I have just recently finished putting together my first custom pc. I have an ASUS M5A97 mobo. I also have msi radeon 7770 hooked up to an hdmi cable to a tv. When I power it up you can hear the hard drive and optical drive start up. There are no ram failure lights and all the fans run smoothly. When I look to my tv, nothing happens. Can you guys please point me in the right direction, thank you.
