Can't change resolution in Win8.1

Did you install Apple's Boot Camp support software after installing Windows?

I've installed Windows 8.1 onto my brand-new Mac mini, and I cannot change the resolution without it going into "snow mode".

Why do you want to change the resolution? If it is for vision problems, it's better to change the screen DPI that windows uses. It's under "Make text and other items larger or smaller" in the screen resolution settings.

I'm also having problems with the internal speakers. System Sounds are coming through, but Chrome isn't.

You probably went into the mixer, and set the volume for applications really low. Press the speaker icon and hit the link 'Mixer' at the bottom. Side them all the way up, then adjust how you want them.

Over the years I have learned apple makes poor Windows software , The bootcamp drivers do not work good and I really recommend you try installing Windows in virtualbox it is free . You could also try installing in Vmware Fusion or Parallels but you will have to pay for those two programs . I thought Vmware made a free program called Vmware Player but that is only for Windows and Linux .
