So far all involve registry cleaning. None have been fixed yet so I'm guessing the damage is deep.
When I first loaded Windows 7 Ultimate (32-bit) on my Dell Vostro 1320 notebook, everything was perfectly fine. Lately, the built-in defrag tool won't work because it doesn't show "C" drive (which is my boot drive) in the drive list any more.
As a side note, it might also be part of the same problem, but chkdsk won't run against the C drive either.
Any help is appreciated because I need to get my chkdsk running again as I've got drive errors that need to be fixed.
