Please don't type in all caps, and please use proper punctuation and sentence structure... otherwise it's very difficult to try and discern what you're trying to say.
Insert your Mac OS X Install/Restore CD/DVD, then reboot your computer and immediately hold down the 'c' key and keep it held down until the computer boots from the CD/DVD. Then, follow the simple on-screen instructions and prompts to reinstall your system.
