MSI Trident X display issues

[sgoaty]

I've got an MSI Trident X 9th gen system 9700k, 32gb RAM and it did have a 2080 but I've sold that and was planning putting something a little older in it until GPU prices settle down a bit the only trouble is I can't get anything else to output a display in it.

I've tried a titan X Maxwell and a GTX 780 both give a VGA error although I did manage one successful boot on the titan X somehow. When refitted the original 2080 it worked fine it also works perfectly with the onboard graphics.

This system has some sort of daughter board like a PCI-E riser but with other cable connections on it. Could it be some compatibility issues with that?

The bios is also quite old but it seems to take a different bios to the stand alone motherboard one z370i gaming pro carbon AC so I'm reluctant to update it incase I brick it.

Just wondered if anyone can help?
Thanks

Do you have a picture of this other board? I'm not familiar with Trident X systems, but some risers have sockets on them for power etc. It's possible that the riser is defective or isn't drawing the right power for some reason.

Could it be defective if it's still worked with the 2080?

I've uploaded some photos of it here
