This behavior may occur if Windows stops responding during a typical operation or during the shutdown process. By default, the computer is configured to automatically restart when Windows stops responding. To view this setting, follow these steps:

1. Click the Start button, right-click My Computer, click Properties, click the Advanced tab, and then click Settings under Start up and Recovery.
2. Under System Failure, view the Automatically restart check box. If the Automatically restart check box is selected, Windows automatically restarts if the computer stops unexpectedly.

If your computer constantly restarts while you are using it, or if you are trying to shut down the computer after it has stopped unexpectedly, click to clear the Automatically restart check box. If you clear this check box, you receive an error message when the computer stops responding. This error message may describe the cause of the problem. You can also review the system log in Event Viewer to view the critical stop error that occurs when the computer restarts.

This seems like a conflict in the drivers. Check the device manager for conflicts like a yellow esclamation mark. YOu can get to it by going to start /control panel /system icon / device manager

Windows systems are notorious for crashing for any number of reasons and in a number of ways. Some of these crashes are mild and can easily be overcome simply by closing a nonresponding application or by rebooting the system. However, others are more serious and can bring the entire system to its knees. Microsoft calls these types of crashes "Stop errors" because the operating system stops responding. When a Stop error occurs, the GUI is replaced by a DOS-like blue screen with a cryptic error message followed by a code number. This screen is affectionately referred to as the Blue Screen Of Death.
what i mean, try to reformat in zero level of your HDD and install OS...
