Question about Gigabyte Z790 AORUS ELITE AX

The board had to be returned, the bios was so fragile that the computer always crashed. I have never experienced this before. With the Asus Prime, everything worked without problems.

I have exactly the same problem, the light goes from ram briefly to cpu and then back to ram and after 8 sec it repeats itself again.
I have already done almost everything, including updating the bios, can you help me?

Solution found... I did the Bios upgrade incorrectly. Very important everything must be removed upgrade. Only the mainboard without cpu or anything else must be on it...

According to the manufacturer with the FG Bios update is compatible and tested, see supported CPU List

Hello, your motherboard supports 12th and 13th generation processors. Your processor that you bought is a 14th generation processor, maybe that's the problem. I hope I've been able to help you.
