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 (661) 322-2122.
  • 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.
