Quick Suggestions

• Do not be afraid to make a mistake but use common
  sense.
• Research the Web for answers to your questions.
• Check locally for computer classes. CTAP is an
  excellent resource. Also, one can call CompUSA
  at [phone].
• De-static yourself before working on electrical
  items. This can be done by discharging yourself
  on the units case prior to working on it or,
  preferably, by wearing a special copper wrist
  band that is attached to the units case.
• Avoid wearing only socks and plastic shoes on a
  carpeted surface. Static will surely build.
• Join a computer club, such a KIPUG, Kern
  Independent PC Users Group - see
  lthttp//www.kipug.orggt for details.
