Win7 Black Touch Updated 1-15-2012

I hate to be a nuube to this, but.... dealing with an aging machine, I'm applying all the 'speed up Win7' tips, including turning off Aero, themes, all animations, transparency, and using only the Win7 basic (light blue) which isn't very attractive. I'd love to use your Basic Black theme and get the black design, with low cpu load on the graphics card -- that is the idea, right? Anyway: how? Are there detailed instructions? Thanks!
