The reason your keyboard don't work can probably be anything from BIOS failure and some hardware failure, to some trouble with your harddisk, or only a broken driver file for the keyboard. But if it's possible and you do not loose to much value on your harddisk, try boot on your Operating system disk, do a full formatting of the harddisk and install your operating system again. If the keyboard do not work then, you may be schould update your BIOS, but that can be impossible if the keyboard do not work. May be you can get a new BIOS-chip and let some one replace it, if it is placed in a socket. If that do not work.....:-(
