BSOD was caused by ?

Event log shows Event ID 41, Task 63, .....Kernel Power.
I had no music players on, no videos, no scans.
Just surfing while protected in Sandboxie.
Other security is NIS 2010 and Prev 3 w/SafeOnline and Keyscrambler.
No other security or extra programs were running.
I have Windows 7 Pro x64, E8400 CPU and 4 G's RAM on a Gigabyte motherboard.

One thing I did notice is that Norton needed to do an update of virus signatures when I rebooted.
I scanned the pc with everything I have and found no problems.
What could have caused this and what do I do about it?
Thanks.
