Recovering From Software Problems
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.
The Software Repair Wizard (select models
only) is an icon on the desktop or in the
Organize software program, or in the Help
and Support Center. To start the wizard, click
the icon or click Start, choose All
Programs, PC Help & Tools, and then
click Software Repair Wizard.
Click the Software Repair Wizard icon to repair software
problems with programs, printers, or peripherals that stop
working, or to resolve erratic PC behavior. Repair options
include using the Compaq Application Recovery or Compaq
System Recovery programs.
You need recovery discs (CDs or DVDs) for some repairs that
use the Compaq Application Recovery program or the
Compaq System Recovery program. The PC does not
include recovery discs in the accessory box, but you can
make your own recovery CDs or DVDs; see “Creating
Recovery CDs/DVDs.”
CAUTION: It is strongly recommended that you
create your recovery discs before you need
them.
You should also make the Compaq Recovery Tools CD. This
CD contains utilities that allow you to make changes to your
hard disk drive, including removing the recovery partition.
See “Using the Recovery Tools CD.”
There are several methods to fix your PC, including using the
System Recovery program. Try these methods in the order
listed here, or refer to the table that follows the list.
•
Restart When you restart the computer, the PC starts
over using the operating system and software in its
memory. This is the simplest repair for your PC; just click
Start, choose Turn Off Computer, and then click
Restart.
•
Turn Off Computer When you turn off the computer
and then turn it on again, you force the PC to copy the
operating system into its memory and to clear some
tracking information. This may eliminate some problems
that can remain after performing a Restart. To turn off the
computer just click Start, choose Turn Off Computer,
and then click Turn Off.
•
Driver Rollback This Microsoft Windows XP feature
is part of the Windows Installer program used with the
Add or Remove Programs utility in the Control Panel. It
can revert to the previous version of a driver program if
an installation fails when you are installing a new version
of the driver program. For more information, type
Rollback into the Search box in Help and Support.
