Microsoft told the customer that it was a device driver that caused the blue screen but they did not know which driver. I also see that the minidump file can be deciphered for that info. The event log description is. System Failure: Stop error Reason Code: 0x805000f Bug ID: Bugcheck String: 0x00000005 (0xf12fb1f8, 0xf8946020, 0x00000001, 0xf1513ac8) Comment: 0x00000005 (0xf12fb1f8, 0xf8946020, 0x00000001, 0xf1513ac8) Event Viewer System Error: Error code 00000005, parameter1 f12fb1f8, parameter2 f8946020, parameter3 00000001, parameter4 f1513ac8. Anyone know which driver it could be?
