Video card does not send video to display?

[thejuice101]

I have a relatively old card, a geforce gt 630 and I tried it in my Gateway, win 8 rig and I plugged in all the cables correctly. But my monitor received no signal? I had to remove the card and hook the VGA back into the integrated ports and it worked. I let a certified PC tech take a peck at it but no luck as well? I gave up and thought, what the heck? So I through the thought "DOA" card into a 2007 vista rig and it worked?! Boosted windows rating from 3.0 to 4.5! Anyways, why didn't the card work in my more modern rig?

You have to change the primary display adaptor setting in your bios. It defaults to the apu because they assume that as you bought an apu you bought it to use the integraded graphics

I did a little research and fixed the problem. I had to go into the Win 8.1 bios and disable "Secure boot" under the Authentication tab. Once doing so I had to go to the Boot options tab and check the "Launch CSM" option to 'Always' and make sure the Video OpRom is set to legacy. Once doing this I had to save and exit, shut down the PC and install the card.
