Chkdsk Utility

Be patient - I'm new. The last 2 times I have run my CCleaner, it has given me a warning message that one of the temp files is corrupt - it tells me "please run Chkdsk Utility". Where do I find this utility and does anyone know why I am all of a sudden getting "corrupt file" notices?
