troubleshooting Booting trouble

[Levaru]

So I recently started an ITX build so I can have something more portable than my regular pc. It uses the exact same parts (literaly taken from my desktop and put into the new build) except for the cooler, psu, mobo, and a m.2 ssd.

After putting everything together and turning it on I cannot get a display signal from it. Opening the case I made note of what LEDs are on and it turns out none of them are. I tried turning it off and back on and saw that the boot LED never turns on or flashes at all. The only two LEDs that turn on during post are the CPU and DRAM, which stays on longer then what I'm used to.

I've tried changing ram slots, (but with the DRAM LED turning off I doubt that is the issue) clearing the RTC, changing boot devices to my desktop ssd(the m.2 works fine in my desktop both for storage and booting) yet none of these could get the boot LED to turn on.

It's a but weird asking why my pc won't have an error LED but it's not working anyways so I think that's the problem. I'm currently thinking the mobo is broken and an RMA would be my awnser but is there anything else that I can try before doing a RMA?

I tried taking out the battery and doing RTC but the POSTwent to the DRAM, stalled for a bit then restarted itself. After the restart it continued with no change, No boot LED or display signal.
