I have used dial up internet satisfactorily for 2 years and suddenly it doesn't work. I receive a "modem not found or busy" error. I have checked all the cables and looked at the modem set up. Phone & Modem Options lists the modem CNXTV9xPCI and "Not present", Device Manager doesn't list any modem, and System Information shows all the modem info.
The only peculiar thing was that my phone code had changed; this I put right but it hasn't made any difference. I am the only one who has access to the PC.
An expert has told me that modems can't go wrong and as there is no problem with ISP the problem must lie with the software and I will have to pay for fixing it....Unless some kind person can help?

"An expert has told me that modems can't go wrong ..."

You need to find another "expert."

I don't claim to be an expert, but I consider the dial-up modem to be perhaps the part of a desktop or laptop computer most prone to being fried by a small electrical surge (over the phone line). If you have a physically removable modem you could remove and then reinstall it to see if that makes any difference.

I can't guarantee that your modem is fried and that there is no software problem, but that is my suspicion.

I agree with TerryNet. Modems can be a real pain. Heat, lightning, and static can cause the smaller chips on modems to give up the ghost. Sometimes everything will look fine, drivers will load but nothing works. You might pull it out (assuming it's an internal) and take a close look at it for popped chips or heat damage.
