Welcome to SevenForums.

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)

• Norton Removal Tool

Recommended antivirus program for Windows 7 based on stability compared to others:-

• Microsoft Security Essentials - Free Antivirus for Windows
• Microsoft Security Essentials Download | Free Spyware Protection
• Malwarebytes - The Free version
• Good and Free system security combination.

Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

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.
