Chapter 4 Flashcards
Dusty environments, such as
construction sites, requires more attention than an office environment.
Computer Location or Environment
High-traffic networks, such as a school network, might
require additional scanning and removal of malicious software and
unwanted files.
Computer Use
Storage device problems are often related to loose, or incorrect cable
connections, incorrect drive and media formats, and incorrect jumper and BIOS settings.
Storage Device
These problems are often caused by incorrect or loose
cables, failed components, incorrect drivers, and corrupted updates.
Motherboard and Internal Components
Power problems are often caused by a faulty power supply, loose connections,
and inadequate wattage.
Power Supply
Processor and memory problems are often caused by faulty installations,
incorrect BIOS settings, inadequate cooling and ventilation, and compatibility issues.
CPU and Memory
Display problems are often caused by incorrect settings, loose connections, and
incorrect or corrupted drivers.
Displays
Make notes as you go through the troubleshooting and repair process. Refer to
these notes to avoid repeating steps and to determine what needs to be done next.
Notes
Include descriptions of the problem, possible solutions that have been tried
to correct the problem, and the steps taken to repair the problem. Note any
configuration changes made to the equipment and any replacement parts used in the
repair. Your journal, along with your notes, can be valuable when you encounter similar
situations in the future.
Journal
Make a detailed list of problems and repairs, including the date,
replacement parts, and customer information. The history allows a technician to
determine what work has been performed on a specific computer in the past.
History of Repairs
The fan should spin freely, the fan power cable should be secure, and the fan should turn when the power is on.
CPU heatsink and fan assembly
The modules must be seated securely in the RAM slots. Ensure that the retaining clips are not loose.
RAM Modules
A loose screw in the case can cause a short circuit.
Screws
Examine all cable connections. Ensure that pins are not broken and bent and that cables are not crimped, pinched, or severely bent. Retaining screws should be finger-tight.
Cables
Ensure that they are seated properly and secured with the retaining screws in their expansion slots. Loose cards can cause short circuits. Missing expansion slot covers can let dust, dirt, or living pests inside the computer.
