System restore file folder empty

Hello,
I attempted to do a system restore today. I opened the control panel and clicked on "Select another backup to restore files from" and could see a list of about 5 different times my computer saved itself. I selected the one I wanted and hit 'next'. Then a window appeared that said there were corrupt files in the OS (C:) drive and asked if I wanted to preform a disk check. I said yes, and restarted my computer. An hour later, I attempted to restore my computer again and all of the backup files are missing. Did they get deleted in the disk check? Is there any way to recover them? Thank you.
