Hi gabi014,
What make and model motherboard do you have? Does the beeps follow a certain pattern?
Have a look at the manual (physical / find it online) to see what the beeps refers to.
It's most likely going to be your RAM Module/s that's damaged, or the RAM connector on the motherboard itself, but a make and model as well as beep pattern would easily help us identify the problem.
Help this helps,
Fred
