Need assistance mounting an XFX Radeon R9 290

I just purchased a bunch of new computer parts to build my first computer, with the assistance of several friends who are computer savvy. Right now, I have an Asrock B75M-DGS R2.0 motherboard, an XFX Radeon R9 290 video card, and a 600W PSU, among other things.
The hard drive I was building with was not previously wiped (my bad), so when trying to install Windows 8.1 after mounting and connecting everything, I had to just connect the USB with bootable Windows and boot to that. The display I was using was a TV via HDMI. This was successful. Happy with that, and once Windows finished, I shut down the computer in Windows, unplugged my peripherals and power cable, and moved the computer to its new home.
Upon trying to reconnect everything, and using a new power cord that a friend brought (it was longer than the previous one used, but same shape), I was unable to get a display via either HDMI or VGA. I believe what fixed that problem (for whatever reason) was putting my computer back on the previously used power cord (although I may be wrong).
My next step was to start downloading drivers for my motherboard and video card, as I don't have a CD drive. I did motherboard first, all directly from the website. All fine. Tried to first download the auto detect option for driver installation from AMD, no success. Didn't recognize my system, or something. Next, just manually searched for the driver in the website, was instructed to download the latest version of Catalyst. This download (and following install) seemed to go off without a hitch, except that nothing really seemed to be installed.
Booted up a game, and the FPS wasn't nearly what I was expecting. The computer didn't even sound like it was pushing itself, but my FPS was low. My first thought was whether the computer was defaulting to the onboard graphics, instead of my card. Upon searching in device manager, there was no evidence of the card. Booting up into BIOS showed no card in the slot. Turned everything off, remounted the card (in the same PCIE1), and turned on into BIOS again. No luck.
Help?
 


The 8pin and 6pin are both connected to the power supply. The cable being used is an 8pin to two 6+2pins.
 
Have you tried hooking your TV to the on-board graphics? Typically when I build a system I install the OS with the minimum amount of components possible. Then I'll add the GPU and any other cards. It helps with troubleshooting any problems. Also check to make sure that the GPU is fully seated in the PCI slot. That card is a beast.
 


My current situation is that I can connect to a VGA display (VGA port is on the motherboard) and boot Windows successfully. My video card's fans are running, but BIOS does not show anything actually connected in the slot it is seated in.
 


Correct. No evidence the card is actually connected to the motherboard, other than the fact that I did it myself, several times. Nothing listed in device manager, and nothing listed in the PCIE1 slot in BIOS.
I can't switch between PCI and PCIE1 also, due to the shape of the card itself. I also currently do not have any other computers to attempt to mount the card in.
