I have a Dell Optiplex GX280 computer (Tag # 2KD0271) running XP Home, Service pack 2. I had the FBI virus on it and Dell could not solve my problem so I got it to boot and reloaded XP. No drivers showed up. I have a ? for all the items under Other Devices on the Device Manager page. I do have video and sound even though there is a ? on those devices. I have gone to Dell's site and downloaded the ethernet driver (R78500.exe) to a USB and loaded it but it does not show up on the computer as being loaded. What am I doing wrong. I have read several of the other posts and tried different things but nothing has helped. Please help I've been working on this problem for a week with no results.
