I just bought a ROG CROSSHAIR X670E HERO, connect all cables and power supply, the start button and the flex key button flash quickly.
The system does not boot.

no q-code.

I unplugged video card changed ram but no change.

A thousand thanks

Hello,

Ensure all power connectors are fully inserted.

If using extensions, remove and try using OEM PSU cables.

Ensure motherboard stand-offs are correctly installed in the chassis.
