I was given a used computer. A bell rings often and I don't know why or how to stop it. Help please?

Question

I can't figure out what is making it. I know how sounds come and go as you get an email, someone signs into IM or something like that but I can't figure this one out.

Answer 1

I can't figure it out. Can you give more details like how it sounds? Is it beeps as soon as the computer boots up? May be a sound of low battery power?
