Installing a USB Expansion Card into An Old PC

1. On the back of the computer, each of the cards installed present a new function for the computer. For instance, one card allows this older computer to access the Internet while another adds monitor support. As you can see, there are two USB expansion cards installed and each has two ports. To begin, unplug everything from the computer tower.



2. Open the case of your computer, by pushing in on a release button, removing screws or pulling back or up on the side/top of the case. Your owner’s manual should tell you how to remove the case if you have trouble (some of them can be tricky).

   

3. Find an open PCI slot on your motherboard. As you can see in the picture, this computer has five open slots. The open areas on the end are where the USB ports should poke out from the computer case. If those are covered, you can remove the slats that cover them by unscrewing and pushing on the cutout. Each card should have a single screw in the top metal of the case.  

   

4. When you push in the card, start from the end furthest from the case and work your way in. The card should be mostly parallel to the slot. Push the card in firmly, and then screw in the supporting screw.

   

5. Replace the cover to the case, plug in the computer, and power it on. It should automatically recognize the USB expansion card. Do not plug in USB devices until you have powered on the computer after installation – this may interfere with the card installing properly.

NOTE: When you’re handling the inside of your computer, you should always ground yourself to keep static electricity from surging into the motherboard. You should also work on a static resistant surface, like a tabletop.

The Future of USB

The upcoming USB 3.0 technology incorporates a piece of fiber optic that will work with older copper connections. The move to USB 3.0 should quench the thirst of storage junkies and other savvy users. The move will likely mean very fast transfer rates from portable devices to a desktop. This could facilitate new technology for mobile users, as we can move data quicker between devices.

The future of USB technology hinges on the success of USB 3.0. Assuming Intel pushes everything out as planned, it should be business as usual. We’ll likely see this next version enjoy the long shelf life granted to its predecessors.
