A CMS typically consists of the web server, the authoring programs, and the database underneath it all.
To create a simple CMS is like creating a simple jet airplane.
The one method that would be efficient would be to load up the free VMware ESX hypervisor and then download/install a pre-built VMware CMS appliance. There are pre-built appliances for Squiz, Drupal, Joomla, and others. These have the database, CMS, web server, and underlying Linux server all pre-built...just copy, do some minor config, and it's a full CMS.
If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem. Also please exercise your best judgment when posting in the forums--revealing personal information such as your e-mail address, telephone number, and address is not recommended.
