SFC/Scannow will not open

Where/how are you trying to run it?

Open a Elevated Command Prompt and try running it there?
Do you get any error messages?

Go to Windows start and in the search type cmd
You will see cmd.exe appear up top, right click on cmd.exe and left click "run as administrator"
In the window that opens type sfc /scannow then enter.
Note that there is a space between c /.

Did your cmd window open ?
Please fill in your specifications so people can help you better.

Thanks

I think when you entered sfc/scannow, that brought sfc.exe up to the top. When you run that as Administrator, no parameter gets passed so all you are running is sfc, so the window opens and closes quickly.
