I installed new memory but still get 3 beeps
I installed new memory & still get 3 beeps, have tried to reseat a few times, still same result. I did carefully vacuum inside, could I have damaged the logic board? The Mac was previously getting some lines on monitor Occasionally . Logic board was replaced 4 years ago. Thanks
Is dit een goede vraag?

Are you sure you have the correct RAM?

Does an external display show the same lines? If not then the internal display will need to be replaced.

Thanks Dan, yes I have the correct ram. I will try with an external monitor once I get it going.
