Might I suggust creating a restore point, incase something goes wrong. Start, then programs, then accessories, systom tools, then system restore. Then create restore point, and name it what you want.
This way you can restore your cpu back to the way it was, if something bad happens after the download. Whether you download it or not, is up to you.(Make sure your at a credible site. If your downloading directly from the gmax homepage(discreet?) then it should be okay, if not, it's up to you.)
A book? I hate book. Book is stupid.
