every time i do something on my computer it goes different..

You don't give us much information!
What part of the screen or window changes color?
What are you doing to reset it?
What Video Card (or chip set) do you use?
Belarc Advisor (free from www.belarc.com) will tell you this if you don't know.

Most likely you are losing your video card or you don't have the correct drivers.
