modems

start by loading the driver for the modem onto the pc. Then go to add new hardware and tell it what type rather than having it look for it. tell it you have the disk and load the new driver in. Reboot and whalla should be good to go.
Good luck

Depending on the model of the CPQ PC, the driver may be found on thier website. http://www.compaq.com/support/files
I realize you probably can't get to the web since your modem isn't working so go to the library or a friends house and download it there. Once you have the driver run the install. Reboot when it says to and it should detect the modem. If it doesn't go through the add new hardware/modem process and see if the PC detects it.

hello,
open the case and physically remove the modem. then look for the processor chip... it is black and square... there are identifying numbers or symbols on it... go to the compaq site and find the corresponding numbers on there driver pagefor modems.... you can also go to "driverguide.com"; and "driverzone.com" and follow the site search for your modem.... you can also do an "fcc" search on the driverzone site. look for the "fcc i.d. number on your modem, they may be on the back side...but make sure it is the fcc ID number...not the registration number.... this will provide you with the exact information for retrieving the correct modem driver from compaq. put the downloaded driver in a separate folder and then open the driver file. when queried for the driver, go to the folder containing the downloaded driver file and it should recognize your modem. email me if you need any more help or a further explanation
