Troubleshoot hardware problems
Published: September 7, 2006
There are thousands of different models of printers, digital cameras, network adapters, and other hardware accessories (generally referred to as devices) that you can use with a computer running Microsoft Windows XP. Most of the time, you can install and begin using a device right away. Occasionally, however, you might encounter a problem during installation or even when using a device that previously worked.
If you run into a problem with your hardware, you may be able to solve it by trying these three things:
Troubleshooting problems with new hardware
When installing new hardware, it is important to follow the manufacturer's instructions exactly, even if they seem counter-intuitive. For example, it may seem logical to connect your new hardware to the computer first. However, many hardware accessories require that you install software before you connect the hardware. Before turning on your computer or connecting anything, read the instructions.
If you don't follow the steps in the correct order, Windows XP may not install a device correctly. However, you can usually resolve installation problems by disconnecting the hardware, removing the software, and then following the manufacturer's instructions to install the hardware. Also, if you receive a message requesting that you restart your computer, always do so before continuing.
How to reinstall hardware
The best way to resolve hardware problems during setup is to completely remove the hardware and software. Then, start over by reinstalling the hardware according to the manufacturer's instructions.
To reinstall hardware
1. | Visit the hardware manufacturer's Web site and download the latest software and device driver for your hardware. Note: A driver is the most essential software, because it contains information and instructions that enable Windows XP to interact with the device. The most common problems often lead back to an outdated, mismatched, or improperly installed device driver. If you suspect the problem is with your device driver, read Troubleshoot device driver problems. |
2. | Shut down Windows XP and your computer. |
3. | Disconnect the hardware. |
4. | Start your computer. |
5. | Uninstall all software related to your hardware. |
6. | Remove the device driver by following the instructions to reinstall a device driver. |
7. | Restart Windows XP. |
8. | Follow the manufacturer's instructions to install the hardware. |
If reinstalling the hardware with the latest software does not fix the problem, read the next section to determine if you have faulty hardware. If the problem persists, contact the hardware manufacturer for assistance.
How to identify a hardware failure
Sometimes, a device is broken, and the only way to fix the problem is to replace it. However, you should first see if the hardware failure is caused by:
| • | Improperly installed software. Try reinstalling your hardware. |
| • | A faulty port. Connect the hardware to a different port or connector if one is available. For example, if the device uses a USB connection, plug the device into a different USB port, and then reinstall the hardware. If the device works, the problem is with your computer's port, not with the hardware. Contact your computer manufacturer for repair information. |
| • | Computer configuration. Attempt to connect the hardware to a different computer, if one is available. If the hardware works when connected to a different computer, the problem is related to your computer's configuration. Instead of exchanging the hardware, you should contact either the hardware manufacturer or your computer manufacturer for additional troubleshooting assistance. |
If the hardware fails when connected to a different port on your computer and to a different computer, the cause of the problem is most likely hardware failure. If the hardware is within the warranty period, contact the manufacturer for information about exchanging the hardware. Otherwise, contact a computer repair shop for help fixing the device. Keep in mind that inexpensive hardware, such as a webcam, may be less expensive to replace than to repair.
