Hi weewards,
I saw your post and I will be happy to help. I am going to need some additional information to help you because if install the wrong driver that could only make things worse. Are you using the same product as the original poster the Envy m6-1232sa or a different model? If you are using a different model can I get your product number.
Find your product number on a notebook:

What I will need is the hardware id like others have posted earlier in the thread. The link below will show you how to find them.
