I just had a stop error. The system restarted on its own. I found in the system event viewer the following errors: 11/16/2010 4:53:50 system error (102) 1003 N/A computerName 11/16/2010 4:55:53 DCOM None 10010 SYSTEM computerName I included the mini-dump for this. Mini111610-01.dmp The only time I've had a stop error in the past was two weeks ago. I got new speakers, simple ones - no software included, and just plugged them in. A few minutes later the system hit a stop error and restarted. I've included that mini-dump. Mini110210-01.dmp Between these two instances I see the following errors in the log: system control manager 7000 system control manager 7009 browser 8032 (2) DCOM 10010 The only strange thing I'm doing - besides brazenly switching speakers - is running Virtual Box. Can anyone give me an idea what's going on?
