I'm trying to fix a laptop I have it would not connect to the internet no matter if i tried ethernet, usb, or wireless. Also I could not get the sound to work. I tried to reinstall drivers for modem, and sound from the HP website and I just could not seem to fix the problem. I saved all my pictures and music and reformatted the comp and figured this would fix it. Since the reformat I still can not connect to the internet and I still can't get sound to work. I'm trying to think this is a software issue as much as I can to avoid it being hardware. Also in device manage what is this Base System Device? I've installed all the drivers off HP's website.. and no luck. When I open the internet browser it just says can not connect I don't know what to do from here. Any help muchly apprectiated!
