I realize that there are some old posts on trying to upgrade this machine. I've done a clean install of Windows 2000 and the video display fills out only about half the screen. I've gone to Drivers.com and the Toshiba tech site and not been able to find anything that looks like a video displaydriver for Windows 2000 on this machine. I know there is one out there, because my nephew was able to find one before, but I no longer have access to it. Thanks for any suggestions.
