is my non-compete enforceable

Hello,
my company was recently acquired, and I was asked to again sign my non-compete, as the original was supposedly lost. The non-compete carries over to the new company. The specifics of the non-compete state "While employee by company and for (12) months after Employee's employment terminates (the "Non-Competition Period"), Employee shall not, directly or indirectly, whether as owner, partner, investor, consultant, agent, employee, co-venturer or otherwise, compete with Company or any of its affiliates within a 50 mile radius of any PSG office or undertake any planning for any business competitive with Copany or any of its affiliates". The company in question is a consulting firm that provides consulting services for the installation, configuring, training, etc, on all Microsoft products. Since my residence is within a 50 mile radius of the nearest company office, I affectively cannot even work out of my own home in the same field (time for a career change?). Therefore, I most likely will not even be able to provide for my family for a period of 1 year after resigning from this company. In my opinion this is too broad and unenforceable. I would greatly appreciate consulting with an attorney about the validity of this document.
