No cable connected/No signal connected

Hi, just finished putting together my first pc and as soon as I boot it up it says No Cable Connected when I used my hdmi cable, then I tried to boot it up with the vga cable connected to the motherboard and it said No Signal Connected. Don't know what to do, help pls.
BenQ GL2460 monitor VGA cable included
Asus Strix 970
Dynex Hdmi 5ft. Cable

you connected the video cable to the video card correct? the ones on the mobo get disabled when you have a dedicated card(970)

Yeah I connected the hdmi cable to the graphics card, and when that didn't work I tried connecting the vga cable to the motherboard

Is the computer beeping at you? do you get video if you take the video card out and plug it into the motherboard ports?

its not beeping it just goes straight to a black screen with No cable connected on it, but I haven't tried it without the video card

Ok I just tried it without a video card and it worked it went straight to the bios screen, does that mean my video card is defected?

You have THIS monitor?

Yes

But it has an HDMI port?

Are you sure you have the monitor set to the right input?

Also, have you tried a different cable?

I'm sure I plugged it in the correct hdmi port, the only other cable I have is a VGA cable and i don't have an adapter.

Found a possible solution.
