first of all, you should be aware your computer needs to be on all the time. As soon as you shut down your computer, your site goes down.

That said here's how to do it:
1) First check with your ISP if you have a fixed IP address, a dynamic IP wont work. After that check with your ISP if they allow hosting sites. Some dont.

2) Download any web server like the Apache server, if you are on Ubuntu, here's a simple tutorial to do it

3) After installing copy all your files in the www folder or htdocs whichever is there.

4) Put it online, on linux it will already be...

5) Point your domain name to your fixed IP address and redirect ports if necessary.

6) It should work. Just recommend you to take some book or professional tutorial before doing that on a production site. If you are just trying, experiment with it.

Just one advice, take a hosting, its better because the servers are handled by professional companies and have almost 100% uptime guarantee. Also in the long term they will be cheaper because you will incur high electricity and internet costs in your home hosting.

Hope that helped you.
