Newly Built PC starts up for not more then 15 seconds, then restarts infinitely

[Kevin_198]

Before you tell me "Oh check the CPU, check the GPU, replug cables, make sure every cable is plugged in properly, try ram slots individually" etc. I already tried all of the above, the CPU is fine no pins are broken, GPU is brand new 1080 and the led's are working on startup, all cables all in correctly (I checked the negative and positive place as well) and when I tried other ram slots other then the recommended it makes my pc start up and in half a second shutdown and loops. Send help? My case didn't come with a speaker cable so I can't troubleshoot very much, any suggestions? All of my parts are brand new from trusted companies like NCIX and CanadaComputers. Here are my specs
-EVGA GTX 1080 FTW gaming
-Intel i7 6800k
-Gigabyte GA-X99P-SLI LGA2011-3 motherboard
-Samsung 850 Evo 500GB SSD
-3TB 7200rpm Barracuda Hard Drive
-Corsair 750D Airflow Edition Full Tower ATX case
- EVGA 750W G2 PSU
- Corsair H100i 280mm liquid cooling
- No optical drive
- Zowie 2411Z monitor
- 2x8GB G.skill NT series ram
I'd also like to add that my monitor doesn't even goto bios and it displays "no signal" even though my cables are properly connected.

The board might need a BIOS update for supporting that CPU, but "and when I tried other ram slots other then the recommended it makes my pc start up and in half a second shutdown and loops. " points to a bent pins issue, although you said you checked them.

If you've checked everything else, and you're still getting a boot loop, it comes down to a couple things:

1.) you've got faulty ram.

2.) you've got a faulty motherboard

3.) both 1 and 2.

Or you have a dead power supply, but it's a EVGA supernova, so I kinda doubt it. Or your CPU cooler was mounted with the LGA115X standoffs instead of the 2011 standoffs so the CPU is overheating on boot. Or you've shorted against a rogue motherboard standoff. I highly suspect a DOA motherboard and/or RAM though.
