Hey community,

I started installing my new build a few days ago. All parts are completely new and should I installed them carefully. I'm not new to that, so for now I'd assume, that it's not due to wrong handling.

Build:
Motherboard: Gigabyte x570 Pro Aorus
CPU: Ryzen 7 3700X
Graphics: ASUS GeForce RTX2060 Dual Adv Evo
PSU: be quiet Pure Power Pro 11 550W
Memory: 32GB Black DDR4-3200 DDR4 G-Skill

The Problem:
Motherboard doesn't post or boot, no fans, debug led are dark (A). Only a white led (B) close to the I/O Ports flashes shortly. I don't think it's the PSU, as the led (C) on the RTX is on while on power.

What I've tried:
  • generally I disconnected every unnecessary component to debug, leaving me with: Motherboard, PSU, CPU, CPU Fan (default), Memory (only one of both 16GB parts on the second socket), graphic/video card, and one micro SSD directly attached (D) to the mainboard.
  • remounting CPU, RTX, Memory (checking for damaged pins)
  • disconnecting every cable and reconnecting (on different ports/slots, where possible)
  • clearing CMOS be shortening the CLR_CMOS pins
Is there anything else, I could try before returning the motherboard?
Thanks in advance!
