    can you give us more info? like what beep sounds are they and if in any combinations? (long, short, continuous etc)
    steps you've done in troubleshooting?
    read this guide:

    right now what you've said is a bit ambiguous..

    maybe your buttons (for turning off, on, restart) are wrongly wired

    Beep codes always mean something, but differ from computer to computer. You can usually, but not always, find a list of the beep codes on the computer manufacturer web support site. Try, also, a Google search for "<brand & model> beep codes"
    Usually the beep code is signaling a bad memory module, failed video graphics, failed CPU fan, failed hard drive, or other such critical component. The beep code is to alert you that the error is basic and you will not see useful details on the screen.
    Try to boot up with the case cover off so you can see if the cpu fan is turning, or if the power supply fan is turning.
    If you have a floppy drive, you might want to find a floppy boot disc such as Windows 98, then disconnect everything but power supply, cpu, one memory module, and video graphics connection. Then boot to the floppy. If the same error occurs, you know it is a fundamental error. Then trade memory modules, and try again.
    This exercise will help you narrow down the problem... by adding components until it fails once more.

    Still, it is not "fine" now as something has gone bad. The beep codes help tell you what that problem is.

    Also, what is your system? What are the specs?... Like make, model, operating system? Count the beeps. 1, 2, 3, 4... Long like Beeeeeep or short like beep
