what did you do last ?
and it WAS NOT installing updates .There have been NONE for a year - fedora 11 is PAST it's "End of Life"
do you have a full back up ?
if so install the current fedora 14
also please describe IN DETAIL what this means
after logging with user name and password it is neither directing me to main screen nor showing any errors
a black screen with NO TEXT ?
or is there the text login?
can you boot into single user mode ?
can you boot using the old install cd in " rescue mode" ?
