No Signal From GTX 1050 TI, But The Computer Boots Up and the Fans Spin.

So, I'm really at the end of my rope here. I bought a new card today and despite my best efforts I can't get it to display anything. I plugged the monitor in properly with both DVI to VGA(active) and HDMI adapter/cables, I made sure to set the BIOS to PCIe display, I have more than enough juice from the PSU, I uninstalled the AMD drivers with DDU before installing the NVIDIA drivers, I tested it with HDMI to my TV, I made sure the 6-pin cable was plugged in, I tried using the MOLEX adapters instead, I made sure the graphics card was properly seated, I don't have another PCIe slot to test it in, the slot works just fine for my old card anyhow, and perhaps most frustratingly of all the card shows up in the Device Manager if I boot in with the onboard graphics selected in the BIOS and it says it's working. It boots up just fine and stays running when I use PCIe instead, but it just doesn't display anything what-so-ever.

I'm running Windows 7, 8GB of RAM, AMD Athlon II X4 640(3 GHz), 500W PSU(I don't remember which brand) and I was using a Radeon HD7770 graphics card before trying to upgrade it.
