Hi guys, My mac stopped working, and when i performed the apple hardware test it said that i had an issue with the heat sensor of the HD, so i replaced it with a new one… Now, when i try to start, the symbol of the bin with a “?” in it pops up. Thats normal, since i don’t have the system installed on that new HD.. but when i try to start with the Instalation DVD, the mac starts to BEEP… In the internet, some people said it could be a problem with bad RAM, but i’m curious by why this happens only when i try to run from the DVD.. Can anyone help me?
The three Beeps indicate a RAM issue. First try reseating the RAM. That failing, insert just one stick at a time to test both the RAM and the RAM slots. Either can fail. You may also have hard drive temperature sensor errors when changing drives on this model. Again did you change brands? OWC makes an in-line sensor that solves the run away fan issue (if you have it).
