To repair software problems, try these methods:
●
Turn the computer off completely, and then turn it on again. Sometimes this is the easiest way to fix a
problem.
●
Update the drivers (see Updating drivers on page 20).
●
Use Microsoft System Restore (see Microsoft System Restore on page 21) — Restore your computer to a
configuration that was in use before the software was installed.
●
Reinstall the software program or hardware driver. (See Software program and hardware driver reinstallation
on page 21) — Restores the software (if it came with the product) or hardware driver to factory defaults.
●
System Recovery (see System Recovery on page 24) — Erase and reformat the hard disk drive, and then
reinstall the operating system, programs, and drivers.
CAUTION:
This erases all data files you have created.
