Hello. So I am going to make this simple. I am building my first PC, and I have the NZXT Phantom case, AMD Phenom II CPU, ASRock ATX Socket AM3, a 1 TB H-D-D, and a Radeon 7770. Everything fits fine. So I boot up my PC (I have reset my CMOS multiple times) and I hear the fans whir, the CD drive opens and closes, the Phantom's LEDs even light up. But when I look at the monitor nothing appears (no BIOS boot screen, I press the DEL, F2 and F12 keys too). I have the monitor plugged into the Radeon's graphic port. Any help?
