Asus Rog Maximus XI Hero A2 code and black screen

[Spitfine]

Hello everyone! 

Yesterday I change my pc to a new case, the Helios and also change the psu to a Thor 850w . After that I assembled all, I wasn't able to start the pc! everything turns on, passed on the internal check but on Q-Code gives me A2 with a kind orange led turn on, the last one. 

I tried many things that already saw here. Start without any IDE connect, start only with the nvme that have OS. Start with no memory or with just. Change the GPU 4060 Ti back to a 1070 Ti. Take out the MOBO battery during 5 minutes. I think tried a couple more things don't recall of them now. The only I didn't try was updating the Bios! So my question here is, does anyone have more suggestion? Before I go with the last resort?

Hello @Jiaszzz_ROG 

Thanks for replying.  I tried some of those options. When I wrote my post I didn't remember everything that had tried before. But anyway, just to say that I finally was able to put everything to work. The weird thing was the black seemed to be related to the cable HDMI. I changed the cable to DisplayPort and started to get image back. Was stuck on BIOS post. Did some changes and voilá, everything is back to normal again! In 25 years of assembling computers this is my first time that I gotten something like this. 
Thanks again for the help.
