First of all, McAfee makes the absolutely worst software in the world. I strongly urge you not to use it. BTW, what was wrong with Norton AV?
As for the bsod, you may have to do this from safe mode if you can't get to your desktop:
Download BlueScreenView:
http://www.nirsoft.net/utils/blue_screen_view.htmlunzip downloaded file and double click on BlueScreenView.exe to run the program.
when scanning is done, go to EDIT - Select All
Go to FILE - SAVE Selected Items, and save the report as BSOD.txt
Open BSOD.txt in Notepad, copy all of the content, and paste it into your next reply
