|Not too sure what the 'zero key' bit is, but start off by tapping F8 as the system is booting up - this should get you into the screen to choose 'safe mode' etc. Does this work & can you get to your safe mode desktop? If not then the next option is to get hold of a Vista rescue disk, or a full version of Vista - press the 'boot order' key on boot up (I think it's F12 on a Toshiba?), select the CD/DVD drive and boot from this then choose the 'repair my computer' option when prompted. If you cannot even get as far as this then it's almost certainly a hardware problem and if it's a laptop then you may need to take it to your local tech.|
