Old MacBook Pro - randomly starts beeping for a long time and then crashes

I keep my MacBook on most of the time and randomly (sometimes days apart) it starts to beep continuously and then crashes. If I catch the beeping and force quit (the screen has usually gone black and won't let me shut down), I can then start it back up and the beeping usually doesn't start right back up.
