Very very few PCs just work after installing Windows (any version.) After the OS we have to finish the install with drivers in a specific order as well as some machines require "helper apps" to enable WiFi, sound and more.
No one can answer what your PC needs. But its maker should.
As far as I can tell, everything with my partitioned 8.1 is fine....when I realized tha I have no sound. I think, booting up or in shutdown should produce some kind of Chime/sound. I have none and the little bit of checking aroun seems like the sound settings are on...Then I did a Yahoo and YouTube video and no sound. Need help!
I found the "Microsoft Community Participation Center" and sent them a note. 24 hours later I have 8 views and no replies......I guess it can take awhile?
