Have you upgraded the IOS lately?  Some times this happens, because you have loaded the wrong IOS on the device or the image was corrupted during download.

If this is not the case, then you can boot the router to Rommon and try to add the boot variable for your IOS and boot it.  If not, then you may have to download a new IOS and use Xmodem to loaded.
