Dang :banghead:.. I wish I can help you but I am banging my head here.. My last guess is the same as above.. Has to be when you go to a new website the
cpu power goes up to 100% and thats why get that lag. Zimbo might have somthing else to say, But I have looked everywhere, as Joe5 said they want you to pay for the drivers
You can go here and create an account and have them scan your pc they will at least tell you where you can get a free update for your drivers....
