Peculiar No GPU Display Situation

[NickHayashi]

This is my build:

 

Motherboard: Gigabyte GA X99 UD3

GPU: MSI Radeon R9 280x 3GB TWIN FROZR

PSU: Corsair AX850 850W 80+Gold

 

CPU: i7 5820K (not overclocked yet)

Cooler: Noctua D15

Ram: 32GB DDR4 Crucial Ballistix Sport

 

Storage:

Sandisk Ultra II 480GB

WD Caviar Blue 1TB

 

The issue I'm having is this:

When I have my graphics card connected and powered, it will stop my computer from displaying/it will not display.

Currently, all I have to test is a VGA-only monitor and a VGA-DVI adapter. I plug my DVI-VGA adapted cable into the DVI port on the card and the monitor, and I get no display.

 

For troubleshooting purposes I have used a very old gpu (zotac gt 220) in place of the 280x to see if it would display (my motherboard does not have onboard video). When using the DVI port on the old gpu, the computer will display, When using the VGA port on the old gpu, the computer will also display. However, if I connect and power both graphics cards in the system at once, NEITHER will display EVEN if I configure the bios to prefer to display to the older card. The 280x will heat up and the fans will spin, so I'm led to believe it isn't completely dead.

 

Other things I have tried:

- swapping the dual 6+2 pin power cable for another one

- moving the GPU to a different PCI slot (the gpu only fits in slot #2 and #3. #4 is a single slot and #1 is blocked by the cooler)

- updating drivers (I downloaded and installed the AMD catalyst driver, but will this even work since I cannot download it while the GPU I am updating is connected?)

- updating BIOS (I'm on the F6 Bios, the newest non-beta BIOS)

 

I'm really at a loss here, guys. I feel like I've tried everything.

RMA, seems like a lemon.
