I have checked the cables i have checked the ram there is no error display or lights or anything. But when i plug in my keyboard and mouse the rgbs dont light up on them so i believe they dont work. Idk what to do.

my specs:

Mobo: Asus prime b450 plus

Gpu: Msi gaming trio x 3060 ti

cpu: Amd ryzen 7 5800x3d

Perhaps there is a PC speaker to be attached, as that would give error codes. described here:

Have you updated the BIOS?  The Ryzen 5000 will only work in that motherboard with BIOS version 3211 or later.  That is a very late BIOS version so the board most likely shipped with an earlier version of the BIOS.

Yeah the reason these older boards are so cheap now is because you need a supported CPU to fix this problem.  Although given how far back it goes, a really old supported CPU shouldn't cost much.

Indeed.  AMD would actually send you a Ryzen 1200 for free so you could update the BIOS for these boards to support a 5000 series CPU, as long as you sendt the CPU back to them obviously.  I dont know if they still do this.

The fun part is that some of the boards dropped support of the old chips in a bios version you need to install in order to update to the version that is needed to run the latest processors, so you could wind up in a situation where you need 3 different CPUs (if you already have like an A series chip installed for example)..
