If you still wan tto install the better drivers, go to the original downloaded file - it is an extractor. For easiness extract to your desktop. As well as loads of icons you will get a proper executable file that will install the drivers, follow the on-screen instructions and you will be fine. However, you then need to activate those drivers instead of the current default onesin use at the moment. If you do not get any instructions on how to do this, say so, and i will help.
