Go to Start/Settings/ControlPanel/Systems 
Check is there any yellow exclamation mark on the modem section. If yes, remove them by selecting the conflicting device, and click Remove. Remove all conflicting devices and shut down the system. 

Remove the card and start up the system until you see the desktop. 
Shut down the system. Insert the modem into the PCI slot. Restart the system. The system will detect the modem and will prompt you for the driver.

Check with your ISP is their Central Site Modem firmware updated.
