Putting the R9 380 in the other slot gets no response. In Slot 1 it made the fans on the card spin, in slot 2 the fans aren't spinning.
Ok so the 380 does not put out a signal in either slot? But you know that the card works as you have tried it in another computer. It could be that your motherboard requires a BIOS update to be able to use the newer card as I know some of the 900 series Nvidia cards require updates on the socket 1155 to work. Check what BIOS version you are on and then check to see if there is an update. From recent experience this is most likely.
I take it you have tried to use the card on its own?
May I ask why you have 2 cards in the one machine? Is it for additional screens or folding etc? No reason other than curious
😀
Regarding flashing the BIOS, the newest BIOS version is recommended for chipsets with the IvyBridge 22nm architecture. Should I upgrade to this version? The older BIOS updates don't do anything on my PC, primarily the 1.I version.
EDIT: Nevermind, after managing to use the correct BIOS update my mobo decided to freeze as it was booting after the update, resulting in the death of my beloved P67A-G45 (B3). May you rest in peace.
Thank you for attempting to help me, really, I appriciate it!

I'll now good look for a replacement, hopefully one that will be compatible with my new GPU.
