If you are hearing beeps when the computer is turned on, the beeps are a code saying there is a hardware problem that is preventing it from booting. It could be keyboard, mouse, memory etc. Try to find a manual for that machine and look up what that coded sequence of beeps means. It works like two long and 1 short beep might mean memory for example.
