|I am guessing the computer is not the one listed in your specs....the Toshiba|
knowing the brand can help with getting the right key to get into the bios.
Was this a factory cd? and when you re installed did you boot off the cd or try to install when windows was running.
When it stopped did you get an option to press f1 to continue?
Also...the inevitable question......why were you re installing....virus....corrupt OS
or other reason.
