Then, power the machine up so, that, it can start the unpacking of the pre-installed compressed files of your new Windows Operating System.

Windows 7 I presume.

The windows setup has to install the generic driver to use your monitor right away. If monitor not responding, it is not fully compatible with Win. 7.

I have this problem with my 22" widescreen monitor since Spring of 2009. Now, put away for use with the older, single core machine that, has the Win. Vista SP2 on it.

What says 'Works with Vista' or 'Compatible with Vista' does not mean it will be fully or even, partially compatible with the Win. 7 version.
