Hello everyone,

I just received all the components to build my dream PC.
CPU: Ryzen 2700x
Mobo: Taichi X470
RAM: 2*8GB Vegeance CL16 3000Mhz
GPU: EVGA GTX 1070 FTW
PSU: Coolermaster 650W Bronze
Storage: Samsung 960 EVO Pro 256GB
Cooler: Noctua NH D14

Yesterday received the Taichi and started assembling the PC, when finished I switched on the PSU and the motherboard started blinking blue light and does not do anything.

I have already tried:

Removed all peripherals -> no success
Removed the RAM leaving only one module in A2 -> no success
Tried CLCMOS button -> no success
Removed the mobo from my case on its box and kept only 24 pin + 8 pin + GPU 2*8pin -> still nothing
While on the box re mounted the CPU -> still nothing
During night removed the battery and tried earlier today -> nothing

Next step I will follow is:
Remove the Noctua brackets to put its original brackets just to esnure no shortage caused by the brackets.

All the components apart from the mobo were already tried in another PC and they work properly so the problem has something to do with the mobo.

Please if you have any ideas help me out. Have in mind the mobo I purchased on a used but working condition.

Best Regards,
Alex Bedini
