If you computer was crush, if this is the scenario: you can't boot up your computer or you can access to your operating system , you can still access through your files if you did not format your drive. The question next will be how?... you can remove your hard drive and you can connect is as slave using other desktop or computers... i know you cant do it yourself... it need someone who can understand the procedure... better look for someone who are able to do the procedure... now you worries regarding your ID and password has a solution. Next problem is finding the technician who will do it for you personally.
