At the password screen, hit enter 3 times and you should receive a 'halt code' - post back with this code.

Hold down the power button for 10 seconds to shutdown the notebook.

Start the notebook and at the password prompt type in the unlock code 61631226 and then hit enter.

Good to hear.

Regarding the subsequent issue, the first thing I'd suggest is to run a diagnostic on the storage drives as follows.

Shutdown the notebook. 

Tap away at the esc key as you start the notebook to enter the Start-up Menu.  Select the Diagnostic Menu option ( f2 ) and run the tests on the Hard Drive.

Post back with any error codes that may be generated.

If the drive test(s) pass, you could try to reset the notebook to its 'Factory Condition' and then set it up from the beginning – if you don’t have your Recovery Media, the notebook will have shipped with a Recovery Partition which can be accessed at boot - ie shutdown the notebook, then start tapping away at f11 as soon as you power on.

A full guide on this can be found on the following link.
