Post back if your still having issues.
Chkdsk runs when I start my computer. It completes 3 of 3 stages. Apparently it finds nothing wrong but then it just stops. It won't reboot the computer and I can't get out of it unless I shut off the computer but when I start it again it runs the chkdsk again with the same results.
How do I stop this?
