Toshiba laptop password

Hello,
when he opened it it was in two pieces. He was able to attached the screen back on but it doesn't stay. The operating system is Windows 7 ultimate. He asked me if i could get past the password. Password prevents me from going to the Settings to change anything. I can't install XP becasue a blue screen pops up saying to run ckdsk etc., but I can't. I have tried some password recovery but they just let you see the user accounts and the they want you to buy. they don't let on in the beginning til you wasted time and discs downloading and then get a window sayin to buy the full deal. I'm extrememly frustrated because I have really put a lot of energy into this and I can't get access. I think the previous owner forgot his password, broke it in anger and tossed it. Some of the recovery program had a drop list and I was able to see what was on C drive. There were only a couple pictures and music. What can i do? I do not have a Windows 7, only XP. Any suggestions? I tried boot it HDD, USB< CD/DVD and sometimes I get close and then it will take me to a place where I need the password....
