Hi all,

Running into some issues that I suspect are related to a dead board, but I wanted to see if there's anyone with some words of wisdom first!

So here's what's going on:
In a nutshell, it's exactly the same symptoms as not pressing the power button. The board's rainbow LED junk is glowing away happily, peripherals have power. No fans, no nothing.

Some system specs:
  • ASUS ROG STRIX X670E-F
  • Ryzen 9 7900X3D
  • Corsair Vengence 6200Mhz (2x 16GB)
  • WD Black NVMe SSD (1TB)

What I've tried:
  • Different memory configurations
  • Re-seating CPU
  • Re-seating GPU
  • No NVMe SSD installed
  • My old board and CPU, which wokred, confirming the PSU works fine
  • Quadruple checking the panel headers and trying to jump the PWR_SWITCH header with a screwdriver, neither did anything.
  • No GPU connected.
  • Updating the BIOS via a USB drive and the flash button, which appeared to work. Drive was active, green LED flashing. Stopped after maybe 15 minutes.

Any thoughts? Just RMA the board I suppose?

I'm really hoping I'm missing something stupidly simple, that would be great! :)
