scheduled checkdisk freezes at 83%,

I setup a full scan of my hard drive. Upon restart the checkdisk program starts and that is where my problem begins. It checks ok through steps 1,2,3,4 but freezes at 83% on step 5. PC is locked cannot do anything. Power off and on again, checkdisk starts again, try hitting any key to cancel but it does not recognize the keys and starts the scan over again and with same results. How can I cancel the scan and restart my windows os?

 

did you try defrag it, try that if not then register below at the site i will research your issue

 

can't defrag...system freezes in chkdsk screen...have to power off/on to restart. Tried using repair console from xp install disk but c:\windows avail commands does not let me cancel or get to a command line
