Virus and inability to log onto internet

[lilbake]

If I have a virus is it possible this is why I am not able to log onto the internet. :-?  I had two motherboards replaced and then I couldn't log onto internet.  I then was told that I have a virus.  I could log in before the motherboards were replaced.  I'm not sure if replacing the motherboard can bring in a virus. :-/  When I tried my dial-up connection it said there was no dial tone.  I went through my provider and there was no problem on their end--all my other computers are able to log in on the same phone line but my laptop isn't able.

Check that the phone line is plugged into the right modem socket.

Replacing the motherboard and not reinstalling Windows can cause a lot of problems as well. Is that what you did?
