Please remove Norton/Symantec. Norton tends to cause BSOD-s and causes several other issues. I would recommend uninstalling it with the Norton Removal Tool and replace with Microsoft Security Essentials
To Test. I have seen Trend Micro AV causing problems such as bsods on some systems, please uninstall this as well for testing purpose.
