Help with URL on website

for example I install a forum on my website as /boards
when i type http://rconarts.com/board/
it says file not found or it just displays my index.php in the root(public_html/).
Yes i have an index.php in /boards but it shows the one in the root(public_html/).
but if i manually type http://rconarts.com/board/index.php it works.
I removed the boards so dont try going to it now, but i still have the problem.

Answer #1
Are you sure the forum was properly installed?
Answer #2
Yes, this happens with any index.php though.
Answer #3
Is the website hosted on a server of your own (and if so, what HTTP server are you using) or do you have bought a hosting package?
