No display output & VGA light on brand new desktop!

[captainhillman]

Booting up an order I just received, unfortunately I'm getting a solid VGA light on the motherboard and no display output (cannot even access BIOS). I'm plugged into two Dell P2414H monitors via Display Port. These monitors have no HDMI ports (but I guess I could temporarily plug the machine into the TV's HDMI if really needed). I've tried various combinations of ports, and turning the monitors on before/as/after the PC is booting, no luck so far.

Specs are below, thanks in advance!

Can you try connecting one of the monitors to the Displayport socket on the motherboard (at the top of the back panel), rather than the GPU, to quickly test if it it's a total system issue or just the 7900XT.

The GPU or its power supply may have come slightly dislodged during transport, so we can check that once we know the rest of the machine is working.

BTW, you may find the boot time is considerably longer than you're used to, as AM4 and DDR5 memory training takes some time to settle down (it will eventually get down to c.30s, but can be as long at 120s initially).

No luck on that either, exactly the same result (VGA light, no output).

I would try reseating the RAM along with the GPU and check all power cables. It's more than likely something has dislodged in transit.

Last thing you want to have to do is send it back.

Just as a triple check, I would try it on the TV via HDMI.
