Try launching the IIS snap in from the run prompt, Start > Run or Windows key + r, by typing "inetmgr". It it dosen't load its probably just rubbish, then try this.
At the run prompt type "services.msc" then press run. This will open the service snap in. Look for a service called World Wide Web... and see if its running. If so set it to manual in its properties and make sure that it is stopped. The next step is to check to see if there is an Apache service registered on the system. If so try to start that and see if it will load.
What we are trying to do here is to verify that IIS is either not installed or if it is that it is not running at the same time we try to start Apache. They both will try and use port 80 and will block the other if it is already started.
