Help with pc after crash.

[smoky]

I just want to be sure we we understand, You Did ctrl + alt + delete at the very end?
i mean, at this moment : "it stops at the black screen with mouse cursor."

if yes, that's bad ...

the next thing i will suggest, would be to try to repair damaged files with start with a windows CD as i said earlier, but i would have preferred first that we can saved some files as a precaution.
