1. Basic Preparation

Part 1 – Things You Need Before Beginning

Tools:

• Hardware

• Software

1.1 Troubleshooting Methodology

A good PC technician will follow some sort of

formalized troubleshooting methodology

Example 1: Basic 3-Step Plan

• Step 1: Assemble the proper tools

• Step 2: Backup everything before making changes

• Step 3: Analyze, test, and document

1.1 (Cont’) Example 2: Basic 5-Step Plan

Step 1: Information Gathering

• Identify what you want to accomplish (Maintenance, Upgrade, Repair)

• Identify the component to work on.

• For repairs: Identify any symptoms, determine if anything has changed, and establish probable cause

Step 2: Create an action plan

• For maintenance and upgrades: tool gathering, backup, parts identification, and action

• For repairs: there is an step at the begging: “try a quick fix”

Step 3: Implement and Test the Solution

• Again, if you are performing a repair, try a quick fix and then try the most likely solutions first.

Step 4: Identify the results and effects of the solution

• Did the upgrade work? Did the maintenance work as expected? Did the repair fix the problem?

Step 5: Document the solution and process

Point of a Plan: 1) Don’t forget anything, 2) Can recover if you do, and 3) Can repeat the process

1.2 Backup, Backup, Backup

• The most important PC component is…

DATA!

So backup before BEFORE you begin.

Keep the data safe.

1.3 Tools – Hardware/Software

• Tool Kits: A computer tool kit; possible non-standard “security” bit set

• USB devices:USB-to-HD adapter; USB flash or hard drives; USB Floppy Drive

• Part 3 – CCleaner

2.3 Fragmentation

What is D i s k F r a g m e n t a t i o n?

DEMO: White-board Session

Hard drives store files in pieces, sometimes called blocks or allocation units.

Fragmentation occurs when the operating system cannot or will not allocate

enough contiguous space to store a complete file as a unit, but instead puts

parts of it in gaps between other files (usually those gaps exist because they

formerly held a file that the operating system has subsequently deleted or

because the operating system allocated excess space for the file in the first

place). Larger files and greater numbers of files also contribute to

fragmentation and consequent performance loss. (Source: Wikipedia)

2.3 (Cont’) Defrag

Defragmentation (and disk optimization) attempts to:

• Rearrange files so that all their parts, or blocks, are

contiguous (sequential)

• Rearrange programs, so that the most commonly

used programs are at the front of the drive and

launch quicker

Tools to Defrag:

• Windows Built-in (“Disk Defragmenter”)

• 3rd Party (Defraggler, Norton SpeedDisk, JkDefrag)

2.3 Fragmentation - Demos

DEMO

Windows Defrag program

Tip: Run a CHKDSK or SCANDISK before performing a Defrag

Accessing Disk Tools:

• Right Click on the Drive (from Explorer or “My Computer”),

select Properties, click on the Tools Tab.

• Defrag: Start Programs Accessories System Tools

Disk Defragmenter

2.4 Windows Registry

What is the Windows Registry?

A centralized database that stores all the settings for

Windows, including:

– Hardware Information and Settings

– Software Information and Settings

– User account settings,

– Security settings

The registry replaces the old flat or text files of yesteryear:

*.INI, AUTOEXEC.BAT, CONFIG.SYS

2.4 Windows Registry - Hives

Registry settings are split into sections called “Hives”

Common Hives:

• HKEY_CLASSES_ROOT – stores information about registered

applications, such as file associations

• HKEY_CURRENT_USER – setting of the currently logged in user

• HKEY_LOCAL_MACHINE – local computer settings

• HKEY_USERS – subkeys of HKEY_CURRENT_USER

• HKEY_CURRENT_CONFIG – information gathered at runtime

(when you boot)

2.4 Registry - Pros and Cons

Advantages:• Centralized. If there is a setting in windows, chances are it is

referenced in the registry.

• Keeps configuration details largely transparent from users

• Standardized method for how program storm data in the registry.

• Easy to backup

• Read in faster than a text file*

Disadvantages:• Hard to backup individual application settings

• If it gets too big, it will slow down boot times and increase a system’s

memory needs

• Complex to navigate.

• Hard to keep clean, easy to corrupt, hard to repair.

2.4 Registry – Corruption Causes

The most common reason for registry corruption:

Invalid references/entries in the registry.

Including, but not limited to:

• Added/removed programs (Uninstaller References)

• Temporary file references

• Deleted files

• Invalid file formats

2.4 Registry – Repair Methods

Manual: • regedit.exe,

• *.REG files (also called a “REG bomb”),

• Command Line

Automatic:

• Registry Cleaners (CCleaner, Glary, Symantec/Norton 360, Fix-It, etc.)

Disadvantages of Registry Cleaners:

• They can remove things they are not supposed to

• There are a LOT of fake registry cleaners out there that simply deliver

viruses, malware, spyware, “scareware” to your system.

2.5 System Software Updates

Software Update Best Practices and Tips

• Windows Update / Microsoft Update – Just Use It.

• Keep Microsoft Automatic Updates turned on.

• Check Monthly for “Optional” Microsoft Updates

• Do not install drivers from Microsoft (unless you are

having issues with a specific piece of hardware)

• Let your security software check daily for updates

• For non-Microsoft products, check at least monthly

(or based on your system power)

2.5 System Updates - Demos

• Automatic Updates

• “Optional” Window Updates

3. Basic PC Security

Part 3 – The “3-Pronged” Approach

1. A Firewall (Hardware or Software) – Section 3.1

2. Anti-Virus Software – Section 3.2

3. Anti-Spyware Software – Section 3.2

Additional Considerations:

• Internet Browser Security – Section 3.3

• Security vs. Usability – Section 3.4

3.1 Firewalls

What does a firewall do?

Blocks unauthorized access to a system, while permitting authorized

communications. Two typical actions on data:

Permit

Deny

• Hardware firewall = (typically) mean better performance than software

• Software firewall = may be more configurable than hardware firewall.

A Software firewall is essential for a mobile computer.

• Free Products: Windows Firewall (at the very least), ZoneAlarm Free

• Commercial Products: Anything bundled with an A/V suite

(Norton 360, McAfee I.S., ZoneAlarm I.S., etc.)

3.2 Anti-Virus and Anti-Spyware

What is the difference?

• Viruses can (typically) reproduce.

• Viruses are designed to cause problems,

and spread.

• Spyware/Adware (typically) cannot reproduce.

• Spyware/Adware programs are more for tracking.

Tips:

• Choose a reputable vendor.

• Don’t believe Internet ads and Pop-up (“Scareware”)

4. Basic Peformance Enhancement

Part 4 – Additional Performance Topics

These already coved topics can affect performance: • Temporary Files (Section 2.2)• Hard drive Fragmentation (Section 2.3)• Registry Settings (Section 2.4)• Firewalls (Section 3.1)• Viruses or Spyware (Section 3.2)• Security over Usability (Section 3.4)

There are also a few other places you can look for “basic” performance boosts:

• 4.1 Display Settings• 4.2 System Update Frequency• 4.3 Virtual Memory• 4.4 Physical Memory

Note: there are many, many, more advanced performance hacks for Windows.

This section shows a tiny subset of system tweaks, just some “Basics”.

4.1 Display Settings

Pretty Graphics

= More System Resources

You can make your Windows interface more responsive by turning

off all the animated interface features (ex. Vista’s Aero)

This called Windows Classic mode. You can make any XP or

Vista PC’s interface similar to the classic menu and theme that

started with Windows 95 and WindowsNT 4.0.

Right Click “Computer” or “My Computer” select “Properties”

Tabs: Advanced Performance (Settings) Visual Effects

You also adjust many of these settings in the

Start Menu and under Display Settings

(Note: Demo after section 4.3)

4.2 System Update Frequency

Automatic Updates:• XP: Automatic Updates is under System Properties

• Vista: Control Panel Security Windows Update

Other Software to Check:• Security software*

• Any 3rd Application under “Programs”

• Internet Browser Plug-ins:

Big Offenders: Sun, Adobe, Apple, Real

(Note: Demo after section 4.3)

4.3 Virtual Memory

Virtual Memory (sometimes called “Swap Space”) is a

method to give programs additional memory (or

sequential memory) after physical memory resources

have been exhausted.

Recommendations:

• Let the system manage the virtual memory, or

• Use minimum setting of double your physical RAM

Accessing Virtual Memory:Right Click “Computer” or “My Computer” select “Properties”

MSINFO32.EXE (Accessories System Tools)

System Information gives you a categorical overview of your

computer system, including drivers used and status of each.

http://support.microsoft.com/kb/308549

5.2 Device Manager

Device Manager provides an interface for viewing the configuration of

hardware devices. You can update the device drivers for hardware installed,

modify hardware settings, and troubleshoot problems.

5.3 HW Manufacturers Websites

The BEST place to find information about

a system, a component within that

system, or a driver is typically the

manufacturer.

Examples:

Maintenance Schedule

It is a good practice to physically clean your system once in a while,

and develop a schedule for routine cleaning. With software, you

can automate a lot of maintenance tasks. Physical maintenance

requires scheduled time.

To Physically Clean:

• Clean the outside components with dry or lightly damp cloth

(do not use chemicals, unless specifically specified for

computers)

• If you have components you no longer use, consider removing

them (for example, an old printer)

• For Desktops, open up and vacuum out the case and/or blow

out all dust. For Laptops, vacuum out all exhaust fans.
