Gigabyte x370 motherboard does not recognize the Ryzen 2700x processor. I would have updated the bios, but the card does not initialize.
If you don't have the minimum BIOS Version installed to run the Ryzen 2700X, it will not boot into BIOS. You would need to install and update the BIOS first if you don't have the correct BIOS Version installed. Some of the newer Motherboard's you can update the BIOS using a USB Flash drive in a special USB Port on the Motherboard without booting up.
Since you didn't mention your computer specs, as an EXAMPLE ONLY, found this Gigabyte X370 Motherboard: GA-AX370-Gaming 5 (rev. 1.0) | Motherboard - GIGABYTE U.S.A.
For the Ryzen 2700X it needs to have minimum BIOS Version F20 installed for the motherboard to recognize the CPU and boot up.

The latest BIOS version for this motheboard is version F25:
Thanks for the answer.
I downloaded the latest BIOS, the F25, but I can not upgrade because the motherboard does not boot.
I saw that some Gigabyte models update directly via USB, without processor and without memory, through a white USB port, but this model does not.
I'll try to find an older processor to upgrade.
Gigabyte has several X370 motherboards. YOU NEED TO MAKE SURE YOU HAVE THE RIGHT MAKE AND MODEL AND VERSION MOTHERBOARD BIOS otherwise you will ruin your motherboard if you install the wrong BIOS from a different model.
Mine was just an EXAMPLE since you didn't mention the exact Make & Model of your motherboard. IF the one I posted is the same Make & Model and version of the motherboard you have now then you can use F25 otherwise go to Gigabyte Support and download the latest for your exact Motherboard.
