We don't know, and the information you need to figure out the source of the problem is within your computer, Zemuron.
First, you need to look at the Event Viewer logs to see if information about the error is listed. These are located under the Control Panel Administrative Tools. The two important logs are Application and System. Any error can be right-clicked, and under Properties, additional information can be found.
To check and see if the problem is driver-related, or caused by a program loading when Windows starts, boot into Safe Mode. If there are no problems in Safe Mode, check the start up entries loading from the Registry by running MSCONFIG from the Start/Run command line. One of these might be the culprit.
If you want the computer to stop rebooting, you'll have to change this manually. This is done under Control Panel > System > Advanced > Startup and Recovery > Settings > System Failure. Kill the memory dumps, which are nearly always next-to-useless as a recovery tool, set the Write Information to none, and clear the check box for Automatically restart.
Be aware, though, that with this box cleared, any error that could halt the system is going to cause a blue screen, instead of rebooting. However, this might be the only way to see exactly what file, program, or driver is causing the problem. And if you take this route, complete documentation is necessary ... even the parts that don't make sense.
With this information at hand, you can start the process of troubleshooting the error. Much can be found on a error, simply by searching the error message and parameters at Google, especially when using the <A HREF="http://www.google.com/advanced_search?hl=en" target="_new">Advanced Search</A>, and specifying microsoft.com as the site or domain to be searched.
