A. I have an up to date virus checker (AVG 7 Pro) and that does not find any viruses, and I have done a virus check in safe mode, still no viruses.
"One" is not enough. Please read through this forum thread.
B. PART I:
1. The article [Q320299] explains that when you shut down your Windows XP-based computer, your computer may restart instead of shutting down and it may also restart unexpectedly while you are using the computer to perform certain tasks, which may occur if Windows is by default set to automatically restart when Windows stops responding and further explained in "How To Configure System Failure and Recovery Options in Windows (Q307973)."
2. It is reported in the article [Q873161] that after you install Microsoft Windows XP Service Pack 2 (SP2) and you are prompted to restart the computer, the computer starts, but before you can log on, the computer begins to continuously restart. This problem occurs if you had a UMAX scanner driver installed on your computer and the resolution is to start the computer in Safe Mode, remove the UMAX driver, remove Windows XP SP2, and then reinstall Windows XP SP2.
3. The article [Q316416] explains that when browsing the Internet, your computer may restart unexpectedly and can occur if both of the following conditions are true:
? A broadband cable modem or an asymmetric digital subscriber line (ADSL) modem is installed on your system, and the modem is using drivers that cause a fatal system (STOP) error.
Note: Depending on your system configuration, the resulting blue-screen error message may not be displayed long enough for you to record the error information.
? The Automatically restart check box is selected under System failure in the Startup and Recovery dialog box (under System Properties).
4. The article [Q308427] states that an "event" is any significant occurrence in the system or in a program that requires users to be notified or an entry be added to one of three logs that can help identify and diagnose the source of current system problems, or help predict potential system problems.
5. The article [Q314084] describes how to gather more information about an error message using Pstat.exe, a Resource Kit utility run from the command line that gives a picture of the processes and drivers that are currently running.
6. Access the Microsoft TechNet "Windows XP Events and Errors" page and enter the "Source" and "Error Code". -- the two most important items of information concerning an Event. When a reference is rendered, simply following the prompts for additonal information/help.
7. The article [Q307973] suggests that users configure the actions that Windows takes when a severe error (also called a fatal system error, or Stop error) occurs. Also, please read the article, "A Description of the Safe Mode Boot Options in Windows XP (Q315222)," for accessing a system that will not boot normally.
C. PART II:
The article [Q308538] describes Dr. Watson for the Windows program error debugger tool, which is a program error debugger that gathers information about your computer when an error (or user-mode fault) occurs with a program. When an error is detected, by default Dr. Watson creates a text file Drwrsn32.log that is saved in the following location:
drive:\Documents and Settings\All Users.WINNT\Application Data\Microsoft\Dr Watson
Note: The error reporting client for the operating system (DWWIN.exe (Dr. Watson)) can report errors in user mode, kernel mode, and unplanned shutdown events. In the event of a crash or assertion within an error reporting aware application, the application involved in the crash will call out the error reporting executable in a Just-in-Time fashion before the application closes down and then saves information such as the application name, application version, and a mini dump of the crash in a local log (such as MSInfo.log) which may be used for identifying the cause of the crash.
