I have a Toshiba laptop computer. It has been working okay but now a message came up saying \" an internal stack overflow has caused this session to be halted. Change the stack setting in your config.sys file, and then try again.\" The problem is nothing happens when I hit control, alt, delete or turn the computer off and try booting up with the boot disk, or try anything else the computer remains stalled. When I restart the computer the same message comes up and just stays there. Any help would be appreciated. I can\'t change any settings because the computer remains stalled.
