault, which just goes to show how small a mistake can be.

Ultimately I took the rig to a professional for a full diagnostic. Result - DDR4 Ram appeared to the eye to be installed correctly, but required a bit more force to correctly insert it. Failing to install the Ram is a rookie mistake - but be aware the level of force required in the end was fairly high.

Hi. Tested with 24 pin power cable by itself and then again with both 24 and 8 pin

I tried to systematically do all testing with GTX 1060 graphics card and then without. Breadboarding I tested with only RAM (1x RAM and then 2x RAM in the dual channels 1+3), CPU, CPU fan.

CPU fan appears clear of other components. I'll remove the fan in a couple days anyway when I have an experienced IT dude helping me, will post results here. For gaming reasons though, I will need some kind of CPU fan
