I just assembled my new pc components outside the case. I have an X570, 3600x cpu, and a rx5700xt. I also have an m.2 sad and a SATA hard drive I stalled. When I start my system up all that comes up is a message “Reboot and Select proper Boot device or insert boot media in selected boot device and press a key.” What do I do to resolve this and get to the bios.

there should be a prompt to get in the bios before hand or the cpu might not be supported on the motherboard, AMD do boot kits where they send out [censored] cpu's for free to update the moba for the new ryzens as they cant be detected by some mobos

But it’s also a brand new motherboard with the brand new chipset for the new and processors. There would be no reason for an update.

are u sure theres no prompt for the bios before it says about the boot device? try spamming F2 or F12 constantly after turning it off and on

Nothing to do with BIOS updates --- the CPU is obviously already compatible with the BIOS and POST is successful, otherwise you wouldn't get that boot device message.

The BIOS/UEFI setup utility does not normally appear automatically, you have to press the specific key which is usually shown on the splash screen eg "Press DEL for setup". (Mine says "Press F2 for setup").

If you don't press the required key, the PC will simply proceed to the boot stage, which is what is happening in your case.
