Windows CheckDisk (chkdsk /f) Runs After Every Restart

Hi,
I'm running Windows 2008 as my server for an internet cafe. My problem is it runs checkdisk every time the computer restarts. I even allowed it to finish so the check disk won't appear again but it is stubborn and is starting to annoy me.
People would have to wait a few minutes before I can let them use the computer.
What can I do to solve this problem I'm having?
