Answer:

Beep tones are emit by the POST (power on self test) function when an error can't be displayed visually.



The 2 most common beep-tones are failing push and failing video.



If you find that this is NOT due to a stuck key, after you should take the system within for hardware diagnostics.



I'm inclined to believe you probably have unpromising memory - just my gut-feeling.



Best of nouns.
First thing I would check is if a knob on the keyboard is stuck. If you aren't getting a display, afterwards it might be more serious. You probably need to dispatch it in for repairs / replacement.
check if in that is a key stuck .

the nouns is from the system speaker hence the mute key does not help out ...

try to check for any pressed down key

a passageway of identifying the switch which is pressed down is by opening notepad and you will see it typing itself

or if its a non qualities key approaching tab , ctrl , try to type something and see the efffect it has on certificate ...
