What is Computer Maintenance?

Definition: Computer Maintenance
Computer Maintenance is basically the same as any other type of maintenance; it is a set of services or
procedures performed to keep something (in this case, a computer) in good working condition. A well-
maintained computer will run faster, more efficiently and crash less than one that has not been
maintained.


     Why Perform Computer Maintenance Procedures?
Maintaining your computer is not only good for your computer, but for you as well. Practicing good
maintenance procedures will save you money (less chance of items breaking down and having to
replace them), time (improved performance means less waiting time and less breaking down means
more usage) and protects your data (by backing up the data, for example).

Computer Maintenance Procedures
Quite a few things can be done to maintain your computer and you do not need to be a computer
technician in order to do so. Here is a list of some of the Computer Maintenance Procedures you can
do yourself:

1. Hard Drive Maintenance

2. Privacy Software

3. Updating Your Software




Hard Drive Maintenance
One of the most important components is your computer’s hard drive. On the hard drive all the
operating system’s files are stored along with programs and files of your data. Practicing good
hard drive maintenance will ensure your hard drive is fast, efficient and will last for years.
Hard Drive Maintenance Items
There are a few things that are part of hard drive maintenance that you can do. Things such as running
scandisk, disk defragmenter and hard drive storage are essential steps in maintaining your hard drive
and keeping it in peek condition

Scanning the Hard Drive
In order to scan the hard drive, you need to run Scan Disk. Scan Disk is a built in Windows
System Utility program used to check for errors in the hard drive. To do this in any Windows 95
and newer operating system, refer to the next section “Running Scan Disk”



What Does Scan Disk Do?
Scan Disk is used to check for errors on a hard disk. If Scan Disk finds errors, it will try to correct
these errors automatically. If there are problems with areas on the hard disk that Scan Disk
cannot fix, Scan Disk will mark them as “bad”, and Windows will not write to these bad areas on
the hard disk.

Errors on the hard disk can occur from improper Windows shutdown, programs ending
incorrectly (either through crashing or the power being turned off when the program was trying
to save) or just basic “wear and tear” of the hard drive.Running Scan Disk

    1. Double click on my computer on your desktop




                                                     My Computer

    2. Right click on the hard drive, and select “Properties”
                                    Accessing hard drive properties




3. In Windows XP, under “Tools”, select “Check Now…” under “Error-checking”
                                           Starting Scan Disk – Windows XP

4. In Windows XP, check off “Automatically fix file system errors” and “Scan for and attempt
   recovery of bad sectors”. Click “Start”




                                         Checking the hard disk – Windows XP




5. Windows XP will state that it will need to restart Windows and will run the check next time
   it starts up. Click “Yes” and restart Windows
                                Scheduling Scan Disk – Windows XP




6. In Windows 95/98/ME, under “Tools”, select “Check Now…” under “Error-checking
   status”
                                     Starting Scan Disk – Windows 95/98/ME

7. In Windows 95/98/ME, select the drive you wish to check, under “Type of test”, keep
   “Standard” selected unless you feel that you may have problems with the hard drive’s surface;
   if so, select “Thorough”. Check off “Automatically fix errors” and then click “Start”




                                         Scan Disk – Windows 95/98/ME

8. Scan Disk will take from 10 minutes to a few hours, depending on the type of test, amount of
   errors was in the hard drive and/or the size of the hard drive
    9. Once Scan Disk is finished in Windows 95/98/ME, there will be a brief summary of the results.
       Click “Close” to end Scan Disk




                                          Scan Disk results – Windows 95/98/ME




Defragmenting the Hard Drive
In order to defragment the hard drive, you need to run a Disk Defragmenter program. Disk
Defragmenter is a built in Windows System Utility program used to defragment the hard drive. To
do this in any Windows 95 and newer operating system, follow the steps outlined in “Running
Disk Defragmenter”



      Defragmenting the Hard Drive, a Warning
It is highly recommended that the power to the computer should not be turned off when running
Disk Defragmenter. Since Disk Defragmenter is copying and moving around files, shutting off
power to the computer can cause damage to your hard drive and possible data loss!


     What is Fragmentation?
Fragmentation refers to the condition of a disk in which files are divided into pieces scattered
around the disk. Windows will try to write the file contiguously, (basically meaning, all information
in a row, in the same area or in clusters on the hard disk), but sometimes the file is too large in
order to do so. So, Windows will store parts of a file in non-contiguous clusters. This is entirely
invisible to users, but it can slow down the speed at which data is accessed because the disk
drive must search through different parts of the disk to put together a single file.

It is recommended that you close all programs or applications, turn off your screen saver and let
Windows run Disk Defragmenter. Any other hard disk access will cause Disk Defragmenter to re-
read the drive information, therefore causing Disk Defragmenter to restart.
Running Disk Defragmenter
  1. Double click on my computer on your desktop




                                                  My Computer

  2. Right click on the hard drive, and select “Properties”




                                          Accessing hard drive properties
3. Now, select “Tools” and select “Defragment Now…”




                                     Accessing Defragmentation – Windows XP

       a. In Windows 95/98/ME, under “Defragmentation status”, it will tell you when the
          last time you have defragmented the drive. Click “Defragment Now…” to start
          Disk Defragmenter.




                                   Accessing Defragmentation – Windows 95/98/ME
4. Now in Windows XP, click on “Defragment”




                                      Starting Disk Defragmenter – Windows XP

5. Windows 95/98/ME, Disk Defragmenter should already be running




                                    Disk Defragmenter running – Windows 95/98/ME
6. Disk Defragmenter is now running. Depending on the size of your hard drive and/or how
   fragmented the drive was, it may take anywhere from 15 minutes to a few hours to be
   completed.




                                  Disk Defragmenter running – Windows XP
Privacy Software

What is Privacy Software?

Definition: Privacy Software
Privacy Software is software that ensures your privacy is maintained when you are on the Internet.
Many different programs that you use on your computer, from a web browser (i.e. Internet Explorer) to
Instant Messaging (MSN Messenger, Yahoo Messenger) keeps track of who you are, sites that you
have visited and other such information through cookies, browser history, username and password
storage and temporary files. Privacy Software ensured the deletion of these files and prevention of this
information being transferred to other sources.


     Why Use Privacy Software?
Using Privacy Software ensures the privacy of you and your information on your computer, but also
cleans up space, prevents the unauthorized installation of software (spy-ware, adware and dialers) and
frees up your Internet bandwidth.

Types of Privacy Software
There are many different kinds of privacy software out there, all claiming to protect you from hackers,
stop pop-ups and prevent spyware. Most of these programs add to the problem instead of fixing it
(since they contain spyware and adware). There is a program that I feel is one of the best programs
out there for privacy software, plus this program is free to download for personal use.

Spybot – Search & Destroy – http://www.safer-networking.org
Spybot – Search & Destroy can detect and remove spyware of different kinds from your computer.
Spyware is a relatively new kind of threat that common anti-virus applications do not yet cover. If you
see new toolbars in your Internet Explorer that you didn't intentionally install, if your browser crashes, or
if you browser start page has changed without your knowing, you most probably have spyware. But
even if you don't see anything, you may be infected, because more and more spyware is emerging that
is silently tracking your surfing behaviour to create a marketing profile of you that will be sold to
advertisement companies.

Spybot – Search & Destroy can detect and remove a multitude of adware files and modules
from your computer. Spybot also can clean program and Web-usage tracks from your system,
which is especially useful if you share your computer with other users. Spybot’s best feature
is “Immunize”, where as Spybot will create mock spyware and adware entries on you system to
“fool” the spyware and adware into thinking that it has already been installed, so it does not
install itself on the computer.Running Spybot – Search & Destroy

    1. First, go to http://www.safer-networking.org/en/download/index.html

Updating Windows
Keeping your software (Windows, anti-virus, etc.) up to date will ensure that the latest fixes and
updates are installed and available on your computer and your computer will run smoothly.
Updating your anti-virus software should be easy as clicking on a “Live-Update” button or visiting
the company’s web page of your anti-virus software. Steps to updating the software should be
contained in the website or in the documentation included with the software.

Why update Windows?
Updating your Windows operating system is very important. Microsoft puts out security fixes at a
rapid rate, since people will find problems with the operating system; but hats off to them for
addressing and fixing the problems.

Versions of Windows from 98 up contain a direct link to the Windows Update site on the start
menu, and Windows 2000 (with service pack 3) and XP have an automatic update feature which
will download the latest updates automatically.

Steps to Updating Windows


    1. Open up Internet Explorer and click on “Tools”“Windows Update”. If this is not
        working,     you    can    visit   Microsoft           Windows          Update   directly   at:
        http://windowsupdate.microsoft.com




                                      Accessing Windows Update in Internet Explorer
2. Or on Windows 98 and up, Windows Update can be accessed               through
