X299e-ITX Nothing happening on power up.

Hello,

I purchased this motherboard quite a few years ago but it has been in the box brand new until I finally acquired all the parts I needed to build the computer with it.

CPU: i9 7980XE 18 core
RAM: Vengeance Corsair DDR4 3200 4x16gb for 64gb
GPU: Nvidia 3070

PSU: Corsair RM850
Case: NZXT Manta

I have probably built about 20 computers in my life from parts so I have completed builds many times before.

This is the first time a powerup didn't post at least a Bios.

I booted down and reseated everything I could think of.

RAM one per slot try to boot each time.
Checked the M.2 expansion card... etc.

I am not sure what to do here.

There is no light on the motherboard letting me know the power is on except the fact that the ethernet port, when the cat6 cable is plugged in, does flash yellow off and on.

Since I didn't see anything sent to the screen or hear any beeps I swapped video cards with my working main rig to make sure it wasn't the graphics card.

I also tried the hold the CMOS reset button down as I found another post saying the same thing happened to another customer in 2020.

Sure enough the graphics cards worked in my older computer just fine and sent a signal to the screen.

Is there a way to RMA this motherboard?

It is the first one I have ever experienced not having at least a logo or Bios post to the screen.

Thanks for any info or suggestions you have.

Also, if there is no RMA option cause of how old the board is... I am still interested in it being repaired if you have that as a service.
