That seems like a hardware issue based on the computer's specs. Try the ones that don't work in the slots that already work or the opposite to see if the result changes. I suspect you will find out that either the sticks or the slots are bad, or that they are not properly inserted. – Julie Pelletier – 2016-07-08T19:31:11.693
