●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 before playing the disc.

Do not initiate Hibernation or Sleep while playing a disc. Otherwise, you might see a warning message asking if you want to continue. If this message appears, click No. After clicking No, the computer might:

1.Right-clicking on a blank area of the computer desktop, and selecting Screen resolution.

2.Selecting Advanced Settings > Monitor tab.

3.Selecting High Color (16 bit), if this setting is not already selected.
