Step 1

Figure out which driver version you currently have. On a Windows computer, right-click My Computer and click Properties; select the Device Manager tab. Click the plus sign to the left of a specific device to find the drivers that are currently installed for it. On a Macintosh, use the Apple System Profiler program to check driver versions. (If the Profiler doesn't list a device, check the Extensions Manager control panel.)

Step 2

Find out whether a newer driver exists by visiting the Web site for the manufacturer of your device. A newer driver will have a later creation date than the one you have.

Step 3

Follow instructions to download a newer driver.

Step 4

Make sure you have the original drivers. If there are problems with the new driver, you want to be able to restore the old one.

Step 5

Double-click the icon for the downloaded driver.

Step 6

Follow installation instructions that appear. Look for a file named readme.txt or readme.doc.

Step 7

If the installation didn't remove the old driver, remove it. On a Windows computer, right-click the driver in the Device Manager and select Remove. On a Macintosh, drag the old driver file out of the Extensions folder in your System Folder, and either save it elsewhere or delete it.

Step 8

Restart the computer.
