I assemble my own pc but no matter what I do it fails to post.
My setup includes a 9800x3d, asus tuf gaming b850 plus with wifi mmo, corsair rm850x psu, g skill 32gb ddr5 at 6000mhz ram, and an 2070 super gpu from an old machine.
I attempted bios flashing using the latest update; the faster blinking indicates a successful update.
When I power on the system, all RGB indicators (aoi cpu fan, case fan, motherboard RGB, ram RGB) are active and fans are running.
The motherboard debug LEDs show no errors, but I still can't access the bios.
I removed the battery to reset the bios, used only one ram, unplugged the gpu, and tried connecting via the motherboard dp/hdmi port.
Even after sending back the cpu for replacement, it still won’t boot.

Welcome to the forums, newcomer! I own a 9800x3d, asus tuf gaming b850 plus wifi mobo, corsair rm850x psu, g skill 32gb ddr5 6000mhz ram, and a 2070 super gpu from an old PC. Please share pictures of your CPU socket. Do you have a link for your RAM setup? Are you using an iGPU with your processor and getting display output from the motherboard? How are you keeping the processor cool?

Ram shared his issue with no display on the motherboard. He also mentioned using an Arctic Liquid Freezer III Pro 360 A-RGB CPU cooler.
