Recovering From Software Problems
The HP Digital Entertainment Center (HP DEC) uses the
operating system and installed software programs during
normal operation. If your HP DEC works improperly or stops
because of the software, you may be able to repair it.
For some software repairs, use the HP Application Recovery
program or the HP PC System Recovery program. These
programs use the recovery DVD disc included in the
accessory box.
There are several methods to fix your HP DEC. Try these
methods in the order listed here, or refer to the table that
follows the list:
•
Restart When you restart the HP DEC, the computer
starts over using the operating system and software in its
memory. This is the simplest repair for your computer; just
click Start, choose Turn Off Computer, and then click
Restart.
•
Turn Off Computer When you turn off the HP DEC
and then turn it on again, you force the computer 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.
•
System Restore This Microsoft Windows XP feature
allows you to bring your HP DEC configuration back to a
previous time when a current software problem may have
not existed. The feature does this by creating a ”restore
point” where it records the computer settings at that time
and date. The installation of some software automatically
sets a restore point for you, but it is recommended to
manually set restore points, especially before installing or
downloading additional software. When using Add
Programs from the Add or Remove Programs feature
under the computer Control Panel, the operating system
automatically creates a restore point before it adds the
software. 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. For more
information, type System Restore into the Search box in
Help and Support.
•
Application and Driver Recovery If the problem
with the HP DEC seems to be with only one program or
one driver, it may be that the application program or the
driver program is damaged. You can reinstall individual
factory-installed application programs and driver
programs by using the HP Application Recovery
program (select models only); see ”Application
Recovery” on page 5.
•
System Recovery Use the HP PC System Recovery
program as a last resort to reinstall the software. First
perform System Recovery using the recovery discs and
choose Standard Recovery. Finally, if necessary, perform
System Recovery using the recovery discs and choose full
System Recovery. Refer to ”System Recovery Using
Recovery Discs” on page 6.
Before using the HP PC System Recovery program or the
HP Application Recovery program, use System Restore.
When your HP DEC stops working correctly, the Restart, Turn
Off Computer, and Driver Rollback methods (described
above) may resolve the problem. After you have tried these
three methods, if needed, try the remaining actions, using
the table that follows as a quick reference.
