Does it give you any error messages at this point?
You might see running a sfc /scannow command can find and fix any system files that may be causing CHKDSK to not finish running. Afterwards, see if it can finish. If not, then you may need to do a System Restore using a restore point dated to when you knew it worked (if known and available).
Thanks Shawn, no error messages, it just stops and will sit there forever if I let it. It has never worked and this is a brand new computer with not much on it other than what came pre-installed. I will try your other suggestion. Chuck
