Every time I turn on my Toshiba Tecra A2 that runs XP, it goes onto a black screen with cursor flashing. It has the word Password just before the flashing Password word. I cannot remember any password for this. When I try what I think might have been the password, after 3 attempts, the laptop switches off. I try to turn it on with pressing F2, F8, F12 but it goes to the same black screen. I have also tried inserting Microsoft Office , Student and Teacher Edition 2003 into the cd drive, but nothing appears on the screen.
