I just reinstalled on an Asus P5Q SE PLUS. Everything was fine until I accidentally checked the optional update for the lan driver. I already knew to avoid it because of past experiences... this updated driver nukes the lan. It just won't connect to anything. Installing the driver from the asus site doesn't help, and just uninstalling the driver and letting windows reinstall doesn't help because it just reinstalls the new driver... and of course there's no option to uninstall the update started it all. I'm guessing it overwrites the files for the old built in driver. The only fix I have yet to find is to reinstall your entire OS and never update that driver. If anyone has any better suggestions I'm open to it. I've run into this type of issue a number of times now. Nobody at MS is testing these damn optional updates in the field, and or they're entirely ignoring feedback. To this day the optional driver for my monitor causes horrible dithering in the built in picture viewer. It's this kind of half-assed crap companies making large sums of money do all the time that make me feel like starting some sort of action group, like consumers against incompetent monopolistic companies, or NAMBLA.
