POST (Power On Self Test) is what you are hearing. A hardware part is not initializing or registering properly.
Commonly, beeps are heard singly, or in twos, or threes, or fours, or fives, or any variation of the preceding. So, it is possible to hear a one, pause, followed by a four. If this is the only error, it will repeat if the system fails to boot into the operating system.
Never heard of 40-50 beeps in a row.
Every computer system actually has two operating systems on it: BIOS, and the actual operating system you interact and work with.

Depending on what error code is presented, you will have some options.
If under warranty, back up all important files before sending it in, and have the repairs done there.
