Repairing Software Problems 23

Repairing Software Problems

Your computer uses the operating system and installed

software programs during normal operation. If your

computer works improperly or stops, you may be able

to repair it.

Restarting Your Computer

Restarting is the simplest repair method for your

computer. When you restart, the computer reloads the

operating system and software into its memory.

To restart your computer:

1 Close all open programs and windows.

2 Click the Windows Start

Button, click the Arrow button

next to the Lock button, and then

click Restart.

Turning Off Your Computer

When you turn off your computer and then turn it on

again, you force the computer to reload the operating

system into its memory, which clears some tracking

information. This may eliminate some problems that

can remain after you perform a restart.

To turn off your computer:

1 Close all open programs and windows.

2 Click the Windows Start

Button, click the Arrow button

next to the Lock button, and then

click Shut Down.

3 Start your computer by pressing the On button.

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 (or roll back) to an earlier version of the

driver if the new one does not solve your problem:

1 Click the Windows Start Button, right-click

Computer, and then click Properties.

2 Under Tasks, click Device Manager.

3 Click the plus sign (+) to expand the type of device

for which you want to update or roll back the

driver, (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

then follow the onscreen instructions.

To revert to an earlier version of a driver, click

Rollback Driver, and then follow the onscreen

instructions.
