I have a computer with Windows XP Professional SP3, Intel Pentium Dual CPU E2200 processor and 2 GB RAM. About 3 days ago, it rebooted while I was working on it. Today, it rebooted again. Both times, there was an event numbered 1001 in the Event Viewer (eventvwr), whose source was "Save Dump". In the first reboot, the event 1001 had the following description: In the second reboot, the event 1001 had the following description: Both times, the 1001 "Save Dump" event was also followed by a 1003 event, whose source was "System Error", and whose description was (for the first and second reboots, respectively): I've attached the memory dumps of both reboots here, in a ZIP archive. Could someone analyze them, to discover what caused the problem? Any help would be appreciated.
