Greetings @ahatten05
Two options
a) the pwoer adapter failed or is not fully plugged in
b) some wires are not fully seated
Do this for me
a) Unplug usb cable, as it carries 5V and could power up JUST the motherboard
b) Look at your power adapter, without USB does it show solid green LED?
if not thats the problem. Try reseating it in the mains socket
If it shows green LED, press power for 5 seconds
If this fails could you post images replicating the below guide please
