Wamp vs Skype

If Wamp stops running for no reason — that’s maybe because of Skype. Try turn Skype off or go to Preferences and change listen port to something else (instead of 80).

Another solution would be changing your default localhost port to something else rather than 80 (because 80 is kind of popular and being used by a number of programs). To do this in Apache you need to edit httpd.conf file.

Port conflicts like this may also apply to IIS vs Skype or IIS vs Wamp.
