hi

hi everyone. I keep running across a problem that's happened to me before and left me to no other choice buyt to reinstall red hat. for some reason, I had to restart my box, and a couple changes were made, but it booted in fine. I had it console login and well, everything worked just fine. but then I rebooted again,and it asked me for a file system integrity check, then took me to "localhost login"
after that, when I go to type my username, it shows nothing. it's like, it seems to not show anything the keyboard is typing, the numlock buttons come on and off fine, but for some reason, it's just not responding hwen I try to type in my username to log in. any help?
