New PC wont show boot screen on tv(In need of help asap if possible)

[Inperatrix]

Hello, I just finished building my new pc and I have it connected via HDMI as well as tried a dvi-hdmi connector to boot it up on my tv ( no pc monitor atm). The tv will not show the boot screen or anything at all since it is a brand new computer. Everything within the computer is on and running so the power should be fine. I also attempted to use the hdmi on the mobo slot as well as GPU 1 and GPU 2 and it still will not show. Would anyone be able to assist me with this it would be much appreciated.

MOBO: Formula 7
GPU 2x MSI 970 Gaming Golden Edition
CPU: i7 4790k
Thank you.

If its an ASUS and it supports USB BIOS flashback update the BIOS first. Then see if it works

How do I go about doing this as this is the first boot? and thanks for the quick response.

Also I just attempted to boot it with only 1x of the RAM sticks and now my mobo reads A2 on its display do you happen to know what that means?

Read the manual on how to use USB BIOS flashback. I dont know what that error means. I t should be in the manual

Well if it isnt turning on update the BIOS first

Still nothing appearing on screen.

It doesnt HAVE to be on to use USB BIOS flashback. READ THE MANUAL

I did the BIOS flackback to the latest version and my tv is still not being recolonized.

If theres more than 1 stick of ram make sure you install them in the right slots. So youve connected the CPU fan, ATx 12v and obviously the 24 pin?

If the mobo has onboard video remove the 2 cards see if it works

I put it down to 1 stick of ram a while ago and it is in the correct slot. And the required cables are in as the computer does start up. I will attempt to remove the 2x GPU's I guess.
