	Well at least you are getting A2. I think Dr Debug is not showing errors specifically, but rather status of boot secuence. If Dr Debug shows A2, it means boot secuence got stuck there. A0 - IDE initialization is started A1 - IDE Reset A2 - IDE Detect A3 - IDE Enable I would unplug all attached drives (including usb headers on motherboard), clear CMOS (follow instructions provided in this forum) and try booting. Also check that cables and memory sticks are firmly connected.

	C0 is refers to boot device selection. C0 - OEM BDS initialization codes I understood you tried booting with only one stick of RAM? Have you tried reseating CPU? Also when installing CPU cooler, don't overtighten it. Try booting with oy CPU, one stick of RAM and GPU installed. To be sure reconnect all motherboard cables also. If it still won't boot I think RMA the motherboard. I replaced both my motherboard and PSU. Replaced Taichi x299 for Taichi x299 XE. PSU was probably the problem. I was confident that it can't be PSU (Seasonic Prime 860W) as it was new and previously working fine. Replaced motherboard and still couldn't boot. After replaced PSU too and this seemed to solve it.
