OS is Vista Home Premium on a Lenovo 3000 N100 laptop. Cannot run chkdsk as an Administrator. Tried running chkdsk /f. Computer boots up normally without running chkdsk. I even tried running in Safe Mode. No luck. I ran CHKNTFS /c C: and after running it stated "Windows Resource Protection found corrupt files but was unable to fix some of them."

Any suggestions would be appreciated.
