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.

The problem is the video card isnt working with the new mobo.

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.



I just bought a new mobo today and the video card still doesnt work.

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.

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