6 Software Troubleshooting

Your computer uses the operating system and installed software programs during normal operation. If
your computer works improperly or stops because of the software, you may be able to repair it.

Some software repairs are as simple as restarting your computer, and others require performing a
system recovery from files on your hard disk drive.

Software Repair Overview

The most efficient way to repair software problems is simply to restart the computer or turn the computer
off completely and then power it back up again. If this does not work, then explore the following
methods for fixing your computer if you are experiencing software problems:

●

Updating Drivers

●

Microsoft System Restore

●

Software Program and Hardware Driver Reinstallation

●

System Recovery

Updating Drivers

A driver is a software program that enables your computer to communicate with an attached device,
such as a printer, hard disk drive, mouse, or 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 the Start button.

2. Type Device Manager into the Start Search box, and then click Device Manager to open the

Device Manager window.

3. Click the plus sign (+) to expand the type of device for which you want to update or rollback, (for

example, DVD/CD-ROM drives).

4. Double-click the specific item (for example, HP DVD Writer 640b).

56 Chapter 6 Software Troubleshooting

5.

Click the Driver tab.

6.

To update a driver, click Update Driver, and follow the on-screen instructions.

– or –

To revert to an earlier version of a driver, click Rollback Driver, and follow the on-screen
instructions.

Microsoft System Restore

Microsoft Windows 7 includes a feature that enables you to restore your computer configuration to a
configuration that was in use before the current software problem existed. The feature does this by
creating a restore point where it records the computer settings at that time and date.

When a new program is installed, the operating system automatically creates a restore point before it
adds the new software. You can also set restore points manually.

If you experience a problem that you think may be due to software on your computer, use System
Restore to return the computer to a previous restore point.

NOTE: Always use this System Restore procedure before you use the system recovery program.

To start a System Restore:

1. Close all open programs.

2. Click the Start button, right-click Computer, and then click Properties.

3. Choose System protection, System Restore, and then click Next.

4. Follow the on-screen instructions.

To manually add restore points:

Creating data backup discs

Use CD or DVD recording (or burning) software that is installed on your computer to create backup
discs of important information, including personal files, e-mail messages, and Web site bookmarks. You
can also move data to an external hard disk drive.

When writing data to a backup disc, use software that includes write verification functionality. This
feature compares the data on your hard disk drive with the data copied to the disc to ensure it is an
exact copy. Depending on your disc recording software, you may need to manually enable this feature
(refer to the software documentation).

If you encounter recording issues, try alternate media (different types or brands). Also, use the
Windows Explorer tool to view your files and verify content was copied over. To open Windows
Explorer, right-click the Start button, and then click Explore.

Clearing CMOS

When the BIOS has been incorrectly configured, it is sometimes necessary to clear all CMOS settings.

To clear the CMOS, users need to perform the following steps:

CAUTION: Before attempting to remove or touch any parts from the motherboard, check that the

power cord is disconnected from the electrical outlet. Failing to do so can cause hardware damage
and even physical injury.

1. Shut down the operating system and turn off the computer and any external devices.

2.

Disconnect the power cords of the computer and any external devices from the power outlet.

3. Disconnect any external devices that are connected to the computer.

4. Remove the chassis cover.

5.

Locate the CMOS jumper header on the motherboard.

CAUTION: Removing the incorrect jumper can cause the system configuration to be changed or

even cause irreparable hardware damage.

6. Set the jumper to cover the middle and third pins for at least five seconds.

7. Set the jumper back in its original position.

8. Replace the hood cover.

9. Reconnect the external equipment.

10.

Plug in the computer and turn on the power. Allow the operating system to start.

Clearing BIOS passwords

If a user has configured a power-on or setup password using the BIOS and then loses the password,
they cannot access the BIOS in order to change or clear the password.

In this event, to clear the power-on or setup passwords—or to disable the power-on or setup password
feature—users need to perform the following steps:

CAUTION: Before attempting to remove or touch any parts from the motherboard, check that the

power cord is disconnected from the electrical outlet. Failing to do so can cause hardware damage
and even physical injury.

1. Shut down the operating system and turn off the computer and any external devices.

2. Disconnect the power cords of the computer and any external devices from the power outlet.

3. Disconnect any external devices that are connected to the computer.

4. Remove the chassis cover.

5.

Locate the BIOS password jumper header on the motherboard.

CAUTION: Removing the incorrect jumper can cause the system configuration to be changed or

even cause irreparable hardware damage.

6. Move the jumper to cover the middle and third pins for at least five seconds. This clears the current

passwords.

7. Replace the jumpers in their default positions.

8. Replace the chassis cover.

9. Reconnect the external equipment.

Power-On Self Test (POST)

When the system is turned on, all installed components are tested to verify that they are working
properly. This series of tests is called the Power-On Self-Test.

The POST runs basic tests on the following system components:

●

Installed hardware

●

Memory

●

Cache

●

PCI data path

●

Flash ROM

7System Recovery

System recovery completely erases and reformats the hard disk drive, deleting all data files you have
created. System recovery reinstalls the operating system, programs, and drivers. However, you must
reinstall any software that was not installed on the computer at the factory. This includes software that
came on CDs included in the computer accessory box, and software programs you installed after
purchase.

You must choose from the following methods for performing a System Recovery:

Recovery Image—Run the system recovery from a recovery image stored on your hard disk drive.
The recovery image is a file that contains a copy of the original factory-shipped software. To perform a
system recovery from the recovery image on your 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 system recovery from a set of recovery discs that you create from files
stored on your hard disk drive.

Creating Recovery Discs

Complete the procedure described in this section to create a set of 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 computer at the factory.

You can create only one set of recovery discs for your computer. Furthermore, the recovery discs you
create can be used only with your computer.

Choosing Recovery Discs

To create recovery discs, your computer must have a DVD writer.

●

Use DVD+R or DVD-R blank media to create your system recovery discs.

●

You cannot use DVD+RW, DVD-RW, DVD+RW DL, DVD-RW DL, DVD+R DL, DVD-R DL, or CD
discs to create recovery discs.

Use high-quality discs to create your set of recovery discs. The verification standard for the recovery
disc creation process is very high. You may see error messages such as Recording failure when writing
disc or Error detected during disc verification.

Creating Recovery Discs

63

Your discs may be rejected if they are not defect-free. You will be prompted to insert a new blank disc
to try again. It is normal that some of your discs may be rejected.

The number of discs in the recovery disc set depends on your computer model (typically 1–3 DVD
discs). The Recovery Disc Creator program tells you the specific number of blank discs needed to make
the set.

The process takes some time 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 resumes where it left off.
