Clearing Port 80

[Gafaddict]

I recently removed Apache (along with PHP and MySQL -- only extensions to it I had) from my system (Windows XP Home Edition, SP2) as it had simply stopped working and nothing I attempted could get it to work again. I tried to install an older version of it, 1.3, but whenever I try to do so it tells me that a service is still using Port 80. Whenever I try to access localhost, localhost:80, 127.0.0.1, or anything of the like, I simply get a blank page rather than a "address cannot be resolved" error or something similar.

I looked at my services list in Computer Management and it didn't seem to be there... so is there any way to remove this ghost Apache service from my computer?

I tried your suggestion, but none of the returned services were running on Port 80.
