Troubleshooting Windows problems and errors is difficult enough. But when the dreaded blue screen of death occurs, Windows adds to the frustration with it's default setting to automatically reboot Windows during System failures.
Fortunately, there is an easy fix to eliminate automatic restarts with Windows when an error or BSOD occurs.
Click on Start \ Run… (or press Windows key - Win+R) and type sysdm.cpl and click OK.
In System Properties window, click on the Advanced tab, then click on Settings button under Startup and Recovery.
NOTE: Screen shots are from Vista, and will be similar for Windows XP.
In Startup and Recovery window, uncheck Automatically restart under System failure section. Click OK to save setting (then click OK to close System Properties Window).
Now, if a System failure or BSOD (Blue Screen Of Death) occurs, you can easily write down the stop error code and other information…with out needing to reboot a hundred times to see the error message!
