Impossible.
You are running an all in one pc? It's got probably a second generation Intel cpu.... And the 6600k/7400 is not compatible. This whole PC is not upgradeable, you can put done more Ram and cpu of its generation. But either, your options are limited because this is built like a laptop. It would be better to try and get a budget tower build, which would benefit you alot since this AIO is so old
