Repairing Software
Problems
NOTE: If you are replacing a hard disk drive, you
only have to run the System Recovery.
The PC uses the operating system and installed
software programs during normal operation. If
your PC works improperly or stops because of the
software, you may be able to repair it.
Some software repairs are as simple as restarting
your PC, and others require performing a System
Recovery from files on your hard disk drive.
Your hard disk drive contains a System Recovery
image that includes all the software files that were
originally installed on your PC at the factory. In the
unlikely event that you need to recover your system,
it is easy to do so using this recovery image.
Since all the necessary information is contained in
the System Recovery image on your hard disk drive,
recovery discs are not included in the accessory box.
As a backup, you can make your own copy of this
system recovery image onto CD or DVD discs as
described in “Creating System Recovery Discs“ later
in this document.
You should also make a Compaq Recovery Tools CD.
This CD contains utilities that allow you to make
changes to your hard disk drive. See “Creating a
Recovery Tools CD“ for more information.
Additionally, your PC may include a Software
Repair Wizard (select models only). You can
use this wizard to access many of the repair
methods described in this chapter, including:
• Creating System Recovery discs
• Microsoft System Restore
• Application Recovery and Driver Recovery
• System Recovery
You can start the Software Repair Wizard by clicking
Start, All Programs, PC Help & Tools, and then
Software Repair Wizard.

PC Troubleshooting Guide 1
Updating Drivers
W
A driver is a software program that allows your PC to
communicate with an attached device, such as a
printer, a hard disk drive, a mouse, or a keyboard.
Complete the following procedure to update a driver,
or to revert to an earlier version of the driver if the
new one does not solve your problem.
1 Click Start, right-click on My Computer, and
then click Properties. The System Properties
window displays.
2 Click the Hardware tab, and then Device
Manager. The Device Manager displays.

follow the onscreen instructions.
Microsoft System Restore
Microsoft® Windows® XP includes a feature that allows
you to restore your PC configuration to that of a
previous time when a current software problem did
not exist. The feature does this by creating a “restore
point” where it records the PC settings at that time
and date.
When you add programs by clicking Add New
Programs in the Add or Remove Programs window
(accessed by clicking Start, Control Panel, and
then Add or Remove Programs), the operating
system automatically creates a restore point before it
adds the new software. You can also set them
manually.
If you experience a problem that you think may be
due to software on your computer, use System Restore
to return the PC to a previous restore point.
ARNING: Always use this System Restore
procedure before using the Compaq PC
System Recovery program.

System Recovery Overview
After you have tried the previously mentioned methods
of repairing your system software, you can run the
System Recovery program as a last resort to reinstall
the operating system and the application software.
System recovery provides two recovery options:
• Standard Recovery — This option recovers
factory-shipped programs, drivers, and the
operating system without affecting any data files
that you may have created since purchasing this
PC. Some data files may be difficult to find after the
System Recovery, so it is best to back up all hard
disk drive files before performing a System
Recovery.
• Full System Recovery — This option completely
erases and reformats the hard disk drive — this
includes deleting all data files you have created.
The full System Recovery reinstalls the operating
system, programs, and drivers from the recovery
image or discs. However, you must reinstall any
software that was not installed on the PC at the
factory. This includes software that came on CDs
included in the PC accessory box, and software
programs you installed since your purchase.
NOTE: If your PC has a blank or corrupted hard disk
drive, you will see only the full System Recovery
option.
NOTE: If your PC includes an HP Personal Media
Drive (select models only), you must remove it before
starting the System Recovery program.
Additionally, you have to choose from the following
methods for performing a system recovery:
• Recovery Image — Run the recovery from a
recovery image stored on your hard disk drive. The
recovery image is a file that contains a copy of the
original software. To perform a system recovery
from the recovery image on your hard disk drive,
see “Running System Recovery from the Hard Disk
Drive.”
NOTE: The recovery image uses a portion of the
hard disk drive that cannot be used for data
storage.
• Recovery Discs — Run the recovery from a set of
recovery discs (CDs or DVDs) that you create from
files stored on your hard disk drive. To create
recovery discs, perform the procedure in the next
section.
PC Troubleshooting Guide 3
Creating System Recovery Discs
Complete the procedure described in this section to
create a set of system recovery discs from the recovery
image stored on your hard disk drive. This image
contains the operating system and software program
files that were originally installed on your PC at the
factory.
You can only use one set of recovery discs for your
PC. The recovery discs you create can only be used
with your PC.
After creating the recovery discs, you can delete the
recovery image if you would like to make extra space
available on your hard disk drive.
NOTE: Do not delete the recovery image unless you
have made recovery CDs or DVDs.
Choosing recovery disc media
There are several advantages to using DVDs instead
of CDs when creating recovery discs:
• DVDs have a faster data transfer rate. DVD
recovery discs restore the original data faster than
CD recovery discs.
• DVD recovery discs take less time to create than CD
recovery discs.
• DVDs have greater capacity than CDs, so there are
fewer discs to record and store.
To create recovery discs, your PC must have a CD or
DVD Write drive, or other drive that can write to CDs
or DVDs.
The number of discs in the recovery disc set depends
on your PC model. The program that creates the discs
tells you the number of blank discs needed to make
the set. The process takes some time, including up to
15 minutes per disc, to verify that the information
written on the disc is correct.
You can quit the process at any time. The next time
you run the program, it begins where you left off.
To create System Recovery discs:
1 Close all open programs.
2 Click Start.
3 Choose All Programs.
4 Choose PC Help & Tools.
5 Click Compaq Recovery CD-DVD Creator.
The Recovery CD/DVD Creator window appears.
6 Follow the onscreen instructions. Label each disc as
you make it (for example, Recovery 1, Recovery 2).
Store the System Recovery discs in a safe place.
Creating a Recovery Tools CD
In addition to system recovery discs, you can create a
Recovery Tools CD. The Recovery Tools CD can be
used to:
• Read instructions to use each utility on the Recovery
Tools CD.
• Start the System Recovery program from the
recovery partition.
• Remove the System Recovery partition from your PC
hard disk drive to increase space for data.
• Create a new data partition on your PC hard disk
drive.
• Start the Microsoft Recovery Console (a utility from
Microsoft that can perform operating system
diagnostics and repairs).
WARNING: Before using the Compaq
Recovery Tools CD to change your hard
disk drive, create System Recovery discs as
described in the previous section. You
cannot make System Recovery discs after
you remove the System Recovery partition.
You must create a Recovery Tools CD before you can
use any of these utilities.
To create or start the Recovery Tools CD:
1 Click Start.
2 Choose All Programs.
3 Choose PC Help & Tools.
4 Click Compaq Recovery Tools CD. The tools
window appears.
5 Follow the onscreen instructions.
Store the Recovery Tools CD in a safe place.
4 PC Troubleshooting Guide

Hard Disk Drive Space
Compaq Presario desktop PCs with the Windows XP
operating system preinstalled may appear to have a
hard disk drive smaller than what is stated in the
product specifications, documentation, or on the box.
Hard drives are described and advertised by
manufacturers in terms of decimal (base 10) capacity.
Windows and other programs, such as FDISK, use the
binary (base 2) numbering system.
In decimal notation, one megabyte (MB) is equal to
1,000,000 bytes, and one gigabyte (GB) is equal to
1,000,000,000 bytes. In the binary numbering
system, one megabyte is equal to 1,048,576 bytes,
and one gigabyte is equal to 1,073,741,824 bytes.
Because of the different measuring systems, you may
see a difference between the size reported by
Windows, and the size advertised. The storage
capacity of the hard disk drive is as advertised.
Windows reports smaller capacity in the Windows
Explorer tool and in the My Computer window
because it only shows information about one partition
on the hard disk drive at a time. The first partition
contains the System Recovery information.
