Chapter 25: Mastering Windows Media Center

Troubleshooting TV Tuner and Video Capture Problems

If you have problems with your video card or video capture card during Windows

Media Center configuration, you need to verify that you have the latest driver avail-

able from the manufacturer. You need to know the manufacturer of the card first,

and then download the driver file from the company’s web site. Once you have

retrieved the files, open Device Manager in Windows Vista and update the driver for

the card, as discussed previously for network cards.

This procedure fixes the majority of issues you’ll find with video cards. However, if

you continue to have problems, you will need to verify that the card works correctly.

Usually when you have video problems, you can identify them well before you load

the operating system. If a video card fails to work correctly, you will not see any

POST information from the system. If you are using a video capture or TV tuner

card, this does not always stand true, however. If you have problems with these types

of cards after updating the drivers in the operating system, you will need to move the

card to a different slot to verify that the problem follows the card. If the card works

in another slot, you need to check your motherboard for problems with the PCI bus.

Make sure to turn off the system completely by unplugging the computer from the

wall outlet before you attempt to remove or install any hardware devices. Chapter 5

provides additional information on device troubleshooting.

Troubleshooting Sound Problems

If you have problems with network settings and configuration during the Setup Wiz-

ard, this section describes how to overcome common obstacles and correct your

sound issues. First, you need to know what type of sound card you have installed on

your system. Second, you need to have the latest driver from the manufacturer. Once

you have retrieved the files, you need to open Device Manager in Windows Vista and

update the driver for the card, as discussed previously for network cards and video

cards.

Most of the time this will fix any problems you have with a network card. If this pro-

cedure does not fix the problem, you may need to verify that the hardware actually

works. You can do this by inserting a second sound card, or by running utilities

available online. If you continue to have problems when you add a new card, you

need to determine whether the slot in the motherboard is working correctly. Move

the card into a new slot and see if Windows Vista picks it up after you reboot. Make

sure to turn off the system completely by unplugging the computer from the wall

outlet before you attempt to remove or install any hardware devices. Chapter 5 pro-
