Hello, welcome to Bleeping Computer!
Besides the guides/tutorials, there's useful information, including "getting started" stuff in the New User Orientation
forum, and in the "sticky" topics at the top of forums.
If you don't meet with success sorting it out for yourself, don't hesitate to post a request for assistance in an appropriate forum. e.g if "cut" means a power outage, and you suspect the hard drive has been damaged or corrupted, choose Internal Hardware.
