I've gone an updated my system to reflect the changes I've made since I signed up on here.
I've tried the solutions in your signature but have the same result. One thing I've picked up on is that when I uninstall a program, any program the system will boot faster but subsequent boots cause it to return to the same slow boot pattern. My apologies for the late reply.
