I bought a used Toshiba Satellite c655-s5060 yesterday. Brought it home and realized that it had some type of virus (random audio started playing and it would prevent updates and most recovery methods). I attempted to factory restore it and part way through the recovery process I received an error message saying that I needed to shut the computer down. When I started it back up it only loads the title page and then goes to a black screen with a cursor on the upper left hand corner. It will not go back into the recovery page (holding 0). Please help!
