Scan disk message appearing during start up

[logearav]

Dear members,
Everytime i start the system i get the following message " One of your disks needs to be checked for consistency . To skip disk checking press any key within 10 seconds" I wish that my disk needs to be checked so i didnt press any key but automatically after the specified seconds, the message says check disk cancelled. I performed check disk for c: from command prompt but the problem persists. I don't know what to do. Could some one help?

When all else fails, reinstall windows.
