If you have activated resident parts of all those 3 programs that could create problems. You should use only 1 resident AV/Antispyware program, can supplement with 10 others as long as they dont conflict.
At least for troubleshooting purposes get rid of one. You can ask Norton Support site or forum which to delete, or you can go to Avast site, see Knowledgebase about "avast! and other antivirus applications"
If you decide to say goodbye to Norton then notice their tool for removal http://service1.symantec.com/SUPPORT/tsgen...005033108162039
I would run that after doing manual uninstall.
Dont know what type of Norton package you have but they dont recommend using Windows Defender and Windows Firewall if they have simular stuff installed. If you install new NIS 2009 it automatically disable both. Only disable Windows Firewall if there is another to replace of course.
Untick "Autmatically restart" in Control Panel, System, Advanced system settings, Startup and Recovery. That way Windows might give a hint as to what trigger crash.
Other drivers you have updated according to Gateways advice for your model?, also the perhaps many extra utilities they install? Be a sheep and install exactly what they suggest.
Not sure how you have ruled out hardware - return to that if crashes continues. If you have to get in contact with Gateway then probably easier if you have done everything by the book. 2 AVs is like the opposite
