    I HAVE ALSO WINDOWS DOES NOT WHEN I AM OFFLINE AND TRY TO CLOSE AFTER HAVING PLAYED A FEW GAMES INSTALLED FACTORY.  I USE A WINDOWS VISTA WITH A HP PC.  IT COULD BE RELATED?

    Hello

    1. did you of recent changes on the computer?

    2. you receive an error message?

    3 when was the last time it was working fine?

    Method 1

    It is possible that some third-party programs installed on the computer is causing the problem.

    I suggest that you perform a clean boot and check.

    To help resolve the error and other messages, you can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See the link below to learn more about how to clean boot.

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

    http://support.Microsoft.com/kb/929135

    Reset the computer to start as usual

    When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

    (a) click Start, type msconfig in the search box and press ENTER.

    (b) If you are prompted for an administrator password or for confirmation, type your password or click on continue.

    (c) under the general tab, click the Normal startup option, and then click OK.

    (d) when you are prompted to restart the computer, click on restart.

    Method 2

    If the above step failsthenI suggests Mr scanner SFC on the computer that would scan for corrupt system files on the computer and replace them.

    The analysis may take some time, so be patient. Windows allows to fix corrupt or missing files it finds. If the information of the installation CD is required to fix the problem, you may be asked to insert your Windows Vista installation CD.
