any one can help me? or I have to reinstall Fedora again because I do not work without SELiinux or system monitor. I do not want to reinstall because I have undated and set up the entire system it's almost 1 GB download I do not want to loose it and do it again because I am using low bandwidth so it's very hard to do.

Maybe the installation got somehow corrupted through the dirty shutdown. Did you already use the disk utility (Application - System Tools) to check the disk for errors?
