Hello, My network controller and drivers will not install. I have a dell dimension C521 and will the drivers from dells support site my computer will not install them. I feel like it may be some kind of physical failure on the motherboard, but if there is a chance i can fix it, im open to anything. one thing is for sure ive never had this much trouble with drivers on a fresh windows xp install. i may just install windows 7 to see if network is still AWOL. like i say i have all the files and they refuse to install.
