Settle down and be more specific, man.
How many beeps (I figure that's what you said by "pulsating"), (short, long) and wich motherboard do you have.

open the case up and pull out the ram sticks. blow some air in the slots you pulled the ram out of and put the ram back in and make sure they are firmly clicked down on both sides. turn it back on and see if it works.
