Hey,

I've installed Windows 7 yesterday and only one of my card seems to be working as it is the only one who displays something.

The weird thing is that when I plug a monitor in the DVI port in the other card, I hear that DING song that signals that hardware has been connected but nothing shows up.

Any ideas what could possibly be the problem?

Obviously, the three monitors were working under Vista.

Thank you very much,

jpidoo

Hey,

I did the reseat thingy with my card and I re-installed the ATI display driver and while it was installing, the standard windows 7 background showed up in my third screen, as if it was going to start but once the installation was over, it simply stopped working.

Any thoughts?

Thks for the help guys!

You have to disable Crossfire to be able to use any monitors connected to the second card.

Everything was fine regarding the crossfire setup. As stupid as I feel right now, stormy13 was right and I had to deactivate Crossfire X.

Thks everyone for the help!
