after looking at a lot of SANDRA's tips they seem to be pretty general, and maybe not for my machine.

I was going to say the same thing.!
Most of the tips offered by the program are pretty lame so I just don't even pay attention to them.
As long as your computer runs fine and just the way you like it, don't customize everything just because ... and trust me, you probably wont get much difference by disabling the wallpaper and all that stuff if you have a fairly decent system (at least 500mhz and up! ).
