A couple of possibilities-
The laptop will beep if a key on the keyboard has become sticky- try bloing out kryboard with a compressed aierosl (about a fuver to but)
Otherwise the ram might need re=seating- the onl;y way to check that is to romove and replace the ram sticks- these are under a cover on the underside of the laptop- I suggest that you wear a pear of surgicalgloves when handling them to avoid static electricity from your body (those who do this all the time usually wear an antistatic wrist band )
