Sorry...but probably not as I had to have a buddy help me with the same thing on my laptop.lol.

What I was suggesting was to just get a long phone cord and run it directly from the plug under the service cover of the telephone box outside(there should be a short tail in there you can unplug giving you a jack to plug into)...directly into the back of your computer just to check the phone line connection.
If this fixes it...then you know where the problem lies...if not...then you've ruled out the phone line issue.

I'm sure someone here can walk you thru your startup issues.I've got just enough knowledge to make me dangerous...but not enough to be helpful to you in this situation.Sorry.Good luck. ;)
