Installing Drivers for Media Drives
A driver is a program that controls your media drive. You may need to install
drivers if you:
• Upgrade your operating system.
• Reinstall your operating system.
• Connect or install a new device.
Determining Whether a Device Driver is the Source of a Device Problem
1 Click Start and right-click Computer.
2 Click Properties→ Device Manager.
3 If a window appears asking permission to continue, click Continue.
4 Scroll down the list to see if any device has an exclamation point (a yellow
circle with a [!]) on the device icon.
If an exclamation point is next to the device name, you may need to
reinstall or update the driver.
Replacing a Driver With a Previous Version of the Driver
If a problem occurs on your computer after you install or update a driver, use
Windows Device Driver Rollback.
1 Click Start and right-click Computer.
2 Click Properties→ Device Manager.
3 Right-click the device for which the new driver was installed, and click
Properties.
4 Click the Drivers tab→ Roll Back Driver.
If Device Driver Rollback does not resolve the problem, use System Restore
(see "Using Microsoft
®
Windows
®
System Restore" on page 265) to return
your computer to the state that existed before you installed the new driver.
