New computer build, fans & evrything runs but no video - Gigabyte mobo

Hi, I just finished my first ever computer build and went for it's first boot up. I connected the DVI cable to my monitor and booted it up. Everything seemed to go well and all the fans, hard drive, and everything else seemed to be running well. I waited and waited but I got no video on my monitor. I was confused because when it booted up, the speaker gave a single short beep, which from what I read is a successful post. I was searching around on the Internet to see what my problem was. I tried booting it with a single stick of RAM in different DIMM slots but that still didn't work. I even tried breadboarding using just the CPU and HSF but the speaker just made continuous short beeping noises. I installed a stick of RAM and the beeping went back to the single short beep. I even went through The entire list of no boot up/no video forum, http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems , but nothing helped seemed to help me. Please help me cause I wanna use my newly build computer ASAP :((((

  1. I'll ask the stupid question first:

    did you plug the video cable into the motherboard video port or the video card video port? because you should use the video card's port

    I plugged the cables into both the motherboard ports and the video card ports
  3. ok, video card port is what you should use.

    try testing the card in a different computer (maybe a friend's?) to see if its the card. if that works, then its not the card.with the card out, try the motherboard video
