Did you connect a 6-pin connector to both cards?

Did you try swapping the cards in slots? Like, make the top card bottom one and vice versa.

Did the same card would stop working? Or the card in a particular slot?

Looks like bad bridge indeed if it cannot detect either graphics card.

what happens if you put the old mobo back in. both cards work ?

my old mobo only has one bus port reason for me buying a new mobo with 3 bus ports

trying to find out if both cards still work and trying to see if the new motherboard is shot.

when you put the new board in did you also install the motherboard drivers off the disc that came with it? and did you reformat the hard drive ( new install of opsys ) or did you just try and swap the drive with everything on it ?

1.i tried to install the drivers from the disk but it was doing something really weird and it wouldn't work
2.i just swapped the drive with everything on it then reinstalled windows

you need to install those drivers for one. you should also do a complete reformat and install. carry overs don't usually fare well.



does ot boot with 1 card in ?

did you try clear cmos once ? doubt that will help.
