Your one .dmp file was inconclusive. It is difficult to find patterns and determine causes of crashes with only one .dmp file. We may need to wait for more. If you had more .dmps, you may have deleted them by running CCleaner. Please refrain from using CCleaner for the duration of our troubleshooting.

I did note that you have Norton Internet Security and AVG installed. Choose one or the other. Having two security programs that accomplish identical tasks can cause instability due to the two programs simultaneously accessing system files or system resources.
