You can buy another set of recovery disks from Toshiba

Open CPU Cabinet's case and look for button cell of coin size on the main motherboard(circuit board) and push the pin with holding the button cell, the cell will come out. This will power off the BIOS memory and the BIOS will reset.

After you logon, you can remove the account password in Control Panel.
If you forgot Windows logon passowrd, you can create a Windows password reset disk to reset your lost or forgotten Windows password, i have created one with the tool Windows Password Breaker and reset my administrator password successfully.

Yes.

Press F2 or Esc key on startup to enter BIOS settings.

You can find the option for factory reset.

Toshiba Factory Reset
a couple of ways to do that 1) if you have the recovery CDs supplied with the PC - then you can use these - put the CD into the drive and when it boots follow the instructions 2) If you have a recovery partition on the laptop - have a read here to see if you have one http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/outFrm.jsp?ofId=AskIris&searchString=recovery+to+factory 3) This link shows you how to use the partition http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/bulletinDetail.jsp?soid=2291088&pf=true basically as the PC boots TAP F8 key - from the menu that appears choose "repair your computer"
If that option is NOT available then you will need to Order CDs from Toshiba - http://laptopforums.toshiba.com/t5/System-Recovery-and-Recovery/Recovery-media/m-p/9148#U9148

Are you able to get in in Safe mode (F8 on boot) , maybe try Administrator with no password. Then you could reset your admin password.

What operating system are you using (ie Windows 2000)

Try re-installing the Video Drivers Available Here

You will need to either:

Contact Toshiba to supply a restore disc.

or

Borrow an operating system disc from someone you may know and use the Windows COA that matches yours (eg. Vista Home Basic) to reinstall Windows.
