Your machine is telling you that you have, "2 beeps = Incompatible RAM type installed (for example, EDO)"

Please remove all added memory and give it a try.

Thank you so much this worked for me, after I had placed the original ram in different slots. I'm to scared to put the "added ram" back into the computer.


Gus, if you have more RAM but all the same type and brand, you can put that in and remove the original RAM.
