What is the cause of my tremendous amount of FEC and CRC errors?

(I apologize for not knowing all the correct jargon.)


I am very perplexed and frustrated. For over 6 weeks I have been having intermittent disconnections from the internet which prompted my calling my DSL provider (the phone company). They have come to my home several times. They've changed several wirings, switched out the modem, checked the phone lines, monitored my PC for errors, etc. During one of their visits, they showed me a way on my computer to see the errors I was getting. After their "extensive" work, they finally told me yesterday that the problem was with my computer. Their first suggestion was to upgrade to Windows 10 and then get a new network card. But then, they said it could be a virus.


I get tons of FEC and CRC errors almost daily. They can appear at any time; there seems to be no real pattern. I can be e-mailing, working, playing a game, or nothing at all. To give you an example, in the past 24 hours, I have had 5,205,160 FEC errors and 1,063,952 CRC errors. They continue to flood in as I am writing this. In one 15 period today, I had 396,474 CRC errors alone.


Another weird thing is that my modem's lights (e.g., Internet and DSL) are often lit even when I have no internet connection.

I am using Windows 7, Intel core processor, I7-4770K CPU @ 3.50 GHz, 64-bit operating system and 8 GB of RAM.

Is there anyone that can PLEASE tell me how to resolve this problem? The phone company has given up and told me that I will have to pay for any more of their visits regarding this issue.
