I am having exactly the same problem within one day with two different Win7 64 Dell Inspirons in two different buildings - both less than 6 months old. Booted up, got "Starting Windows" screen, screen goes black, mouse cursor is there and moves, but nothing works. Will not boot in safe mode. Windows repair says that it can't find anything wrong. Got one brief flash message that there was something possibly wrong with a plug and play device driver, but could never duplicate it to see it long enough to read it all. Dell and Windows System diagnostics all passed. Virus scans were clean. I was able to fix one using an old system restore point (from a month ago).
The other is a mystery. I only get 3 restore points and none work. Makes no sense, as this is the slightly older of the two computers. I had a huge list of restore points on the other. System restore was not switched off (by me).
Went on with Linux and pulled off the files I need (Fedora 11 Live will mount a Dell/Windows drive - no permission issues). I have some software, though, that I can't really replace.
Was this a bad update......mmmmmmmm.......or is there something else out there. Looking for some direction to avoid the reload and to prevent in the future.
