Apologies, I should elaborate: Elite K7SEM motherboard with 1525 conexant pci modem. (Yes, I know, buy a real modem)

Modems always seem a little flaky especially on reinstalls of the operating system. As a genereal rule of thumb I add one peripheral at a time after loading the operating system and always make the modem the last thing I install. I also make sure each item added works after a shutdown restart before adding the next component.
My best recommendation at this time is to uninstall the modem, boot up remove all modem devices, shut down restart, shut down reinstall the modem, install drivers, shut down restart and try it again. Good luck

For no dial tone, double check that the phone line is plugged into the correct jack on the modem.

Most modems disconnect the pass-through line to the connected phone.

If you connect the in-coming phone line to the pass through jack, the line is disconnected when you attempt to dial out with the modem.

Have you checked the communication port that is listed by the modem? Sometimes this can be a small but annoying problem. To check the status of the comm. port, go to the control panel, double-click on the modems icon and click the properties box ofthe said modem. There should be a drop down menu showing which port is being used by the modem.

Ultimately it might be easier and quicker to uninstall the modem and do a reinstall if you have the driver on a disk. Good Luck!

i think the modem is bad. if 'more info' works, i think you've proved the driver is installed ok. this 'no dial tone' is the most common failure mode of modems in my experience. the part inside the modem that switches the modem 'off-hook' has failed, imho. because it sounds like you are savvy enuf to make sure you have the phone line plugged into the modem in the 'line' port(as opposed to the 'phone' port.

Try running setup of the Modem and Drivers again,it is difficult to load the drivers after a format
