My PC ran an update overnite. When I tried to use it the keyboard would not work. I tried to uninstall, reinstall drivers, I bought a usb keyboard. I keep getting the same code 39 error(drivers corrupt or missing. I have a driver cd for the new keyboard but still does not work. I have looked all over the internet and could not find a solution. Many people have had this, but no solutions posted. I do not see any keyboard settings in my bios, only ps2 mouse. Help please...
