Graphics card not showing in bios on new board

[JosBlea]

Hi Guys,

I built a pc a few weeks ago with the following components:
i5-7600k
MSI h270 Gaming pro carbon
Zotac GTX 780 Amp! edition
Corsair CX650M
And all was good. Then I decided to sell the CPU and Mobo to my housemate so I could upgrade. Yesterday, I upgraded to:
i7-7700k
MSI Z270 Gaming Pro Carbon
I kept the Graphics card and PSU.

I spent a fair while yesterday taking the old stuff out and assembling the new stuff. When I had finished tinkering, I tried to get it to boot and.. nothing. Long story short, I swapped the two sticks of ram over (ie put them where the other was) and it started behaving itself.

My issue is that my graphics card isn't working - it boots but only with on board graphics.

I've spent a few hours now fiddling with it - ive taken it out and reseated it multiple times, checked the power cables 4 or 5 times, tried booting with it lifted, installed new chipset drivers, rebooted, flashed the Bios and I've had no luck. Previously, in windows device manager it showed me as having an error in a PCI controller, but since installing the new drivers that's gone away.

Going into the board explorer in the BIOS, it shows the pci slot where the graphics card is as being empty. I plan on asking my housemate to put my Graphics card in his PC to check and see if it works there.

If all else fails, I'm going to try putting the graphics card in a different PCI slot (Something I can't currently do as there are hard drives stopping me, meaning I would have to take everything out of the case and breadboard it)

Right, I tested my GPU in my housemate's PC and it worked, so I moved it down into the next slot in my motherboard, and it was fine
Will be calling to return my motherboard tomorrow.

Tried to mark this answer as best so it shows up for anyone in future, but may be that I can't answer my own question, i don't know?
