Sound like an error is occuring on shutdown that's causing a restart - Right click on COMPUTER, select PROPRTIES, ADVANCED SYSTEM SETTINGS and under STARTUP and RECOVERY select SETTINGS. untick automatically restart. That should allow you to see the error. Also look in the event log. The event viewer is in Control Panel-&gt;Administrative Tools-&gt;Event Viewer-&gt;Windows Logs-&gt;System Log

Computer Automatically Restarts After Shutdown

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.

Windows Vista is an operating system created by Microsoft as the successor to Windows XP. It was intended for PCs, workstations and laptops, and shares the same code base as its successor, Windows 7. New features included an updated graphical user interface (GUI) and visual style dubbed Aero, a new search component called Windows Search, redesigned networking, audio, print and display subsystems, and new multimedia tools. Vista aimed to increase the level of communication between machines on a home network, using peer-to-peer technology to simplify sharing files and media between computers and devices. Windows Vista included version 3.0 of the .NET Framework, allowing software developers to write applications without traditional Windows APIs.
