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.

your computer to the state that existed before you installed the new driver.
