After reformating the hard drive, and used Sony's Recovery Disks to restore the computer - it is supposed to wipe out everything, then install all the software to the original condition as when I bought it. Well, not quite. The computer works, but can not access the internet. Found that the "Ethernet Controller Driver" was not installed. Went to Sony's website, they have all the software download for my computer except "Ethernet Controller Driver" - that's what I need. e-Mailed to Sony Computer support, they just don't answer, no reply no help at all. Googled and tried a lot of things but just couldn't get it to access the internet. Question: Where or how can I find that "Ethernet Controller Driver" for my Sony Vaio PCV-RX991 computer. (Ethernet Controller Driver problem seems to be wide spread with different Sony computers.) Appreciate very much for your help. I have several computers. This is an old one. Plan to restore it to the original condition and will be given to my grand-children, aged 5 and 8 to play with. If anyone can help to get it to work, I will be happy to treat you a nice dinner. I googled and tried to download the said driver from CNET Download.com, not only it did not help me but also almost ruined my working computer - dangerous to access that site. I have spent a week to google to find a solution to no avail. One interesting user comment on another site said: "Ethernet Controller" is not a device, it is just a useless description of a problem by Windows XP. I don't have any knowledge to tell if that is true or not. After reformatting, lots of Sony Vaio computers are unable to access the internet - you can even see that on this site.
