The antivirus you are currently using is known and contributing to your BSOD crashes, consider uninstalling it with the McAfee Removal Tool + ESET antivirus(with its removal tool because it contributes in crashes on some systems), replace with Microsoft Security Essentials at least to test and just FYI, keeping two antiviruses will be causing conflicts anyway.
You can however install ESET back if we know that it wasn't contributing in the BSODs, but I dare install Mcafee if it was my PC.
Reboot upon the system upon each removal or whenever asked to.
Recommended antivirus program for Windows 7 based on stability compared to others:-
:warn: 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.

These software can contribute in BSOD's. For drivers, prefer visiting the manufacturers website for latest drivers. 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.
Free up your start-up, keep nothing except the antivirus:
Run the System File Checker that scans the of all protected
Windows 7 system files and replaces incorrect corrupted, changed/modified, or damaged versions with the correct versions if possible:
Run Disk Check on your hard disk for file system errors and bad sectors on it:
