When i try to input my password, i try to type the letter 'n' and for some reason my macbook pro chimes. I have no idea how to remedy this problem. Any advice would be greatly appreciated. Thanks in advance.

Its a mid 2009 macbook pro, i don't really know the system details. I have no idea how to change the password. And now when i start up im getting a picture of the macintosh hd with an arrow pointing at it

This is the Boot Selector or Selection Manager and shows all bootable devices currently connected to your Mac.

Choose the one with the name of the HDD where Mac OS X resides and press ENTER (in the above image it's the HDD named Macintosh HD, the name all Macs' HDDs have upon delivery).
