  1. You should never update the bios, unless you are trying to solve a specific known problem.
    You will probably get it going with a new board, and reloading the OS.
    As far as the old board, the bios is probably caved.
  2. the problem is the Video Card isnt working with the new mobo.

  4. Try to check your video card to another pc. Bios update do not solve video card working issue. Maybe the card or the pci-e slot is faulty.

    install hardware
    turn off all security and turn off firewall
    set the bios to boot DVD drive first
    put win 7 disk in the drive, start the computer
    select upgrade
    this reloads the OS and configures the hardware
    but does not erase your personal files or programs.
    your hardware is not configured.
  7. Then there is video card issue i think. Did you connect display cable to the gpu?

    I have no display at all. The video card is running but no signal to monitor.

    My mobo doesnt have a vga/dvi/hdmi output.
  10. Check the monitor cable if it is connected correctly.

    Did you try all the video outputs on the card?
    there is usually more than one, try them all
