New PC will not POST! No video signal

[SLADEstroke]

I have recently just built my new PC, though when I power it on only the LED's and fans seem to be doing anything as my monitor can never pick up a signal (have tried both HDMI and DVI) from my graphics card.
I do not believe that the problem lies with my graphics card as I tried using my old one from my current PC in place of it which I know for a fact is in working order, but nothing. Have tried using different cables, reset CMOS, switching RAM slots, reseating the CPU... I have also tried troubleshooting with EVERY step in this guide http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems but still nothing!
I do notice that one of the Case power button LED's flicker, which I have seen may be something to do with the mobo shorting?? It is my first time solo building but I am pretty sure that I have seated the mobo correctly with standoffs as well as screws and do not see any loose metal objects on the board (usually culprits for shorting).
Any ideas would be really appreciated!
Thanks!

My build
i7 6800k

MSI x99a SLI Plus
Gigabyte GeForce GTX 1080 Xtreme Gaming Premium 8gb
Corsair Vengeance LPX 2x8gb 3200MHz

Try removing the graphics card, storage drives, all cables but the 24, 8 pin, CPU fan and power button ones, leaving single RAM module and testing again. If still no go, try posting here a picture of the motherboard.

Thanks for the reply,
just gave one RAM module a go but with no luck.
Here are some pictures though, tell me if you need more

Card, RAM and other cables are still in.

Apologies, hopefully this is better, 24 pin is really stuck in there so don't really want to pull too hard to get it out otherwise there could be some damage.

No problem. In both sets of photos, the 8 pin power cable is not connected to the motherboard, or am I wrong? If not, try connecting it, start the board and see if the CPU fans do spin.

Oops, took that one out accidentally for the photos. But no luck even still. Same problem seems to be that I just cannot get a video signal. Power seems to be running through the important parts, but for whatever reason it refuses to give a video signal.

Try posting a picture of the board as it is now.

Began bread-boarding today, this is how it looks as of now

Ran into the same problems with the board out of the case. Tried a single RAM module, once again the CPU fans and LED's were working but no video signal. Tried both RAM modules, and same again. Tried both HDMI and DVI to no avail.

What are the 4 digits after B in the board's serial number (B1xxx)?

No single 4 digits after B, though I've just put a picture up with the serial label for you

The board needs a BIOS update for supporting the 6800k: https://www.msi.com/Motherboard/support/X99A-SLI-PLUS.html#support_support
I'm not sure with that board if you can update the BIOS without a supported CPU.
Try contacting the retailer or MSI and see if they can update it through RMA.

Will have to try and contact MSI, thanks for all your help
