Hope this help.

The Toshiba Qosmio G25-AV513 supports a maximum of 2 GB of RAM, not 4.

This won't be good news, but looks like the best answer. I located this solution on Toshiba support forum.

You could try the solutions provided in this article or you might have to contact Toshiba Tech Support. Have a nice day.

Try booting up in safe mode (tap F5 as the computer starts up until you get the black screen with white text and select Safe Mode).

Log in as Administrator. With any luck you will have no password for the Administrator account.

Go to Start->Run
type CMD and hit enter

You'll be at a command prompt. Substituting your user name for <username> and a new password for <password> type in

net user <username> <password>

Now your password has been changed. Reboot into Windows and log in.

there should be a jumper on the motherboard . If not disconnect the motherboard battery , the small disc , this will clear the bios so only do this if you can't find the jumper.
