Black Screen After GPU Install Please Help!

[JustMeelz]

So let me get right into this: I bought an EVGA GTX 1050 Single-Fan. The original install was very painless and easy, then, I released that the card didn't support VGA, and neither did the motherboard (I have an Asus ROG G20AJ). So I went out, bought a used DVI cord, but when I plugged it in to the card and the monitor, still no signal. Even after repeatedly switching my old then new card multiple times it was still no signal, even on the old GPU with my old VGA cord, I'm currently getting a HDMI adapter (My monitor doesn't support HDMI) so I can connect my monitor to my motherboard not my GPU, so that is on its way. Any help I can get that would be LIFECHANGING and more than AMAZINGLY accepted.

okay this is the rear of your computer right ? questions below

1. do you have the 180w and 230w power cables connected to your PC, if not then likely your VGA card is not getting enough power
2. the system comes with an internal motherboard HDMI connector. which would lead me to think since your running Intel I7
to plug your video card in, and boot to bios and look is the default video card is IGP instead of PCIE if so save and reboot.
3. what video card did you have before ?
