No Display Detected

Hey guys I have a problem with my evga gtx 750. I just got it from a friend and it's a slight increase in performance compared to my previous card so I just took it. The problem came when I plugged the card into my rig. There was no display detected HOWEVER I'm pretty sure the card is not dead. I plugged it into my older rig and the display (same monitor used) worked and it detected the graphics card.
I booted into my rig using the onboard graphics as the display and went to device manager while the graphics card was plugged into the mobo. It detected the gtx 750 and I even installed drivers for it. But when I connected my monitor to the graphics card, there was just a black screen and nothing else.

*update:
the ez debug led on the motherboard, lights up at the vga part

Here are my Specs:
Intel i5 6600 (non K)
MSI H110m - Gaming
2x4 gb Ripjaws V
Seasonic M12-ii 520w
Western Digital Blue 500 gb

Thank you for taking the time to read this

Leave the card plugged in and shut down the computer. Open up the case and pull the coin battery for thirty seconds to reset the CMOS.

Sometimes motherboard don't like hardware changes without a quick reset.

It didn't work Apparently my mobo has this ez debug led thing and for a while, it was blinking red on the part that said vga. I read the manual on the mobo and it said it only does this if the graphics card isn;t detected or failed.
