Have you applied the Micrsoft fix awhile back, when the Blaster worm came loose? If you haven't applied those patches, you are vulnerable, and might be infected with the worm virus. I know for sure that when you get infected with the worm virus, your computer will disconnect itself from the internet.

If you did applied the patches, I think it might be something with the OS. I usually do a clean installation to remove previous OS drivers and problems.
