Maybe contact your ISP while you have your PC on. They should be able to run through the various Windows settings for the modem and your internet connection to get you up and running. There are so many arcane settings that you can't expect someone in the forums to be able to diagnose your problem(s).

Your new USR modem is probably using a different Com Port than the original modem did. You have a PS/2 mouse so remove the modem in Device Manager and disable both com ports (1 & 2) in the bios. Reboot, let Windows detect your modem and assign it an IRQ and Com Port.
