Bad image error message

[Marzmlol]

Hi, recently my computer has been receiving the bad image error messages. Whenever my computer starts up these messages pop up. I can't open any programs either. (games, itunes, skype, firefox/IE,etc) Whenever I try to open them up I get the bad image error with the C:/windows/system32/winnsi.dll is not designed to run on windows or it contains an error.

I am running on Windows Vista.
Help please!
