You can try to locate and close the software application that has stopped 
responding.

Press the Ctrl+Alt+Delete keys. The Windows Task Manager window 
appears.

From the Applications tab, locate the application that has the status message, 
“Not responding.”

Click to select the application and then click End Task. Windows attempts to 
close the application.

If your computer does not respond or the application does not close, try the 
following steps:

Save any open files, if possible.

Press the Alt+F4 keys. The Turn Off Computer window appears.

Click the Restart button.

If your computer still does not respond and you cannot restart, shut down your 
computer by pressing and holding the power switch for more than six seconds.

If the software application continues to be unresponsive or causes your computer 
to stop responding, contact the software publisher or designated technical support 
provider.

The Windows operating system may not shut down properly for many reasons, 
including incompatible or conflicting drivers, damaged files, or non-responsive 
hardware. For troubleshooting information, you can search Windows Help.

Click Start in the Windows taskbar and select VAIO Help and Support. The 
VAIO Help and Support dialog box appears.

Select Fixing a Problem and then select Startup and Shut Down problems. A 
list of specific problem topics appears on the right side of the dialog box.
