Tell what you do (while trying to backup and the exact error message. However, this might be a sign of a failing hard disk. Then you might be too late with the backup.
Please also tell your OS.
I went away for the weekend and came back to discover that my laptop no longer will start up properly. For one it takes ages to even load xp and then often takes hours loading up everything else. I got a message saying HD failure is emminent and that i should back up files. However when i finally get into windows and try to back up the files it says there was an error and it was cancelled. So i'm deathly afraid of losing everything on my computer, anyone know how i can somehow back everything up? and also can anyone tell me what could have happened over a weekend to cause my computer to go to hell and back? it was running perfectly before i left and i got back and now it's crawling. Thank you help!
