The computer does not detect the optical drive

If Windows does not detect an installed device, the device driver software may be missing or corrupted.
If you suspect that the optical drive is not being detected, verify that the optical drive is listed in the
Device Manager utility.
Remove any discs from the optical drive.
Click Start and type device manager in the Start Search box.
As you type, search results are listed in the pane above the box.
In the results pane, click Device Manager. If prompted by User Account Control, click Continue.
In the Device Manager window, click the plus sign (+) next to DVD/CD-ROM drives, unless a minus
sign (-) is already showing. Look for an optical drive listing.
If the drive is not listed, install (or reinstall) the device driver as instructed in the following section.

A disc does not play

Save your work and close all open programs before playing a CD or a DVD.
Log off the Internet before playing a CD or a DVD.
Be sure that you insert the disc properly.
Be sure that the disc is clean. If necessary, clean the disc with filtered water and a lint-free cloth.
Wipe from the center of the disc to the outer edge.
Check the disc for scratches. If you find scratches, treat the disc with an optical disc repair kit
available at many electronics stores.
Disable Sleep mode before playing the disc.
Do not initiate Hibernation or Sleep while playing a disc. Otherwise, you may see a warning
message asking if you want to continue. If this message is displayed, click No. After you click No,
the computer may behave in either of the following ways:
Playback may resume.
– or –
The playback window in the multimedia program may close. To return to playing the disc, click
the Play button in your multimedia program to restart the disc. In rare cases, you may need
to exit the program and then restart it.
Increase system resources:
Turn off external devices such as printers and scanners. Disconnecting these devices frees
up valuable system resources and results in better playback performance.
Change desktop color properties. Because the human eye cannot easily tell the difference
between colors beyond 16 bits, you should not notice any loss of color while watching a movie
if you lower system color properties to 16-bit color, as follows:
1. Right-click on a blank area of the computer desktop, and select Personalize > Display
