Hi Steve,
Suggestions:
By default when WinXP encounters a system failure, it reboots without
warning. The setting that controls this can be changed:
Control Panel/System/Advanced/Settings (Startup & Recovery)/System
Failure/Uncheck-Automatically Restart.
You can use Event Viewer to view and manage the event logs, gather
information about hardware and software problems, and monitor Windows
security events.
To view the event log: Administrative Tools/Event Viewer or
Start/Run/eventvwr.
To review Shutdown Event Tracker data, Open Event Viewer. Click System Log,
scroll to the Event column, and find entries with the number 1075.
