    • In this chapter, CompTIA expects you to understand the
      procedures for adding, removing, and configuring
      internal storage devices, motherboards, power supplies,
      CPUs, memory, and adapter cards. In addition to
      installing the hardware components, you should
      understand how to install device drivers. Also be
      prepared to describe how to adjust hardware settings.
      All network-specific installation and configuration issues
      will be presented in Chapter 13.

   Chapter 4, Troubleshooting and
    Maintenance for PC’s, Test Objectives
    • 601: 1.3 602: 1.2 603: 1.2 604: 1.2 Identify tools,
      diagnostic procedures, and troubleshooting techniques
      for personal computer components
    • For the A+ exams, CompTIA requires that you
      understand troubleshooting theory, procedures, and
      techniques. First learn the theory, and then learn how to
      apply the theory using techniques and procedures
      appropriate to the symptoms and identified problem
                Chapter 3 Key Points
   Installing Motherboards, CPUs, and Memory
    •   Select motherboard, CPU, and memory modules that are compatible with each other by
        researching the specifications of each.
    •   A motherboard must support both the technology and the form factor of a memory module,
        such as SIMM, RIMM, or DIMM.
    •   When installing a motherboard, follow the instructions in the motherboard manual.
    •   The ability to upgrade an existing CPU depends on the limits of the motherboard.
    •   One of the most common and most effective PC upgrades is the installation of more RAM.
    •   The CMOS settings program enables you to alter the behavior and configuration of many of
        the PC's components.
   Adding, Configuring, and Removing Power Supplies
    •   Replace a failed power supply.
    •   Select a power supply that is of the correct form factor for both the motherboard and the
        case, and select one that has sufficient wattage for the components you expect to have in the
    •   Older ATX motherboards used a 20-pin ATX (P1) connector to provide power. Some recent
        motherboards require two ATX12V 2.0 connectors—one is a 24-pin main connector, and the
        other is a 4-pin secondary connector. Other newer motherboards require EPS 12V connectors,
        which include a 24-pin main connector, an 8-pin secondary connector, and an optional 4-pin
        tertiary connector.

   Adding, Configuring, and Removing Cooling Systems
    •   An overheated PC will slow down, stop functioning altogether, or become damaged.
    •   The typical PC comes with a cooling system adequate for the standard components delivered
        with it.
    •   Supplement the cooling system when adding hard drives, memory, and additional expansion
        cards, or if the PC must function in a hot environment.
   Adding, Configuring, and Removing Storage Devices
    •   EIDE drives come with either a PATA interface or a SATA interface.
    •   Most computers have two PATA channels that can each support two EIDE or ATAPI drives.
    •   Each PATA channel can have one master device, or one master and one slave device, and you
        must configure each device on a PATA channel for its role on the channel.
    •   Only one SATA device connects to each SATA channel, so there are no configuration issues.
    •   While most new PCs do not come with floppy drives, most motherboards have a single
        channel for floppy drives, which can handle up to two floppy drives.
    •   Normally, manufacturers do not build SCSI systems into the typical PC. If you want to add
        SCSI devices to a PC, you need to install a SCSI bus adapter.
    •   There have been a huge number of SCSI standards and variants, and most of them use
        special parallel connectors of various sizes. There are newer SCSI devices that will connect to
        SATA channels, but they also need a special host adapter.
    •   Various external storage devices, such as those with USB or IEEE 1394, are available today.
        These devices are truly Plug and Play, and once one is plugged in, the system recognizes it
        and assigns it a drive letter.
    •   To remove one of these external devices, use the Safely Remove Hardware icon on the tray
        area of the Windows taskbar to stop the device, and only after it is stopped, unplug it.
    •   To prepare a hard drive for use you must first partition it, and then format it for a specific file

   Adding, Configuring, and Removing Adapter Cards
    •   Select an adapter card that will add the functionality you need and that also fits an available
        expansion port on the motherboard.
    •   Read the documentation for the adapter card and the motherboard before installing the card.
   Adding, Configuring, and Removing Displays
    •   Upgrade from a CRT to an LCD to gain more desk space.
    •   Add a second display in order to spread the Windows desktop across the real estate of two
                   Chapter 4 Key Points
   Troubleshooting Theory and Techniques
    •   Perform backups of data and the operating system before making any changes.
    •   Assess a problem systematically, and divide large problems into smaller components to
        analyze individually.
    •   Verify even the obvious, determine whether the problem is something simple, and make no
    •   Research ideas and establish priorities.
    •   Always document your actions, findings, and outcomes.
    •   Perform diagnostic procedures in a logical order.
    •   Identify the problem and analyze it to determine whether it is hardware or software. Then
        apply troubleshooting techniques appropriate to the problem type.
    Chapter 4 Key Points (Con’t)
   Troubleshooting PC Component Problems
    •   Procedures should move from least intrusive to most intrusive, checking the following: proper
        connections, appropriate components, drivers, and settings, and component seating of
        internal devices.
    •   When troubleshooting a video or audio problem, start with the most accessible component,
        check to ensure that it is getting power, and that it properly connects to the computer.
    •   POST error codes, such as 1**, 2**, and 3**, can indicate system board, memory, or
        keyboard failures, respectively.
    •   Incorrect CMOS settings can affect a variety of system components. Check and correct these
        problems by running the system setup and changing the settings.
    •   CMOS batteries last from two to ten years. A computer that does not maintain the date and
        time when it has been powered off is a symptom of a failed battery.
    •   Most system board, processor, and memory errors are fatal, meaning that the computer
        cannot properly boot up.
    •   Motherboard errors can be the most difficult to pinpoint and, due to the cost and effort
        involved in replacement, should be the last device you suspect when a subsystem or the
        entire computer fails.
    •   Most floppy drive problems are with the media (floppy disks) rather than with the hardware. If
        you find a floppy drive problem that cannot be easily corrected, consider replacing it with an
        external USB floppy drive.
    •   USB device problems may involve power connections for external devices that require external
        power. Consider using a USB loopback plug to diagnose a stubborn USB problem.
    •   Problems with SCSI devices, beyond failure of the device itself, most often involve termination
        of the SCSI chain and SCSI device ID.

   Troubleshooting Tools
    •   Arm yourself with appropriate troubleshooting tools, including software and hardware tools.
    •   If you must service a large number of PCs, consider investing in a specialized diagnostic
    •   Acquire and learn how to use appropriate cleaning products, such as cleaning wipes, antistatic
        display cleaner, canned compressed air, an antistatic vacuum cleaner, and non-abrasive
        cleaning compounds, such as isopropyl alcohol.
   Preventive Maintenance Techniques
    •   Schedule regular preventive maintenance, such as visual and audio inspections, driver and
        firmware updates, cleaning, and verifying maintenance of a proper environment.
    •   Schedule regular maintenance for various components, such as displays, power devices, and
        drives. Protect thermally sensitive devices with regular cleaning, and by ensuring that there is
        proper airflow.
