The Optiplex 745 is only good to 1066MHz FSB, but your new chip, the E6750, runs a 1333MHz FSB. Chances are that the board doesn't recognise the pin configuration on your new CPU..
Basically, you can't use that chip in that computer. A lot of people have used 1333MHz FSB chips on i965 just fine, but that's what you get for buying a Dell
Seriously though, if I were in your situation, I'd sell the E6750 and buy myself an E6700 instead or something similar. Or spend the money down the pub..
