108 Chapter D Optimizing Your Audio Computer System
Another common problem is loose internal computer connections, which commonly
occur after transporting the computer. Keeping the possible consequences to your
warranty in mind, as well as all safety precautions, you may wish to refasten the internal
connectors, with care. Be careful though: disconnect the power cable first, and wait for
the high voltage to drop. Ground yourself to the computer with an anti-static strap, or
by touching the metal components of the case. This can prevent visits to the repair
man (or the hospital).
Viruses
Regrettably, there are some malicious people who program and distribute viruses,
solely to cause damage. Check your drives regularly for viruses, especially if you are in
regular contact with other people’s data carriers, or download data from the Internet.
Not all virus programs are able to detect macro viruses, and others which are, as yet
unknown, to virus protection software developers.
Re-installing or Updating the Operating System
It is possible that as a result of a crash, or installation error, the operating system will
become unusable. If this happens, re-install the operating system from your system CD-
ROM.
To do so, restart your computer using the Mac OS X Installation CD (insert the CD and
select it as the “Start volume” in the corresponding control panel; or on newer Macs,
simply press Command
during the restart) and re-install the operating system.
Sometimes, the problems simply come down to the operating system. You can usually
find updates for your operating system online, where they can be downloaded free of
charge.
Formatting the Hard Disk
Formatting the hard disk is the absolute last resort you should attempt, before sending
the computer for repair. This will erase all files on your hard disk, and any “garbage”
data that may be causing your problems.
The formatting process will erase all files, so make backups of all files and programs first,
and verify these backups to ensure that they have been successful. Be sure to run virus
checking software on all backups, to avoid re-infecting your newly formatted drive with
any viruses that your system may be carrying.
To format the internal hard drive, you will need to start your computer from another
drive, either from the CD-ROM, a boot floppy, or an external hard disk. To rule out a
virus problem however, it is advised that you reformat all hard drives in the same
session—a CD-ROM cannot be infected with a virus (unless it was infected to begin
with).
Important: Please keep in mind that invisible software authorizations cannot be
copied—please de-authorize such applications from your hard drive before erasing it!
