I am having Windows XP installed on my system. I am trying to install a new software. But as the setup run the entire operating system freezes a lot during the process. I am unable to find the reason behind it. Upon restart there is a error message on the screen. The message says some Autochk.exe not found - Skipping auto check. I do not really remember that I had installed any software or application which is named as Autochk.exe. How can fix the same.
