My macbook beeps three times on startup (but then doesn't start up). I heard that a hair dryer works if pointed at the Ram slots. Where are the Ram slots on my macbook?

3-Beeps is RAM/. I would not use the Hairdryer. How old is the Macbook? It's a Macbook and not a Macbook Pro right?

Open the back, remove the battery, remove the shield, pull the ram module tabs upward and remove the modules. Replace the tabs and re-seat the modules, replace the shield. Replace the battery, close the machine and try booting again. If you get the 3 beeps once more, replace both modules with new ones.
