As a test, I would recommend uninstalling Norton and using Microsoft security essentials.

This software is a known cause of BSOD's. The windows 7 operating system does not require these registry cleaning software. They often tune-down rather than tune-up and can wreck the OS beyond repair. Microsoft have improved Windows 7 significantly and it is much better at organising and optimising itself than its predecessors. Check
this,
this and
this thread for evidence.
If you feel the need to use a registry cleaning or optimisation software, most of us recommend the use of
CCleaner - PC Optimization and Cleaning - Free Download but make sure you back up the registry before making letting ccleaner delete anything.
Perform a System File Check:
- Click on the start

- Type CMD on Search
- Left click and Run as Administrator
- Type SFC /scannow
