Any clues in the \xampp\apache\logs\error.log or access.log files at about the date and time you last tried to access Apache?
Make sure you gave no-ip your correct IP address:
Click on
Start>Run...Type
cmd.exeThen type
ipconfigThis should provide the correct IP for your system.
BTW, did you fix your BSoD issue in your previous topic and if so why not post a reply that your issue is solved and how it was solved so others reading your topic can see that it was solved?
