I recently installed SP2 on my Dell 4400. It was purely accidental. I didn't think about the problem, and just got the recommended updates. Oops. Well, now all I get is a black screen after the initial flashscreen. Try repairing or reinstalling from CD? Sure, but I can't. It checks my hardware config, then just... keeps checking, or at least claiming it is. My PC sits absolutley quit, processing nothing, yet my monitor displays that it's checking still. It's really starting to get me angry, so any help would be more than welcomed. Thank you.
