You might start by looking in the error log. On Slackware, it's located in /var/log/apache. I don't know anything about fasf, never even heard of it (for that matter, I don't know where fasdf is, either). Anyway, that might give you (and us) a clue as to what's wrong.
How did you install apache, from source? Did part of the install include editing the httpd.conf file? Give us a little more info.
