You will need to go through the list of items that "startup" when the computer does and stop certain programs from "auto logon" , eg: going on line before Net Nanny is ready; programs like this include instant messengers, p2p file trading software and anti-virus "live updates".

Another good idea is to remove all advertising and spyware from your machine. There is a free program you can download from www.download.com called Ad-Aware. Install and run this on your computer to delete any spyware.

Spyware is advertising that's installed against your knowledge on your computer and that affects which advertisements you see when you're online. It can also affect the speed of your Internet connection and cause websites to re-direct.

Software is "competing" with the user to get online and causing the flickering back to NONE.
