I dont know what it is but when i open up my computer it comes up and it says that its not working? so i really dont know what to do.
ATI Catalyst Control Centre is a control program for ATI graphics cards. If you have an ATI graphics card, go to the ATI website and download and reinstall the program.
Catalyst is what ATI calls the drivers for their video cards or video devices built into mainboards. Download the newest video driver for your video card from ATI or from your computer manufacturer's site if the video device came with the computer. Install that, and you should be all set. You may want to check your add and remove programs and remove any of the old, malfunctioning ATI or Catalyst drivers before attempting to install the new one. Good luck!
