Why does my computer make beep noises?

I'm experiencing a beeping noise coming from my computer. If I put in a headset it will stop, but if I tap my headset it will make the beep noise. Same as for the laptop, if it does stop (rare) I give it a little tap to the right of the touch pad it will beep again. I don't know if this is because the microphone is catching the noise or if its an internal hardware problem. Here are my laptop specifications:

Are you sure you don't have a button stuck?

Maybe this could be help you (?) : http://www.pcmag.com/...beep-codes

Cat. That s all

It sounds like a stuck key on the keyboard. If it boots up normally except for the beep, a key may be stuck on the keyboard. If so, try looking at the control panel and it might identify the faulty key. A good visual inspection with the unit off could give you an idea of which one. Press each key, even the function keys and numeric cluster, see if they feel okay or don't seem to have the same ACTION as the rest. Maybe one is stuck down or feels funny. The space bar is the most common culprit.
