How do I remove a computer modem?

Updated: 01/24/2018 by Computer Hope

Most internal modems are built directly onto the motherboard of your computer, making them irremovable. If you do have one of the removable variety PCI, ISA, or PCMCIA follow the steps below for removing most computer modems.


You can deactivate your integrated modem in CMOS setup, which allows for the installation of a PCI modem.


Before you begin, it is necessary to ensure that you reduce or eliminate, the risk of electrical charge damaging any of the hardware in the computer. The best way to do this is by wearing an anti-static wrist strap. While inside the computer, make sure it is disconnected from power and that you are familiar with ESD (electrostatic discharge) and its potential dangers.

Open your machine

After you have removed the power cord, you need to remove the side panel from the computer case. The side panel is usually held in place by several screws, or it may be held in place with a bracket or clamp of some kind. Remove the fasteners securing the side panel, and carefully pull it off. Once the panel is removed, you should be able to see the inside of the computer, which look something like the image below.

The modem is usually located in the bottom of the case, on the left side (circled in red above). You may see other hardware cards there as well (e.g., video card, sound card or network card).

Removing the modem

Each of the hardware cards, including the modem, is attached to the computer case by either a screw or clamp of some kind. If held in place by a screw, remove this screw for the modem card only. If held in place by a clamp, release the clamp. The image below shows a modem card held in place with a screw.

Mounting screw

With the appropriate screw removed, carefully pull the modem card out of the PCI card slot on the motherboard.


When removing hardware from a PCI slot, it is better to use two hands, so there is equal force being applied to both ends. It is also helpful to use a soft "wiggling" motion to free the card.
