Some of the BSOD-s were caused by
Symantec Real Time Storage Protection. Would suggest you to remove Norton while troubleshooting (It's a frequent cause of BSOD-s.) Use Microsoft Security Essentials instead. (TO TEST)
Recommended antivirus program for Windows 7 based on stability compared to others:-

Run a full scan with both (separately) once downloaded, installed and updated.
System Optimisers
Please remove the following software
Code:
Start Menu\Programs\CleanMyPC Registry Cleaner Public:Start Menu\Programs\CleanMyPC Registry Cleaner Public
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 but make sure you back up the registry before making letting ccleaner delete anything.
