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 (see the following section, "Updating drivers").
Microsoft System Restore (see "Microsoft System Restore" on page 48) — Restores your computer
configuration to a configuration that was in use before the current software problem existed.
Software program and hardware driver reinstallation (See "Software program and hardware driver
reinstallation" on page 48) — Allows reinstallation of the factory-installed software or hardware driver
by using the Recovery Manager program.
System recovery (see "System Recovery" on page 49) — Erases and reformats the hard disk drive,
deleting all data files you have created, and then reinstalls the operating system, programs, and
drivers.
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.

new one does not solve your problem:
