Issues with 7870

Hello, I'm in need of help.
My Gigabyte HD 7870 is not working at all. I'm trying to use it with an ASRock Z77 Extreme and my Polaroid television (by HDMI). It freezes at the beginning of the post screen. Any input is well appreciated!

  4. I've even tried the other PCIe slot (the third one has the psu in the way).
    I've also already installed the drivers and everything.
  5. AHH I really could use help here. I'm hoping it is just the crappy television.
