CPU replacement

First no you an't upgrade to an I7. As unreal has already pointed out your computer uses an AMD socket and you can't put an Intel CPU into an AMD socket. As for weather or not you can upgrade at all I would say probably not. The A10 is pretty much the highest-end APU you can get. There really is nothing else to "upgrade" to. I would say your stuck with the A-10 and as unreal said next time look at the specs.
