    try making sure the mb bios is up to date..if it not a bios issue then it a power issue. check that the right 4/8 pin cable for pci power is connected to the mb and make sure if the video card has two 6 pin or two 8 pin power both of them are plugged in. if they are check your ps and the 12v line. some ps have more then one 12v line and sometime cant handle the load of a high end gpu.
  2. The 2x4 pins connectors are hooked to the MB. One 4 pin is marked with a B. The other is marked with a W. Is it possible that they have to be on a certain side of the 8 pin connector? I havent tried to swap them yet. With the GPU installed the fans come on but cant get anything to come on the screen, even the onboard doesnt work until you remove the GPU.
  3. I guess i have a bad video card. Hopefully Newgg will get me a new one soon
  4. I just tried a Geforce 460 and it does the same thing. No video at all
  5. You have to go in the BIOS and disable onboard video. don't listen to this retard

    make sure before you rma the video card the bios for the mb at it newest rev. there been a lot of bug fixes for the z77 mb.
  7. Thanks for the replies but apparently one of the 4 pins wasnt connected good or something. Finally got it to work. You guys are awesome.
