How would I wipe a computer without an administrators password?

Well long story short we got a computer from a business which closed.

Now we can't do anything with it due to no administrators password in which to login and allow access to everything.

The internet does not even work its so tight on security ( medical pharmacies old computer ).

Now I just want to know if there is any way to hack into the admins account ( do not know the login or pass) or is there a way to just wipe the whole computer and start out fresh.

We have tried to put in the OS cd and it won't even let us go from there its so secure.

Then it will boot from the CD and you can install your operating system.
