When I turned on my laptop this morning the screen said "scanning and REPAIRING drive (C:) 0% COMPLETE" what is this and what caused it? I have had a problem for the past month or 2 where I have heard something rattling around inside my fan and I am unsure if this has caused the c drive to be messed up.       

I'm scared that whatever this is MIGHT delete some of my files or something

Any ideas on why this showed up? And what is this drive for will it affect any of my files? Etc.

Please help asap

2) Right-click on a command prompt icon and open as administrator. In the command prompt window type: chkdsk /r  (then press ENTER). You'll be told the disk is in use and asked if you want to run checkdisk on the next boot. Say yes, EXIT the command prompt window, and reboot.
