Preventive maintenance involves systematically inspecting equipment to detect and correct potential failures before they occur or become major defects. This helps maintain equipment in satisfactory operating condition and contrasts with corrective maintenance which repairs equipment after a failure. The document then provides solutions to common computer issues like hard disks not being detected, no sound, missing desktop icons, a mouse double clicking on its own, and thanks the reader.

troubleshooter to fix the problem. It
checks for common problems with the

2.Many computers have three or more
jacks that connect to a sound card or
sound processor, including a
microphone jack, line-in jack, and line-

plugged in to the line-out jack. If you're
not sure which jack this is, try plugging
the speakers in to each of the jacks to
see if any of them produce sound.
