You say you're read the tutorial - read it again and see what you find.
To "change the color of the pic", you need to change the red text at the top of the script to the name of another one of the .inc shaders. It's default is "glossy.inc". You could change it to "milk.inc", for example, by replacing "glossy.inc" with "milk.inc".
Read the tutorial again, and go through it step-by-step.
You might want to update your graphics card drivers to the latest version. If your graphics card is simply too old and/or not powerful enough then you might want to turn off some of the settings in the setup menu (e.g. fluid blood and such). If they still don't work, then I don't think there's anything you can do but buy a new graphics card.
Also, your explicit comments are unjustified. Pull yourself together.
