My system reboots from a bugcheck every time I run a virus check and close the antivirus program. I have tried 2 different virus programs AVG and Avast they both do the same thing. I have run chkdsk, defrag, memtest86, and reset the pagefile as per your instructions. The system allways reboots even though I have not selected to auto reboot in startup and recovery. The error I recieve is: Event Type: Information Event Source: Save Dump Event Category: None Event ID: 1001 Date: 10/13/2006 Time: 11:26:42 AM User: N/A Computer: ALW Description: The computer has rebooted from a bugcheck.
