Here are four methods that you can try to fix the problem or to determine what caused the problem. These methods are easy to follow. If one method does not resolve the problem or does not describe your situation, go to the next method.

Method 1: Determine whether the disc is causing the problem

Try to use several similar Xbox 360-compatible discs in the console to determine whether the disc that you are using is causing the problem. To test whether the problem is caused by a specific disc, use a disc of the same type, such as a game disc, DVD movie, or music CD. If the problem does not occur when you use other discs, that specific disc might be the cause of the problem.

For disc-specific issues, check the disc for any visible signs of damage or dirt. Hold the disc by the edges without touching the top or bottom surfaces with your fingers. Clean the disc by using a soft cloth. Lightly wipe from the center outwards. Do not use solvents or chemicals to clean the disc.

Method 2: Try installing the game on the Xbox 360 Hard Drive

If this problem occurs when you play one or more game discs, and if the Xbox 360 console has an Xbox 360 Hard Drive attached, try installing the game on the Hard Drive.

For more information about how to install an Xbox 360 game on an Xbox 360 Hard Drive, click the following article number to view the article in the Microsoft Knowledge Base:Note It may take 10 to 12 minutes to install a game on the Xbox 360 Hard Drive. If you have insufficient space on the Hard Drive to install the game, you can skip this method. However, this method helps troubleshoot the issue.

Method 3: Determine whether the game disc and the console are from the same country or region

Game discs and consoles are made for specific countries and regions. If you try to play a game disc that is made for a specific country or region on a console that is made for another country or region, the game disc will not play.

For example, if you purchase an Xbox 360 console in North America, your region is North America. Therefore, you cannot play game discs that are sold in Europe or in Asia on this console.

To see whether this issue occurs because the country or the region of the game disc and the console do not match, examine the back of the game package for one of the following codes:

•	NTSC: North America and South America (United States, Canada, Mexico, Chile, and Brazil)
•	NTSC-J: Asia (Hong Kong, Japan, Korea, Singapore, and Taiwan)
•	PAL: Europe, South Africa, India, Australia, and New Zealand

If your game disc code does not match the region where you bought the console, you cannot play the game disc.

Method 4: Determine whether the console is causing the problem

The problem might not involve the disc. Instead, the problem might be caused by your Xbox 360 console. To check this, follow these steps:

1.

If you have access to another Xbox 360 console, try to play the disc on the other console. Or, if the disc is a CD or a DVD, try to play the disc on another device, such as a CD player, a DVD player, or a computer that is equipped to play CDs or DVDs.

2.

If you have an Xbox 360 Hard Drive (HDD) or Memory Unit (MU) attached to the console, turn off the console, and remove the HDD and any attached MU. Then, turn on your console, and try the disc again. If this seems to resolve the problem, turn off your console, reattach the HDD and MU, and then delete any saved games for the game that is causing problems. Note If you can do this, save the games to a separate MU. If this does not resolve the issue but removing the Xbox 360 Hard Drive does, clear the Hard Drive cache.
