PC not posting after reboot

[Joaquin RP]

I built a friend a PC and it worked perfectly when I booted it into Windows at my house, bur now that he has it, it refuses to even POST. I have discarded faulty port, cable, PSU, PSU connections, RAM and CPU.
Any idea why it is not posting?

Already did. No results. Even after changing slot.
I updated the topic with the specs

I know, he used th PSU money in the GPU. Still like a 100W of headroom though (give or take).

I have not tried that. I will now. I´ll let you know if something happens.

I can't see any information in the motherboard manual but are there any Qcodes or Debug LEDs?

To my knowledge the only troubleshooting LED is the Mem_LED

If that's the case I would also just start reseating everything. It's entirely possible something got jostled loose in transit.

It might help.
