Try putting the modem in a different pci slot or isa slot and see if that helps. Is there any where you can change the com port in your settings like a modem option in control panel. Sometimes you can change the com port and that should help. But if you cant then there is no way of changing it. I know in win2000 you can change the com port. Also when you install the drivers check dont detect modem. Then after that check have disk and it should then recognize the drivers.
