There are no dump files attached, it's best to make sure that Windows has been configured to save Minidumps upon a BSOD:

• Dump Files - Configure Windows to Create on BSOD

Norton is a very heavy real-time protection program, and can cause BSODs in Windows 7.

Install and perform full scans with:

• Malwarebytes : Free anti-malware download
• Microsoft Security Essentials | Protect against viruses, spyware, and other malware

Remember to install the free version of Malwarebytes not the free trail; untick the free trial box during installation. MSE is the most lightweight and compatible with the Windows 7 operating system.
