Well the problem is McAfee itself, as far as I can say(for some reason). It very often causes BSOD-s on the system. You consider uninstalling it with the McAfee Removal Tool and replace with Microsoft Security Essentials at least to test.
(Please uninstall Ad-Aware - if you have it and spybot S&D slows down the system, please uninstall it as well). Uninstall using the free version of Revo Uninstaller [Advanced Mode]
Recommended antivirus program for Windows 7 based on stability compared to others:-
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.

Simple stuff:
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:
Free up the start-up, nothing except the antivirus is usually needed.

Install all windows updates, including Service Pack 1
Look for a newer version on the BIOS:
