connecting 2 vdus to a pc running windows 2000 server

I have a pc running on windows 2000 server and was connected to two screens, one using a special connector.The pc developed some proplems and win 2000 server was reinstalled. The screen connected by connector could not communicate with the server after installation of win 2000 server.
Please help me, does it require special drivers to enable communication with the main cpu or how
do i configure it to work ?

There is no original cds,for this system how and where can i download the drivers if they are required ?
