I just finished my first build and now when I try to boot it up, I get no image on the screen. All the fans run, the hard drive is moving and the CD-ROM drive is lighting up and it opens and closes. The CPU cooler fan twitches a every couple seconds but goes into rotation but I read somewhere that it is normal with a Gigabyte motherboard. I'm also not getting any beeps or anything. Do you guys have any suggestions on how to fix this?
