Question MSI B450I GP has EZ Debug VGA LED

Oct 30, 2018
Hello, I have a problem with my Motherboard and my new case.
I have the MSI B450I Gaming Plus AC and just got myself a Phanteks Enthoo Evolv ITX.
I tested the mobo before in my old big atx case (it fitted) and it worked like it should. Then my new case arrived and I installed it. After I finished, I started the PC and there was no video signal at my monitor, but all of my case fans, rgb stuff and the gpu fans were working fine, just the VGA LED was lighting. So I checked if the gpu is connected correctly and if all the other things were connected correctly, they were. Then I got the mobo outside of the case, connected it, reset the CMOS and turned it on, it bootet onto the desktop. So I got the mobo inside of the case again, but it didnt worked. It just showed the same LED again.

I dont know what to do anymore, any thoughts? :/
