Aurora R10, power button blinking lights 2 then 1

Question

My Aurora R10 (Ryzen 7 3700X) does not boot and the power button flashes 2 then 1. The manual says this is motherboard related. I changed the motherboard with a new one, and still same issue. Does anyone have any ideas? I reset the CMOS, removed the memory and inserted one, removed even the storage but no luck. The machine is almost 3 years and out of warranty. Has anyone had this issue?

Thanks,

Oneel

This is what the flashes mean:

NUMBER OF POWER LED FLASHES	PROBLEM DESCRIPTION
1	System board: BIOS and ROM failure
2	No memory or RAM detected, system board, PSU
3	System board or chipset error
4	Memory or RAM failure
5	CMOS battery failure
6	Video card or chip failure
7	CPU failure
2,1	System board failure
2,2	No memory or RAM detected, system board, PSU
2,3	System board, memory or processor failure
3,6	BIOS recovery image not found
3,7	BIOS recovery image found but invalid

Often the easiest fix is to replace the coin cell battery: Coin cell battery guide

If that makes no difference, try the PSU test button to make sure the PSU is working properly: BIST Test

@Vanadiel​ Yes, the 2,1 indicates System Board. I bought a new Motherboard and installed it, with the same 2,1 lights. I suspect the issue is not the board.

Replace the $2 CMOS battery with a brand new one. Make sure your graphics card is fully seated and locked in the slot.

@Masejkl​   you should start your own thread and tell your specific circumstances, like what led up to your PC suddenly not working.
