EVGA 680i LTISSUE! NEED HELP PLEASE

Hello! im new at building computers and this is my first build, I believe me and my friend set up everything corrently, But the only problem is on my monitor I dont get no display? Nothing shows up. THe fans are running, I see 3 lights on my motherboard, My PSU is working, Heatsink working, Video card seems to be working since the fan is running? Any guesses? is my board dead of out of box? I guess Bios is suppose to pop up right away if eveything is working properly. I was correclty grounded during installing compents, and Very careful. The only thing that shows up on my monitor is a box that say, Monitor is working , check cables and plugs....Its not the monitor b/c i plugged it back up to my old computer and it works perfectly fine. I need help.
