Hello, I have an HP AIO computer. I brought it to a store and they told me it was the CPU or Mobo. (They didn't look inside). I am wondering if I can test if the CPU socket is getting power or works to possibly get a new processor. It's an HP envy 20 D030 (With some changes. I upgraded one of the ram sticks and now have I7 3770). I have tried new ram and no longer have the old CPU.
