that's technical mumbo jumbo that means they don't have a clue what's wrong wiith it but we'll be see you back again shortly fourisis. if you post all that you can of your computer specs, including software, chances are you'll get a lot more help here than their nonsensical diagnoses.
edit: just read this again where cox said the problem was on their end. if something on *their end* harmed your computer then write them and demand restitution. if you've just been without service most *reputable* ISP's will deduct your bill prorated by the number of days out of service. they will not do this automatically. you have to ask to have them do it.
