My bru i`m not to sure when you mean windows start button,do you mean the explorer on my desktop which allows me to get onto the internet.
I`ll give you a run down on what could of maybe happened a guy said i should download google firefox instead of using my original explorer.So i made it my default browser then i had a few errors occur so i replaced my explorer browser and uninstalled firefox.Could this have an effect on what is going on now,could you please if you know what to do explain to me in simple terms what i can do to fix the problem. Thanks in advance.
