5Software 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.
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).
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.
34Chapter 5 Software Troubleshooting
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:
1.Close all open programs.
2.Click the Start button, right-click Computer, and then click Properties.
3.Click System protection.
4.Under Protection Settings, select the disk for which you want to create a restore point.
5.Click Create.
6.Follow the on-screen instructions.
For more information about software restore points:
1.Click the Start button, and then click Help and Support.
2.Type system restore into the Search box, and then press Enter.
Software Program and Hardware Driver Reinstallation
If an individual factory-installed software program or hardware driver is damaged, you can reinstall it
by using the Recovery Manager program (select models only).
NOTE:Do not use the Recovery Manager program to reinstall software programs that came on
CDs or DVDs included in the computer box. Reinstall these programs directly from the CDs or DVDs.
Before you uninstall a program, be sure you have a way to reinstall it. Check that it is still available
from where you initially installed it (for example, discs or the Internet). Or check that the program is in
the list of programs you can reinstall from the Recovery Manager.
To check the list of installable programs in the Recovery Manager:
1.Click the Start button, All Programs, Recovery Manager, and then click Recovery Manager. If

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.
