I am running HP Pavilion a4310f, 3.0GHz, 6GB RAM, 640GB hard drive. I am observing the following difficulties: 1. No Internet connection 2. No audio 3. No System Restore 4. Modem, router seem to be functioning normally. I am able to sign in using this Asus netbook computer 5. Ran Norton Internet Security, Antispyware, Malwarebytes, CCleaner: no change 6. 'Network Hardware Not Recognized' 7. Microsoft installed automatic updates upon shutdown last night. 8. Same result with IE9, Firefox, Google Chrome. 9. All Win 7 network fixes failed or were inoperative. Is this a driver problem? If so, which ones am I missing? Difficult to obtain drivers since I cannot sign on to the Internet. I do have a peripheral DVD recorder to connect to this netbook if necessary to obtain Internet stuff. I must confess I never thought much of this netbook until now due to speed. Now it may be a lifesaver. As an aside, how does one access this website if not in possession of a second, functioning computer? Any help would be greatly appreciated.
