Any ideas? I'm puzzled, as I've tried two other GPUs with same result.

Ryzen 2000 series cpu? if so you'll have to update the bios with an earlier processor.

Would be happy with any solution, but it's a Ryzen 7 1700, which I assume is okay?

Lights on the GPU are on, fans spinning. Board passes CPU and Dram checks ok. System fans working.

Reduced to 1 stick of ram, in different slots.
Tried the GPUs in the other PCIe slot.
No HD/SSDs connected.
Checked monitor and cables.
Checked all connections.

Stupid question, you've plugged the monitor into the card, not the motherboard backplate, yes? (Everyone's done it wrong at least once in their life xD)

Extra power cables plugged into the GPU?

 

[WGiro]

Yep, and yes [I admit to plugging the monitor into the motherboard, but only out of desperation!]

Did think at first I'd need to update the BIOS for the GPU, but having tried two much older GPUs (one which draws power only from the board) and CMOSing it each time, I'm at a loss.

Assembling the bare minimum out of the case is about all I can think to try. Perhaps it really is a case/seating issue.

 

[WGiro]

Assembling it out of the case got it to work. Must be the case seating! Thanks both.

Glad it worked for you bud

Any chance you forgot the spacers and shorted the board? I did that once and didn't spot it until I'd taken the whole thing out to reassemble from scratch xD

Yeah, good to hear it's working.

I had a problem like that about 15 years ago. Turned out I'd screwed in one too many risers on the motherboard tray. Took me forever to figure out what was wrong.
