Rog Strix b760-i - pc suddenly stopped working, no Qled

[QhrisT]

Hey,

A few days ago, I left my pc on and went shopping.

When I came back, pc was off and upon pressing the start button, nothing happened (except for the power button led lighting up). I tried unplugging it and hard restarting it and nothing worked.

I started taking out all unnecessary hardware to see if I can make it at least boot, but nothing worked.

As a final test I bought a new PSU thinking that it might be the problem but still nothing changed.

If I try starting it with only 24pin and 8pin plugged it + front panel , CPU and 1 stick of ram, it still doesn't work.

Upon reading more on the internet, I realized that while debugging I haven't seen the Q-leds light up once.

Any ideas?

PS: I also unplugged the CMOS battery for about 10 minutes

Hello, @QhrisT 

May I ask if it is possible that the PC will occasionally experience power interruptions and recover?
When encountering boot issues, are the fans on the PC running?
Based on your description, we recommend performing a bare-board test with minimal components:
Set up the motherboard in an insulated environment with only the CPU, integrated graphics for video output, a single RAM stick in the DIMM_A slot, and the PSU before checking if it can boot into the BIOS.
Please refer to the ROG STRIX B760-I GAMING WIFI manual to ensure all hardware is installed correctly.
If it still cannot boot, please consider sending the motherboard for further inspection.

Thank you.
