I allowed an update to Messenger yesterday and it started having problems. It
would connect then fail and close. I decided to roll back to the last system
restore point. When the machine came back up, it came up to a black screen
with the mouse cursor visible and the Vista build information in the bottom
right of the screen but no key combination will work. If I leave it on long
enough, the screen saver will even come on.

I have to do a full power-down to turn off the machine, which is a Dell
Latitude D820.

I have tried booting in all 3 different safe modes and they all come up to
the screen with "Safe Mode" in the corners and the Build information at the
top. The only thing I can do at this point in the boot is move the mouse
cursor around or power off.

I then tried booting from my disk and using the repair functions. the boot
repair reports that there is not a problem, the memory test is fine. if I
select the system restore it shows all my restore points and lets me do a
restore. I've tried virtually all of them with the same results.... after
quite some time of restoring I get the "finished" message then an error
saying the restore failed because it couldn't access a file.

I am totally stumped on what to do next, and would greatly appreciate any
help anyone can give.
