The modem must be using some services of the Windows operating system due to which the system is getting hung up when the modem is connected to the system. Hence the best practice would be to shut down the modem first and then shut down the computer. Also try and get the Windows installation on your system repaired and see if the problem is solved.

Disconnect your modem first and they try to shutdown your computer. If that works then it means that some system file of the device is engaging the system behind. Try this. Right click on My Computer > Properties > Hardware > Device Manager and in the list right click on the modem. Then choose update drivers. If you have a cd then provide the same.
