Although there are unlimited possible combinations of
hardware settings, you can trace most hardware
problems to a relatively small number of causes. Here are some tips for
troubleshooting some of the most common PC problems.
Your
computer is suddenly silent. Make
sure that you haven’t muted the sound. The sound card or adapter inside your PC
has failed or is no longer adequate for your needs.
Solution: Instead of opening the case, plug in an external sound
adapter such as Creative’s USB SoundBlaster Live! 24-Bit External, which
attaches to a
USBport on almost any desktop or
laptopcomputer.
Your
PC needs new or better wireless capability. You want to give your computer the ability to communicate
wirelessly with other devices, or you need to upgrade an outdated or
malfunctioning built-in Wi-Fi adapter.
Solution: Several manufacturers offer external Wi-Fi adapters and
antennas that connect to your PC through the USB port. One advantage of using
an external Wi-Fi adapter is that it usually comes with a more substantial
antenna than its internal equivalent, and you can adjust the placement of that
antenna to get the best transmission and reception in your home or office. The
latest “N” Wi-Fi technology adapters have a small footprint and offer better
coverage than earlier models do.
You
can’t install programs on a computer with no CD/DVD drive. If you own a minimalist netbook or a
small
desktopcomputer, the tiny size and low cost often come at the
expense of things like a CD/DVD drive. But without a CD/DVD drive, how do you
install new programs?
Solution: A couple of simple work-arounds are available. The first
and most obvious solution is to download programs or data over the Internet or
across a local area network or to use a device such as a flash memory drive to
transfer program content to the computer. You can purchase very large flash
drives to store up to 256GB worth of programs or data.
Another option is to install an external drive. Drives of this
type are small units, similar to those used in full-feature laptops, that draw
electrical power from wall current and connect to the computer through the USB
port.
