Around four days ago i upgraded windows vista home premium to windows 7 home premium. In windows vista, whenever i would be online for more than a while, internet explorer would frequently stop working all of a sudden and didn't respond to any commands, forcing me to shut the computer down completely. I upgraded for that main reason in the hopes the internet would work near flawless. So now I am having the same problem as i did in windows vista, the internet just STOPS WORKING and it becomes so annoying since i have much work to get to online! Any ideas why the internet would stop working all of a sudden?
